Product details

Overview

TIP36CW from STMicroelectronics is a complementary PNP power bipolar junction transistor (BJT) designed for high-current linear and switching applications, featuring 100 V V_CEO, 25 A continuous collector current, 125 W total dissipation at T_case = 25 °C, and low 1.8 V V_CE(sat) at I_C = 15 A / I_B = 1.5 A - used in audio amplifier output stages and DC motor drive half-bridges.

For engineers reviewing the TIP36CW datasheet, TIP36CW pinout, TIP36CW application, or TIP36CW equivalent, key selection considerations include its TO-247 package thermal resistance (R_thj-case = 1 °C/W), guaranteed h_FE ≥ 10 at I_C = 15 A, and compatibility with TIP35CW in push-pull configurations requiring matched complementary gain and saturation behavior.

Technical Context

The TIP36CW is a planar silicon PNP BJT with "base island" layout, delivering high DC current gain (h_FE = 10–50) across 1.5–15 A collector current range while maintaining low saturation voltage. Its rated V_CEO = 100 V and V_CBO = 100 V support operation in medium-voltage power amplifiers and industrial control circuits.

Thermal design is enabled by R_thj-case = 1 °C/W and maximum junction temperature of 150 °C, allowing stable 125 W dissipation with adequate heatsinking. It is specified for operation up to 3 MHz f_T under I_C = 1 A / V_CE = 10 V conditions, confirming suitability for audio-frequency switching and linear amplification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	100 V - supports operation in 80 V rail audio amplifiers and 48 V industrial motor drives without breakdown.
I_C (continuous)	25 A - enables direct drive of high-power loudspeakers or solenoid loads without external current boosting.
V_CE(sat)	1.8 V @ I_C=15 A, I_B=1.5 A - minimizes conduction loss and heat generation in Class AB output stages.
h_FE	10 min @ I_C=15 A - ensures predictable base drive requirements and stable biasing in linear applications.
R_thj-case	1 °C/W - allows precise thermal modeling when mounted on standard TO-247-compatible heatsinks.
f_T	3 MHz @ I_C=1 A, V_CE=10 V - confirms usable bandwidth for full-range audio signal handling and PWM switching up to ~200 kHz.

Pinout & Package

Package: TO-247 - three-terminal through-hole power package with isolated metal tab, optimized for mechanical robustness and thermal transfer via screw-mount heatsink interface.

Pin/Terminal	Circuit Role	Design Meaning
1 (Tab)	Collector	Electrically connected to metal case; must be insulated from heatsink unless circuit common is collector-referenced.
2	Base	Control terminal; requires 1.5–5 A peak base drive for full 25 A collector conduction.
3	Emitter	Current return path; polarity inverted vs. NPN - connects to positive supply rail in high-side switch configurations.

Key Features

Feature	Design Value
Low V_CE(sat)	1.8 V at 15 A enables <1.5 W conduction loss per device in Class AB audio outputs.
High h_FE consistency	Min 10 at 15 A ensures stable bias point across production lots and temperature ranges.
TO-247 thermal performance	R_thj-case = 1 °C/W supports 125 W dissipation with ≤125 °C junction rise above heatsink.
ECOPACK® compliance	Lead-free second-level interconnect meets RoHS and JEDEC JESD97 environmental standards.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD47	TO-220 package, R_thj-case = 2.5 °C/W, P_tot = 50 W, V_CEO = 100 V, I_C = 10 A	Lower power handling; suitable only for ≤30 W amplifiers or <10 A loads.	Select when board space or cost constraints preclude TO-247 mounting and thermal budget permits derating.
BD912	TO-126 package, R_thj-case = 5 °C/W, P_tot = 12.5 W, V_CEO = 80 V, I_C = 12 A	Reduced voltage and thermal capability; limited to low-voltage, low-power switching.	Choose only for legacy designs where footprint compatibility with BD911/BD912 pairs is required.

Compared with MJD47 and BD912, the TIP36CW delivers 2.5× higher power dissipation and 2.5× lower thermal resistance, enabling higher output power in compact heatsink footprints - critical for audio amplifiers and motor drivers where thermal margin directly impacts reliability.

FAQ

Is TIP36CW pin-compatible with TIP35CW?

Yes - both devices use identical TO-247 packages with collector (tab), base (pin 2), and emitter (pin 3) assignments. Their complementary polarity (PNP vs. NPN) and matched V_CEO, I_C, and h_FE ranges enable direct pairing in push-pull amplifier and H-bridge circuits without layout changes.

What is the maximum safe operating area (SOA) limit at 25 °C case temperature?

At T_case = 25 °C, the TIP36CW's SOA is defined by its 100 V V_CEO, 25 A I_C, and 125 W P_tot limits. The device supports DC operation up to 100 V × 1.25 A or 50 V × 2.5 A without secondary breakdown, per Figure 7 in the official ST datasheet (Rev 4, Sep 2008).

Can TIP36CW be used in switching power supplies?

It can operate in low-frequency (<100 kHz) hard-switched SMPS topologies, but its 3 MHz f_T and lack of specified switching times make it less optimal than modern MOSFETs or RF BJTs. Use is appropriate only where linear operation, ruggedness, or legacy design continuity outweighs efficiency and speed requirements.

Does TIP36CW require a base resistor in linear amplifier applications?

Yes - a base resistor is mandatory to limit I_B and prevent thermal runaway. For 15 A I_C operation, a 1.5–2.2 Ω resistor (1–2 W) between driver and base ensures I_B ≈ 1.5–2.5 A, aligning with the h_FE and V_BE(on) specifications in Table 4.
