TIP136 PNP Transistor Pinout Datasheet

Introduction

The TIP136 PNP transistor is a high-power Darlington transistor designed for use in power switching, audio amplifier circuits, and motor control applications. With its ability to handle high collector current (up to 8A) and withstand a collector-emitter voltage of up to 80V, the TIP136 is highly reliable in circuits that demand high efficiency and stability. Being a Darlington pair, it provides extremely high current gain (hFE ≥ 1000), making it an excellent choice for applications where a small input current must control large output currents.

This transistor is housed in the TO-220 package, which provides excellent heat dissipation, enabling it to operate under demanding conditions with proper heatsinking. The TIP136 is widely used in linear power amplifiers, switching regulators, and high-current driver circuits due to its durability and robust performance. It is suitable for use in both industrial and consumer electronic devices.

TIP136 PNP Transistor

When compared to its family members, the TIP135 (60V rating) and TIP137 (100V rating), the TIP136 offers a balanced voltage rating of 80V, making it ideal for medium-voltage power circuits. Its complementary NPN counterpart, the TIP135, can be paired with it to build push-pull amplifier stages for high-quality audio or efficient power switching applications.

Equivalent Transistors of TIP136

• TIP135 (NPN, complementary)
• TIP137 (higher voltage PNP, 100V)
• BDW94C (PNP Darlington, similar ratings)
• MJ2955 (PNP power transistor, non-Darlington alternative)
• TIP125 / TIP126 / TIP127 series (PNP Darlington family with different ratings)

(Pin configuration of some transistors mentioned above may different from TIP136).

Comparison of TIP135 vs TIP136 vs TIP137

• TIP135 is the lowest-voltage version (60V), making it best suited for low-voltage power amplifier stages, LED drivers, and motor controllers.
• TIP136 offers a medium range (80V), providing a balance between voltage handling and power applications.
• TIP137 is the highest voltage (100V) device in the series, designed for high-power audio amplifiers, industrial drivers, and high-side switching where more voltage margin is needed.
• All three have the same current rating (8A continuous, 12A peak) and high gain (≥1000), so the main difference lies in voltage handling capability which is 60V, 80V & 100V respectively.
