Product details

Overview

TIP100G from onsemi is an NPN silicon Darlington power transistor in TO-220AB package, rated for 60 V_CEO(sus), 8 A continuous collector current, and 80 W power dissipation at T_C = 25°C. It features monolithic construction with built-in base-emitter shunt resistors, typical DC current gain (h_FE) of 2500 at I_C = 4.0 A, and V_CE(sat) ≤ 2.0 V at I_C = 3.0 A - designed for medium-power linear amplification and low-speed switching in industrial control and relay driver circuits.

For engineers reviewing the TIP100G datasheet, pinout, applications, or equivalent options, key selection considerations include its 60 V sustaining voltage rating, thermal resistance (R_JC = 1.56 °C/W), Darlington input impedance, built-in base shunt resistors enabling simplified drive, and Pb-free RoHS-compliant TO-220AB packaging suitable for through-hole mounting in high-reliability power stages.

Technical Context

The TIP100G implements a monolithic Darlington pair with integrated ~8.0 kΩ base-emitter shunt resistors, eliminating external bias network requirements. Its safe operating area (SOA) is defined by second-breakdown limits up to 100 V and thermally limited dissipation at case temperatures above 25°C, with transient thermal response characterized via normalized Z_JC(t) curves.

Electrical behavior is specified under DC and pulsed conditions: V_CEO(sus) ≥ 60 V at I_C = 30 mA, h_FE = 1000–20,000 over I_C = 3–8 A, and switching times (t_d, t_r, t_s, t_f) measured with I_C/I_B = 250 and V_CC = 30 V using fast-recovery diode test circuitry per Figure 3.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO(sus)	60 V min - sustains 60 V collector-emitter voltage at 30 mA leakage before breakdown, defining maximum DC supply rail compatibility.
I_C Continuous	8.0 A - supports sustained load currents up to 8 A with heatsinking at T_C = 25°C, critical for relay coil and motor driver sizing.
P_D @ T_C = 25°C	80 W - total junction-to-case power dissipation limit; requires thermal interface and heatsink design based on R_JC = 1.56 °C/W.
h_FE	1000–20,000 - wide DC current gain range enables low-base-drive-current operation (e.g., 6 mA drives 3 A output), reducing MCU GPIO loading.
V_CE(sat)	≤2.0 V @ I_C = 3.0 A, I_B = 6.0 mA - low saturation voltage minimizes conduction loss and heat generation in switching applications.
R_JC	1.56 °C/W - junction-to-case thermal resistance determines minimum heatsink requirement for target junction temperature.

Pinout & Package

Package: TO-220AB (Case 221A, Style 1), 3-terminal plastic power package with metal tab electrically connected to collector; dimensions 10.10 × 15.12 × 4.45 mm, 2.54 mm lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input node; internally shunted to emitter via ~8.0 kΩ resistor - enables self-biasing and prevents spurious turn-on.
2	Collector	Main power input terminal; electrically tied to metal tab - must be isolated from heatsink unless common-collector configuration is intended.
3	Emitter	Power output/reference node; provides low-impedance return path for load current and sets emitter-follower reference potential.
4	Collector	Second collector connection - redundant terminal for enhanced current handling and mechanical stability; electrically identical to Pin 2.

Key Features

Feature	Design Value
Monolithic Darlington Pair	Integrates driver and output transistors on single die - delivers high h_FE without external cascading, simplifying PCB layout.
Built-in Base-Emitter Shunt Resistors	~8.0 kΩ internal resistors ensure reliable turn-off and eliminate need for external pull-downs in microcontroller-driven switches.
60 V Sustaining Voltage Rating	V_CEO(sus) ≥ 60 V allows direct use with 48 V industrial buses and 24 V systems with margin for inductive kickback.
Pb-Free & RoHS Compliant	G-suffix indicates lead-free termination and full compliance with EU RoHS Directive 2011/65/EU - required for commercial and industrial shipments.
TO-220AB Mechanical Robustness	Plastic package with metal tab withstands >10 kgf mounting pressure and supports >50,000 thermal cycles in industrial environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN Darlington transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD100G	Surface-mount DPAK package (TO-252), same 60 V/8 A rating but lower P_D = 30 W @ T_C = 25°C and higher R_JC = 4.2 °C/W.	Requires PCB copper pour for thermal management; unsuitable for through-hole legacy designs or high-power derating scenarios.	Select MJD100G only when space-constrained SMT assembly is mandatory and power dissipation remains below 25 W.
TIP120	Same TO-220AB package, but V_CEO(sus) = 60 V, h_FE = 1000 (min), no built-in base shunt resistors - requires external 10 kΩ pull-down.	Lacks internal turn-off assurance; susceptible to noise-induced latch-up in electrically noisy industrial cabinets without added components.	Choose TIP120 only if cost sensitivity outweighs reliability requirements and external base resistor placement is acceptable.

Compared with MJD100G and TIP120, the TIP100G uniquely combines through-hole TO-220AB robustness, built-in base shunt resistors for noise immunity, and 80 W power capability - making it optimal for industrial relay drivers and linear regulator pass elements where layout simplicity and thermal headroom are critical.

FAQ

What is the maximum collector-emitter sustaining voltage for TIP100G?

The TIP100G has a minimum collector-emitter sustaining voltage V_CEO(sus) of 60 Vdc at I_C = 30 mAdc and I_B = 0. This rating ensures reliable blocking capability in 48 V industrial systems with safety margin against inductive transients. The value is verified per onsemi datasheet Rev. 16, page 2, OFF CHARACTERISTICS table.

Does TIP100G include internal base-emitter resistors?

Yes, the TIP100G integrates monolithic base-emitter shunt resistors (~8.0 kΩ each) as confirmed in the device schematic (Figure 1) and Features section of the onsemi datasheet. These resistors provide automatic turn-off biasing, eliminating external pull-down components and improving noise immunity in PLC and motor control applications.

What is the thermal resistance from junction to case for TIP100G?

The TIP100G has a maximum thermal resistance R_JC of 1.56 °C/W, measured from junction to case surface (metal tab). This value is critical for heatsink sizing: at 80 W dissipation, the junction-to-case temperature rise would be ≤125°C - requiring careful thermal interface design to maintain T_J ≤ 150°C per datasheet limits.

Can TIP100G be used in linear regulator applications?

Yes, the TIP100G is explicitly suited for linear regulator pass elements due to its 80 W power rating at T_C = 25°C, wide SOA (Figure 6), and stable h_FE across collector current. Its low V_CE(sat) and predictable thermal behavior enable precise analog voltage regulation in bench supplies and industrial power modules.

Is TIP100G RoHS compliant and lead-free?

Yes, the "G" suffix in TIP100G denotes a Pb-free, RoHS-compliant package per onsemi's ordering information (page 7) and Features statement. It meets EU Directive 2011/65/EU requirements and uses matte tin lead finish - verified in the official datasheet revision history and packaging specifications.
