STD02N and STD02P
Description
The STD02N and STD02P are enhanced Darlington transistors
with built-in drivers and temperature compensation diode.
Manufactured using the unique Sanken thin-wafer production
technology, these devices achieve higher power levels through
decreased thermal resistance, and can withstand higher voltages
than similar devices on the market.
The temperature compensation diode is integrated on the same
chip as the power transistors. By this design, the STD02N and
STD02P eliminate delays that would otherwise be induced
between thermal sensing at the heat source, and the operation of
the compensation circuitry. Thus, these transistors are ideal for
applications where enhanced thermal stability is required.
This device is provided in a 5-pin TO-3P plastic package with
pin 4 removed. Contact Allegro® for application support and
additional information on device performance.
Applications include:
▪ General amplifier applications
▪ Professional audio amplifiers
▪ Car audio amplifiers
Features and Benefits
▪ Built-in temperature compensation diodes
▪ High power (130 W) handling in a small package
(TO-3P), for minimized heat sink requirements
▪ Built-in drivers and temperature compensation diodes,
reducing external component count and simplifying
circuit design
▪ NPN and PNP versions
▪ Emitter terminals placed symmetrically, pin 5 on NPN
and pin 1 on PNP models, allowing adjacent placement on
PCB to minimize trace length and output skew when used
in pairs
▪ Approved by major manufacturers

WARNING — These devices are designed to be operated at lethal voltages and energy levels. Circuit designs
that embody these components must conform with applicable safety requirements. Pre cau tions must be
taken to prevent accidental contact with power-line potentials. Do not connect ground ed test equipment.
The use of an isolation transformer is recommended during circuit development and breadboarding.
Because reliability can be affected adversely by improper storage environments and handling methods, please
observe the following cautions.
Cautions for Storage
• Ensure that storage conditions comply with the standard temperature (5°C to 35°C) and the standard relative
humidity (around 40 to 75%); avoid storage locations that experience extreme changes in temperature or
humidity.
• Avoid locations where dust or harmful gases are present and avoid direct sunlight.
• Reinspect for rust in leads and solderability of products that have been stored for a long time.
Cautions for Testing and Handling
When tests are carried out during inspection testing and other standard test periods, protect the products from
power surges from the testing device, shorts between adjacent products, and shorts to the heatsink.
Remarks About Using Silicone Grease with a Heatsink
• When silicone grease is used in mounting this product on a heatsink, it shall be applied evenly and thinly. If more
silicone grease than required is applied, it may produce stress.
• Volatile-type silicone greases may produce cracks after long periods of time, resulting in reduced heat radiation
effect. Silicone grease with low consistency (hard grease) may cause cracks in the mold resin when screwing the
product to a heatsink.
• Our recommended silicone greases for heat radiation purposes, which will not cause any adverse effect on the
product life, are indicated below:
Type Suppliers
G746 Shin-Etsu Chemical Co., Ltd.
YG6260 Toshiba Silicone Co., Ltd.
SC102 Dow Corning Toray Silicone Co., Ltd.
Heatsink Mounting Method
• Torque When Tightening Mounting Screws. Thermal resistance increases when tightening torque is low, and radiation
effects are decreased. When the torque is too high, the screw can strip, the heatsink can be deformed, and distortion
can arise in the product frame. To avoid these problems, observe the recommended tightening torques for this product
package type, TO-3P (MT-100): 0.686 to 0.882 N•m (7 to 9 kgf•cm).
• Diameter of Heatsink Hole: < 4 mm. The defl ection of the press mold when making the hole may cause the case material
to crack at the joint with the heatsink. Please pay special attention for this effect.
Soldering
• When soldering the products, please be sure to minimize the working time, within the following limits:
260±5°C 10 s
350±5°C 3 s
• Soldering iron should be at a distance of at least 1.5 mm from the body of the products
Electrostatic Discharge
• When handling the products, operator must be grounded. Grounded wrist straps worn should have at least 1 MΩ
of resistance to ground to prevent shock hazard.
• Workbenches where the products are handled should be grounded and be provided with conductive table and
floor mats.
• When using measuring equipment such as a curve tracer, the equipment should be grounded.
• When soldering the products, the head of soldering irons or the solder bath must be grounded in other to prevent
leak voltages generated by them from being applied to the products.
• The products should always be stored and transported in our shipping containers or conductive containers, or be
wrapped in aluminum foil.
