Product details

Overview

MJW21196 from onsemi is an NPN silicon power transistor designed for high-fidelity audio output stages, disk head positioners, and linear amplifier applications. It features a 250 V_CEO, 16 A continuous collector current, 200 W total power dissipation at T_C = 25°C, Perforated Emitter technology, and a minimum DC current gain (h_FE) of 20 at I_C = 8 A.

For engineers reviewing the MJW21196 datasheet, pinout, applications, or equivalent options, key selection criteria include safe operating area (SOA) at 2.25 A/80 V for 1 second, THD characterization down to 0.08% in matched-pair configurations, thermal resistance R_JC = 0.7°C/W, and TO-247 package compatibility with high-power heatsinking requirements.

Technical Context

The MJW21196 operates as a linear-mode NPN bipolar junction transistor optimized for analog signal fidelity rather than switching efficiency. Its Perforated Emitter construction improves thermal stability and gain linearity under high-current bias, while its SOA curve supports sustained operation up to 80 V and 2.25 A for non-repetitive pulses.

Electrical behavior is characterized across temperature (−65°C to +150°C), with h_FE maintained ≥8 at I_C = 16 A and V_CE = 5 V, V_CE(sat) ≤ 3 V at I_C = 16 A/I_B = 3.2 A, and f_T = 4 MHz at I_C = 1 A/V_CE = 10 V - confirming suitability for audio-frequency amplification and precision linear control.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	250 Vdc - maximum collector-emitter voltage before breakdown under open-base conditions; defines rail voltage limit in Class-AB audio output stages.
I_C (continuous)	16 Adc - continuous collector current rating; sets thermal design baseline for heatsink sizing at 200 W dissipation.
h_FE min	20 @ I_C = 8 A - guaranteed DC current gain ensures stable biasing in emitter-follower or common-emitter linear amplifiers.
R_JC	0.7 °C/W - low junction-to-case thermal resistance enables efficient heat transfer to external heatsinks in high-power audio modules.
THD	0.08% (matched pair) - measured at 28.3 V_RMS, 1 kHz, 100 W load; confirms low distortion performance in high-end audio output circuits.
f_T	4 MHz - current-gain bandwidth product supports full-audio-spectrum amplification without phase degradation.
C_ob	500 pF - output capacitance at V_CB = 10 V; impacts high-frequency stability and compensation network design in feedback amplifiers.

Pinout & Package

Package: TO-247 (Case 340L), isolated collector tab, Pb-free option available as MJW21196G. Mounting requires insulated hardware due to electrically active collector tab.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal for forward-biased BJT operation; requires current-limited drive (I_B ≤ 5.0 Adc continuous) to avoid thermal runaway.
2	Collector	Main high-current output terminal; electrically connected to metal tab - must be insulated from heatsink unless circuit ground reference permits.
3	Emitte	Power return path; carries full load current in common-emitter configuration; connects to output node in emitter-follower designs.

Key Features

Feature	Design Value
Perforated Emitter technology	Enhances thermal uniformity and gain linearity under high-current, high-temperature operation - critical for low-distortion audio amplification.
High SOA (2.25 A / 80 V / 1 s)	Enables robust transient handling in unprotected linear output stages without secondary breakdown during clipping or overload events.
Total Harmonic Distortion characterization	Validated THD ≤ 0.08% in matched-pair configuration - allows precise complementary symmetry in push-pull amplifier designs.
h_FE ≥ 20 @ 8 A	Ensures predictable base drive requirements and stable quiescent current setting in Class-AB bias networks.

2SC5200	V_CEO = 230 V, I_C = 15 A, h_FE ≥ 80 @ 8 A, R_JC = 0.8°C/W, no THD characterization	Higher h_FE reduces base drive complexity but lacks THD validation and SOA data at 80 V	Select when high DC gain and cost sensitivity outweigh THD and SOA verification needs.
MJE15034	V_CEO = 250 V, I_C = 8 A, h_FE ≥ 20 @ 4 A, R_JC = 1.5°C/W, SOA rated to 1.5 A/80 V	Lower current and thermal capability limits use to <100 W applications; no Perforated Emitter	Select for space-constrained designs where 8 A suffices and TO-220 footprint is preferred.

FAQ

What is the maximum continuous collector current rating for the MJW21196?

The MJW21196 has a maximum continuous collector current rating of 16 A at T_C = 25°C. This rating assumes proper heatsinking and derating per the 1.43 W/°C thermal derating curve above 25°C. Operation beyond this current without thermal mitigation risks exceeding the 150°C maximum junction temperature and triggering secondary breakdown.

Does the MJW21196 have a Pb-free version, and how is it marked?

Yes, the Pb-free version is designated MJW21196G and uses the same TO-247 package. It is marked with a "G" suffix in the date code (e.g., AYWWG), where "G" indicates compliance with RoHS Directive 2011/65/EU. The electrical and thermal specifications are identical to the standard MJW21196.

What does "Perforated Emitter technology" mean for the MJW21196?

Perforated Emitter technology in the MJW21196 refers to a proprietary emitter geometry that improves current density uniformity and thermal distribution across the die. This results in enhanced gain linearity, reduced thermal runaway risk, and improved SOA performance - especially critical in high-power linear amplifier applications where localized heating degrades fidelity.

Can the MJW21196 be used in a complementary pair with the MJW21195?

Yes, the MJW21196 (NPN) is explicitly designed as a complementary pair with the MJW21195 (PNP). Both share identical TO-247 packaging, matching SOA curves, Perforated Emitter construction, and THD characterization - enabling symmetrical push-pull output stages with tightly matched gain and thermal behavior.

What is the safe operating area (SOA) limit for the MJW21196 at 80 V?

The MJW21196 is rated for 2.25 A at 80 V for 1 second in non-repetitive operation, as defined in the SOA curve (Figure 14). This rating assumes T_J(pk) ≤ 150°C and accounts for both thermal and secondary breakdown limits. Continuous operation at this voltage requires significant derating based on case temperature and heatsink performance.
