Product details
Overview
MPSW92RLRAG from onsemi is a PNP silicon high-voltage transistor rated for −300 VCEO, −500 mA continuous collector current, and 1.0 W total dissipation at TA = 25°C in TO-92 package. It delivers DC current gain (hFE) of 25–40 at −10 mA, −10 V, and supports switching applications requiring robust breakdown margin and thermal stability up to +150°C junction temperature.
For engineers reviewing the MPSW92RLRAG datasheet, pinout, applications, or equivalent options, key selection criteria include verified −300 VCEO/−300 VCBO ratings, confirmed TO-92 lead configuration (Emitter–Base–Collector), low VCE(sat) ≤ −0.5 V at −20 mA/−2 mA drive, and Pb-free compliance per ordering code suffix "RLRAG".
Technical Context
This PNP bipolar junction transistor operates with reverse-polarity biasing: emitter positive relative to base and collector. Its high-voltage capability stems from optimized epitaxial base-collector junction design, enabling stable operation under sustained −300 V blocking conditions with leakage < −0.25 A at −200 VCB.
The device exhibits fT = 50 MHz at −10 mA and −20 VCE, supporting medium-speed switching in flyback snubbers and relay drivers. Thermal resistance RJA = 125°C/W confirms suitability for natural-convection PCB mounting without heatsinking in low-duty-cycle applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −300 Vdc - Sustains full reverse voltage across collector-emitter with IB = 0, critical for HV off-state hold in power supply protection circuits. |
| IC (cont.) | −500 mAdc - Maximum continuous DC collector current; defines upper limit for steady-state load switching in discrete driver stages. |
| PD @ TA | 1.0 W - Total power dissipation at 25°C ambient; derates linearly at 8 mW/°C above 25°C, limiting usable power in enclosed environments. |
| hFE | 25–40 - DC current gain range at −10 mA/−10 V; determines required base drive current for saturation in linear or switching modes. |
| VCE(sat) | ≤ −0.5 Vdc - Collector-emitter saturation voltage at −20 mA/−2 mA; directly impacts conduction loss and thermal rise in saturated switch operation. |
| fT | 50 MHz - Current-gain bandwidth product at −10 mA/−20 V; sets upper frequency bound for small-signal amplification or fast switching. |
| RJA | 125 °C/W - Junction-to-ambient thermal resistance; used to calculate max junction temperature rise under given power and ambient conditions. |
Pinout & Package
Package: TO-92 (Case 29-10), 1 W rating, straight-lead Pb-free variant per ordering code MPSW92RLRAG. Pin assignment follows Style 17: Pin 1 = Collector, Pin 2 = Base, Pin 3 = Emitter.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Collector | Main current sink terminal; connected to negative rail or load return path in PNP high-side switching configurations. |
| 2 | Base | Control input; forward-biased with respect to emitter to turn on device; requires current-limiting resistor for safe drive. |
| 3 | Emitter | Current source terminal; typically tied to positive supply in common-emitter switching; defines reference for VBE and VCE measurements. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage blocking | −300 VCEO and −300 VCBO enable direct use in 240 VAC line-derived supplies and industrial control inputs without external voltage division. |
| Pb-free packaging | Compliant with RoHS Directive 2011/65/EU; marked "G" and microdot per generic marking diagram; suitable for environmentally regulated production. |
| Wide temperature range | −55°C to +150°C operating junction range supports deployment in automotive engine compartments and outdoor power equipment. |
| Low saturation voltage | VCE(sat) ≤ −0.5 V at −20 mA ensures < 10 mW conduction loss per switch event, reducing self-heating in repetitive pulse applications. |
| Stable gain vs. temp | hFE retains ≥25 at −55°C and +125°C (per Figure 4), enabling predictable base drive sizing across environmental extremes. |
Applications
| AC-DC Power Supply Snubber | Industrial Relay Driver |
|---|---|
|
