onsemi 2N5883G

Overview

2N5883G from onsemi is a PNP silicon power transistor in TO-204AA (TO-3) metal package, rated for 60 V_CEO, 25 A continuous collector current, and 200 W total dissipation at T_C = 25°C. It delivers low V_CE(sat) of 1.0 V (max) at I_C = 15 A and supports high-current switching and linear amplification in industrial power stages.

For engineers reviewing the 2N5883G datasheet, pinout, applications, or equivalent options, key selection criteria include its PNP polarity, TO-3 thermal performance, 200 W power handling, and verified switching times (t_r ≤ 0.7 µs, t_s ≤ 1.0 µs) under 10 A/30 V conditions.

Technical Context

This device operates as a high-power bipolar junction transistor with fixed PNP polarity, requiring base current drive to control collector-emitter conduction. Its DC current gain h_FE ranges from 4.0 (min) at I_C = 25 A to 35 (min) at I_C = 3 A, and it exhibits f_T ≥ 4.0 MHz at I_C = 1.0 A, supporting medium-frequency switching.

Thermal design relies on direct case mounting: θ_JC = 0.875°C/W max enables stable operation up to T_J = +200°C, while safe operating area (SOA) curves define second-breakdown and thermal limits across pulse widths from single-shot to 5 ms at T_C = 25°C.

Key Specifications

Pinout & Package

2N5883G uses the TO-204AA (TO-3) metal can package with integral collector-connected case. Mounting requires electrically isolated hardware due to case-to-collector continuity. Thermal path is optimized via direct case-to-heatsink contact.

FAQ

What is the maximum junction temperature specification for the 2N5883G?

The 2N5883G has an operating junction temperature range of –65°C to +200°C. This wide rating enables use in extreme environments such as engine compartments, industrial ovens, and welding gear. Derating begins above T_C = 25°C at 1.15 W/°C, and thermal resistance from junction to case is 0.875°C/W max. Always verify actual T_J using measured case temperature and power dissipation in the final layout.

Is the 2N5883G pin-compatible with other devices in the 2N588x family?

Yes - the 2N5883G shares identical TO-204AA (TO-3) mechanical outline and pinout (Pin 1 = Base, Pin 2 = Emitter, Case = Collector) with 2N5884G, 2N5885G, and 2N5886G. However, electrical characteristics differ: 2N5883G and 2N5884G are PNP; 2N5885G and 2N5886G are NPN; and voltage ratings vary (60 V vs. 80 V). Substitution requires verifying polarity and voltage compliance.

What is the typical base-emitter on voltage for the 2N5883G at 10 A collector current?

The 2N5883G exhibits V_BE(on) = 1.5 V (typical) at I_C = 10 A and V_CE = 4.0 V, per the Electrical Characteristics table. This value reflects forward-biased base-emitter junction behavior under linear operation and informs base drive circuit design - e.g., a 5 V logic signal with 220 Ω series resistor delivers ~15.9 mA base current, sufficient for h_FE ≥ 20.

Does the 2N5883G have a documented safe operating area for repetitive pulse operation?

Yes - Figure 5 in the official 2N5883/D datasheet provides the active-region safe operating area (SOA) for single-pulse conditions, and thermal response data (Figure 4) enables calculation of repetitive pulse limits. For example, at 10% duty cycle and 5 ms on-time, the effective thermal resistance reduces allowable power based on r(t) curves. Engineers must combine SOA boundaries with transient thermal modeling to ensure second-breakdown and thermal limits are not exceeded.

How does the 2N5883G's f_T of 4.0 MHz impact its suitability for switching power supplies?

The 2N5883G's minimum f_T of 4.0 MHz supports stable operation in hard-switched power supplies up to ~1–2 MHz, assuming proper base drive strength and layout. While not optimized for MHz-range resonant topologies, it remains appropriate for 100–500 kHz flyback, forward, and push-pull converters where bipolar switching speed and ruggedness outweigh ultra-high-frequency gain. Always validate switching waveforms and losses empirically at target frequency and load.
