Product details

Overview

2N6052G from onsemi is a complementary Darlington silicon power transistor in TO-204AA (TO-3) metal package, rated for 100 V_CEO(sus), 12 A continuous collector current, and 150 W power dissipation at T_C = 25°C. It features monolithic construction with built-in base-emitter shunt resistors and delivers h_FE = 750 (min) at I_C = 6.0 A, enabling high-gain low-frequency switching in industrial motor controls.

For engineers reviewing the 2N6052G datasheet, pinout, applications, or equivalent options, this device is selected for robust linear amplification and DC/low-frequency switching where high DC current gain, thermal stability up to +200°C junction temperature, and rugged TO-3 mechanical reliability are required.

Technical Context

The 2N6052G implements a monolithic complementary Darlington pair with integrated base-emitter shunt resistors to ensure predictable turn-off behavior and reduce external bias complexity. Its V_CEO(sus) = 100 V (min) and I_C = 12 A rating support operation in high-voltage, medium-current switching nodes such as relay drivers and power supply output stages.

Thermal design is enabled by R_JC = 1.17°C/W max and a wide operating temperature range of −65°C to +200°C. The device exhibits V_CE(sat) ≤ 2.0 V at I_C = 6.0 A / I_B = 24 mA and V_BE(sat) ≤ 4.0 V at I_C = 12 A / I_B = 120 mA - parameters critical for minimizing conduction loss in saturated-switching applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO(sus)	100 V min - sustains 100 V across C–E at I_C = 100 mA with zero base drive, defining safe blocking capability in relay and solenoid drivers.
I_C Continuous	12 A - supports sustained load currents up to 12 A with heatsink, suitable for industrial actuator control without derating below 25°C case temperature.
P_D @ T_C = 25°C	150 W - enables high-power linear or switching operation when mounted on a low-thermal-resistance heatsink.
h_FE @ I_C = 6 A	750 min - provides high DC current gain to minimize required base drive current, reducing driver stage complexity and power loss.
R_JC	1.17°C/W max - allows precise junction temperature estimation from case temperature measurement, essential for thermal margin validation.
T_J Range	−65°C to +200°C - ensures operational reliability in extreme environments including furnace controls and under-hood automotive subsystems.

Pinout & Package

2N6052G uses the TO-204AA (TO-3) metal can package with collector connected to the case. Pin 1 is Base, Pin 2 is Emitter; the metal case serves as the Collector terminal. This configuration requires electrical isolation of the case from heatsink unless collector is referenced to chassis ground.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Base	Control input requiring current-limited drive; internal shunt resistor aids turn-off but does not eliminate need for active base pull-down in high-speed switching.
Pin 2	Emitter	Reference node for base-emitter bias; polarity defines NPN/PNP complement - 2N6052G is the NPN half of a complementary pair.
Metal Case	Collector	High-current output terminal; electrically tied to collector; must be insulated from mounting surface unless circuit topology permits direct chassis connection.

Key Features

Feature	Design Value
Monolithic Darlington construction	Integrates driver and output transistors on one die, eliminating interconnect parasitics and ensuring matched thermal tracking between stages.
Built-in base-emitter shunt resistors	Reduces external component count for reliable turn-off; prevents leakage-induced false turn-on in high-impedance base drive circuits.
100 V sustaining voltage	Supports operation in 48 V and 72 V industrial bus systems with margin against inductive kickback in relay/solenoid loads.
Pb-free TO-3 package	Complies with RoHS Directive 2011/65/EU; compatible with standard SnPb and lead-free solder reflow profiles per J-STD-020.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-gain complementary power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2N6059G	Same TO-3 package, higher V_CEO(sus) = 120 V (min), lower h_FE = 500 (min) at I_C = 6 A.	Better suited for 120 V AC line-connected circuits requiring higher blocking voltage; less gain demands stronger base drive.	Select 2N6059G when V_CEO margin >20 V is mandatory and base drive capability exceeds 40 mA.
MJ15003	TO-3 package, 120 V V_CEO, 20 A I_C, h_FE = 20–70 (typ), no internal shunt resistors.	Higher current rating but significantly lower gain; requires external turn-off circuitry and careful SOA management.	Choose MJ15003 only when peak current >12 A is required and system-level base drive and protection circuitry is already designed.

Compared with 2N6052G, 2N6059G offers higher voltage headroom at reduced DC gain, while MJ15003 trades gain and integration for raw current capacity - making 2N6052G optimal for gain-sensitive, thermally constrained 100 V-class switching where simplicity and reliability are prioritized.

FAQ

What is the maximum continuous collector current rating for the 2N6052G?

The 2N6052G is rated for 12 A continuous collector current (I_C) at case temperature T_C = 25°C. Derating is required above 25°C at 0.857 W/°C, and actual usable current depends on heatsink thermal resistance and ambient conditions. The device also supports 20 A peak current under pulsed conditions per its maximum ratings table.

Does the 2N6052G have built-in base-emitter resistors, and how do they affect circuit design?

Yes, the 2N6052G features monolithic construction with built-in base-emitter shunt resistors. These resistors provide a defined discharge path for stored base charge, improving turn-off consistency and reducing susceptibility to leakage-induced false turn-on. However, they do not eliminate the need for active base pull-down in high-speed switching applications - external base resistors may still be required for precise timing control.

What is the safe operating area (SOA) limitation for the 2N6052G at DC or low-frequency operation?

The 2N6052G's DC safe operating area is bounded by thermal limits (150 W at T_C = 25°C) and second breakdown. At V_CE = 50 V, the maximum sustainable I_C is approximately 2.5 A under DC conditions per Figure 5. Operation beyond these boundaries risks thermal runaway or localized junction failure, especially without adequate heatsinking or current limiting.

Can the 2N6052G be used in complementary pairs, and which part is its PNP counterpart?

Yes, the 2N6052G is the NPN half of a complementary Darlington pair. Its designated PNP counterpart is the 2N6051G, which shares identical package (TO-3), voltage rating (100 V V_CEO(sus)), current rating (12 A), and thermal characteristics. Both devices are optimized for matched performance in push-pull amplifier and H-bridge output stages.

Is the 2N6052G RoHS-compliant, and what does the 'G' suffix indicate?

Yes, the 2N6052G is RoHS-compliant. The 'G' suffix explicitly denotes a Pb-free (lead-free) version per onsemi's packaging nomenclature, confirming compliance with EU Directive 2011/65/EU. This applies to both die attach and external terminations, and the device is qualified for standard lead-free reflow profiles.
