Product details
Overview
TIP116G from onsemi is a PNP silicon Darlington power transistor in TO-220AB package, rated for 80 VCEO(sus), 2.0 A continuous collector current, and 50 W power dissipation at TC = 25°C. It features monolithic construction with built-in base-emitter shunt resistors, high DC current gain (hFE = 2500 typ. @ IC = 1.0 A), and low VCE(sat) ≤ 2.5 V @ IC = 2.0 A, IB = 8.0 mA - used in linear regulators, motor drivers, and relay interface circuits.
For engineers reviewing the TIP116G datasheet, pinout, applications, or equivalent options, key selection considerations include its 80 V sustaining voltage rating, thermal resistance RJC = 2.5 °C/W, complementary pairing with TIP111G/TIP112G, and suitability for low-speed switching and medium-power amplification where high input impedance and low drive current are required.
Technical Context
The TIP116G implements a monolithic Darlington pair with integrated ~8.0 kΩ base-emitter shunt resistors, enabling simplified biasing and improved turn-off behavior. Its safe operating area (SOA) is limited by secondary breakdown at high VCE and thermally at high case temperatures, with derating to 0.4 W/°C above 25°C when mounted on heatsink.
It operates as a PNP power switch with VEB = 5.0 V maximum, IB = 50 mA max, and exhibits Cob = 200 pF @ VCB = 10 V. Small-signal current gain hfe = 25 min @ IC = 0.75 A, f = 1.0 MHz confirms usable bandwidth for audio and control-frequency switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO(sus) | 80 V min - supports operation up to 80 V supply rails without breakdown under sustained load conditions |
| IC (continuous) | 2.0 A - delivers medium-power output suitable for driving solenoids, fans, and small motors |
| PD @ TC = 25°C | 50 W - requires heatsinking for full-power operation; derates linearly at 0.4 W/°C above 25°C |
| hFE | 2500 typ. @ IC = 1.0 A - enables low-base-drive-current control, reducing driver stage complexity |
| VCE(sat) | ≤ 2.5 V @ IC = 2.0 A, IB = 8.0 mA - limits conduction loss to ≤5 W at full current, critical for thermal management |
| RJC | 2.5 °C/W - defines minimum thermal path resistance from junction to case; dictates heatsink sizing requirements |
| Cob | 200 pF @ VCB = 10 V - impacts switching speed and high-frequency stability in amplifier designs |
Pinout & Package
Package: TO-220AB (Case 221A), 4-pin outline with pins 1–4 arranged vertically; pin 1 = Base, pin 2 = Collector, pin 3 = Emitter, pin 4 = Collector (dual-collector configuration).

| 3 | Emitter | Power return path; common emitter connection for Darlington pair; mounted to tab for thermal conduction |
| 4 | Collector | Second collector terminal - paralleled with pin 2 to reduce on-resistance and improve thermal distribution |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP Darlington power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD117G | TO-252 (DPAK) surface-mount package; same 80 V/2 A rating but lower PD = 35 W; RJC = 3.6 °C/W | Designed for space-constrained PCBs; unsuitable for >25 W continuous dissipation without aggressive copper pour | Select when board area is constrained and thermal budget allows reduced power handling |
| TIP127 | Through-hole TO-220; 100 V VCEO(sus), same 2 A/50 W rating; no Pb-free marking; discontinued per onsemi documentation | Higher voltage margin for 72 V battery systems; legacy part with uncertain long-term availability | Select only for legacy redesigns requiring exact form-fit-function replacement of obsolete stock |
Compared with MJD117G and TIP127, the TIP116G offers optimal balance of through-hole manufacturability, 50 W thermal capability, and RoHS-compliant Pb-free packaging - making it preferred for new industrial control designs requiring reliability and supply continuity.

FAQ
What is the maximum collector-emitter sustaining voltage for the TIP116G?
The TIP116G has a minimum collector-emitter sustaining voltage VCEO(sus) of 80 Vdc at IC = 30 mAdc and IB = 0. This rating is confirmed in the "OFF CHARACTERISTICS" table of the official onsemi datasheet (Rev. 9, June 2024) and distinguishes it from the 60 V TIP115G and 100 V TIP117G variants. The 80 V rating makes the TIP116G suitable for 48 V nominal systems with transient margin.
Does the TIP116G have built-in base-emitter resistors?
Yes, the TIP116G features monolithic construction with built-in base-emitter shunt resistors (~8.0 kΩ each), as explicitly stated in the "Features" section and shown in Figure 1 of the onsemi datasheet. These resistors provide automatic turn-off biasing, eliminating the need for external pull-down components and improving switching reliability in microcontroller-driven applications using the TIP116G.
What is the thermal resistance junction-to-case (RJC) for the TIP116G?
The TIP116G has a maximum thermal resistance RJC of 2.5 °C/W, specified in the "THERMAL CHARACTERISTICS" table of the onsemi datasheet. This value is measured under standard mounting conditions with the TO-220AB tab attached to an infinite heatsink and is critical for calculating junction temperature rise when designing heatsinks for the TIP116G in high-power applications.
Can the TIP116G be used as a direct replacement for the TIP127?
No - the TIP116G is not a direct replacement for the TIP127. While both are PNP Darlington transistors in TO-220 packages, the TIP127 has a higher 100 V VCEO(sus) rating and is marked as discontinued by onsemi. The TIP116G's 80 V rating and Pb-free G-suffix designation mean system-level validation is required before substitution; voltage margin, thermal performance, and RoHS compliance must be reconfirmed for the TIP116G in any TIP127-based design.
What are the pin assignments for the TIP116G in TO-220AB package?
The TIP116G uses Style 1 pinout per the mechanical drawing on page 8 of the datasheet: Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector (dual-collector configuration). Pins 2 and 4 are internally connected and intended for parallel current handling and improved thermal conduction - a key layout consideration when routing the TIP116G on PCBs or attaching heatsinks.
