Product details

Overview

2STC5200 from STMicroelectronics is a high-power NPN epitaxial planar bipolar transistor using BiT-LA technology for linear audio amplification, featuring V_CEO > 230 V, I_C = 15 A, P_tot = 150 W at T_C = 25°C, f_T = 30 MHz, and R_thJ-case = 0.83°C/W - deployed in high-fidelity stereo power amplifier output stages.

For engineers reviewing the 2STC5200 datasheet, 2STC5200 pinout, 2STC5200 application, or 2STC5200 equivalent, key selection considerations include safe operating area (SOA) compliance at high V_CE, gain linearity under large-signal swing, thermal derating above 25°C case temperature, and complementary pairing with 2STA1943 in push-pull configurations.

Technical Context

This device operates as a linear-output-stage switching and amplification element in Class AB audio power amplifiers. Its BiT-LA process ensures improved h_FE linearity across I_C = 1–7 A and low V_CE(sat) = 3 V at I_C = 8 A / I_B = 800 mA.

Designed for discrete high-current output stages, it supports resistive-load switching with t_on = 0.24 µs, t_s = 4.7 µs, and t_f = 0.6 µs at V_CC = 60 V, I_C = 5 A, and symmetric ±0.5 A base drive - enabling fast transient response without secondary breakdown in protected SOA regions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	>230 V - supports rail voltages up to ±100 V in dual-supply audio amplifiers without breakdown
I_C	15 A continuous - delivers ≥100 W RMS into 4 Ω loads with proper heatsinking
P_tot	150 W at T_C = 25°C - requires thermal interface & heatsink design with R_thJ-amb < 0.8°C/W for full power operation
f_T	30 MHz - enables stable wideband feedback loop compensation up to 500 kHz open-loop bandwidth
h_FE	80–160 at I_C = 1 A; 35–80 at I_C = 7 A - maintains predictable bias current sharing in parallel-output configurations
R_thJ-case	0.83°C/W - defines minimum thermal resistance path from junction to heatsink mounting surface
t_s	4.7 µs - limits storage charge accumulation during turn-off, reducing crossover distortion in Class AB

Pinout & Package

Supplied in TO-264 (ISOWATT218™-like) package: isolated metal tab, 3-pin vertical mount, lead-free ECOPACK® compliant. Mounting hole ØP = 3.55–3.65 mm; case height L = 19.5–20.5 mm; width E = 19.8–20.2 mm.

Pin/Terminal	Circuit Role	Design Meaning
1 (Tab)	Collector (electrically connected to case)	Must be electrically isolated from heatsink unless circuit design intentionally references collector to chassis ground
2	Base	Low-impedance drive node requiring ~800 mA peak for full saturation; sensitive to PCB trace inductance
3	Emitter	Main current return path; connects to emitter resistor network or global ground plane with minimal inductance

Key Features

Feature	Design Value
BiT-LA process technology	Delivers measured h_FE linearity over I_C = 0.1–10 A, reducing harmonic distortion in Class AB output stages
Complementary pairing with 2STA1943	Enables matched push-pull output stage with symmetrical V_CEO, I_C, and f_T specs for balanced clipping behavior
High SOA rating	Rated for 100 V × 10 A DC operation at T_C = 25°C - supports unregulated rail designs without forced-air cooling
Fast storage time (t_s)	4.7 µs enables clean turn-off in high-slew-rate amplifiers, minimizing switching-induced intermodulation distortion

Applications

Hi-Fi Stereo Power Amplifier

Professional PA Output Stage

Use Scenario: Discrete Class AB output stage delivering 100–200 W per channel into 4–8 Ω loads with THD < 0.05% at 1 kHz.

IC Role / Device Role / Timing Role: Primary high-current output transistor handling peak currents up to 25 A in push-pull configuration with 2STA1943.

Use Value: High V_CEO and SOA allow operation from ±85 V rails without snubbers; BiT-LA linearity reduces third-harmonic distortion by ≥8 dB vs. standard planar transistors.

Use Scenario: 500 W+ touring-grade power amplifier output module driving low-Z line arrays with dynamic headroom requirements.

IC Role / Device Role / Timing Role: Parallel-connected output device (≥4 per rail) managing sustained 20 A average current and 40 A peaks under program material.

Use Value: 0.83°C/W R_thJ-case enables compact heatsink integration; low t_s prevents thermal runaway during clipped transients.

Studio Monitor Amplifier

Active Subwoofer Driver

Use Scenario: Near-field studio monitor with 60 W/channel output, optimized for flat frequency response and low noise floor.

IC Role / Device Role / Timing Role: Linear output device biased in Class AB with local feedback; operates at 60–70% of max I_C for thermal stability.

Use Value: Tight h_FE spread (80–160) simplifies matched pair selection; low V_CE(sat) minimizes quiescent power loss and heatsink size.

Use Scenario: Sealed or ported active subwoofer amplifier delivering 300 W into 2–4 Ω loads with extended low-frequency headroom.

IC Role / Device Role / Timing Role: Single-ended output transistor in high-current, low-impedance driver stage handling 30 A peak currents below 100 Hz.

Use Value: 230 V V_CEO supports ±100 V rails needed for 300 W into 4 Ω; robust SOA prevents failure during bass-heavy program peaks.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-power linear amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJE15030G	V_CEO = 200 V (lower), f_T = 20 MHz (slower), R_thJ-case = 1.0°C/W (higher)	Limited to ±80 V rails; reduced bandwidth margin for ultrasonic compensation	Select when cost sensitivity outweighs rail voltage headroom and thermal performance needs
BDW83C	I_C = 12 A (lower), P_tot = 125 W, no published SOA curve	Not recommended for sustained >100 W operation or parallel configurations without derating	Acceptable only for legacy repair or non-critical consumer-grade amplifiers with conservative thermal design

Compared with MJE15030G and BDW83C, the 2STC5200 provides superior rail voltage margin, thermal efficiency, and documented SOA - making it the preferred choice for new high-fidelity or professional audio amplifier designs requiring reliability at full rated power.

FAQ

Is the 2STC5200 RoHS-compliant and lead-free?

Yes. The 2STC5200 is manufactured in ST's ECOPACK® package with lead-free second-level interconnect, compliant with RoHS Directive 2011/65/EU. The inner box label and package marking indicate the JEDEC JESD97-defined eco-category, and soldering profiles follow Pb-free reflow standards.

Can the 2STC5200 be used in parallel configurations?

Yes - its BiT-LA process ensures tight h_FE consistency and low thermal resistance (0.83°C/W), enabling stable current sharing in parallel output stages. Use individual emitter resistors (0.1–0.22 Ω) and matched base drive to prevent thermal runaway.

What is the maximum safe operating voltage for 2STC5200 in Class AB amplifiers?

The absolute maximum V_CEO is 230 V, but for reliable Class AB operation with safety margin, ST recommends limiting V_CC to ≤±100 V (200 V total supply). This aligns with the published SOA curve and avoids secondary breakdown under reactive loads.

Does the 2STC5200 require a specific base drive topology?

It performs best with low-impedance, current-limited base drive capable of delivering ≥800 mA peak. Avoid high-impedance voltage drive; use complementary Darlington or MOSFET-based drivers to minimize t_s-related distortion and ensure clean turn-on/turn-off transitions.