Use Scenario: Clamping voltage spikes during MOSFET/IGBT turn-off in offline flyback converters. IC Role / Device Role / Timing Role: Discrete PNP switch absorbing transient energy into RC network; triggered by auxiliary winding voltage polarity reversal. Use Value: −300 VCEO withstands reflected primary transients without avalanche stress; TO-92 footprint allows compact placement near power stage. |
Use Scenario: Driving 24 VDC industrial relays with 50–100 mA coil current from microcontroller GPIO. IC Role / Device Role / Timing Role: High-side switch controlling relay coil return path; base driven via current-limited resistor from logic-level signal. Use Value: −500 mA IC rating exceeds typical relay coil requirements; −0.5 V VCE(sat) minimizes coil voltage drop and ensures reliable pull-in. |
| High-Voltage Signal Level Shifting | Overvoltage Protection Circuit |
|

IC Role / Device Role / Timing Role: PNP emitter-follower configured as level translator; emitter referenced to high-voltage rail, base driven by low-voltage controller. Use Value: −300 VCBO prevents breakdown between collector (tied to HV rail) and base (logic side); fT = 50 MHz supports >100 kHz signal transfer. |
Use Scenario: Crowbar circuit triggering thyristor gate when input voltage exceeds −280 V threshold. IC Role / Device Role / Timing Role: Voltage-sensing switch comparing divided input to Zener reference; conducts when overvoltage detected to fire SCR. Use Value: Low IEBO ≤ −0.1 A ensures minimal leakage-induced false triggers; wide TJ range maintains accuracy across ambient extremes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-voltage transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPSW92G | Same die, identical electrical specs, TO-92 Pb-free package but supplied in bulk (5000/unit box) instead of tape-and-reel. | No functional difference; differs only in packaging format and reel quantity (2000 vs. 5000 units). | Select MPSW92G for manual assembly or low-volume prototyping where tape-and-reel handling is unnecessary. |
| PN3906 | Lower VCEO = −40 V, lower IC = −200 mA, higher VCE(sat) ≈ −0.4 V, same TO-92 package. | Not suitable for >−60 V applications; limited to low-voltage logic interface and signal switching. | Choose PN3906 only when system voltage remains below −40 V and power dissipation is < 0.5 W. |
Compared with MPSW92RLRAG, MPSW92G offers identical performance in a different logistics format, while PN3906 provides cost-effective substitution only in low-voltage designs-neither qualifies as pin-compatible or direct replacement due to voltage/current rating mismatch.

FAQ
What is the maximum collector-emitter voltage rating for MPSW92RLRAG?
The MPSW92RLRAG has a guaranteed minimum V(BR)CEO of −300 Vdc at IC = −1.0 mAdc and IB = 0, as specified in the Absolute Maximum Ratings table. This rating is validated under pulsed test conditions (300 µs pulse width, 2% duty cycle) and applies to continuous DC operation within the recommended operating conditions. The MPSW92RLRAG must not be operated beyond this voltage to prevent irreversible junction breakdown.
Is MPSW92RLRAG RoHS compliant and what does the 'G' suffix indicate?
Yes, MPSW92RLRAG is RoHS compliant. The 'G' in the part number denotes Pb-free packaging per JEDEC J-STD-609, confirmed in the Ordering Information section and Generic Marking Diagram. The device uses matte tin lead finish and meets exemption 7a for lead in high-melting-temperature solder alloys. The MPSW92RLRAG is shipped in tape-and-reel format (2000 units/reel) with Pb-free marking visible on the package body.
What is the pin configuration for MPSW92RLRAG in the TO-92 package?
The MPSW92RLRAG uses TO-92 Style 17 pinout: Pin 1 is Collector, Pin 2 is Base, and Pin 3 is Emitter. This is explicitly defined in the Mechanical Case Outline section on page 3 of the datasheet. The MPSW92RLRAG is not compatible with Style 1 (Emitter–Base–Collector) or Style 2 (Base–Emitter–Collector); correct orientation is critical to avoid reverse-bias damage during circuit operation.
How does the DC current gain (hFE) of MPSW92RLRAG vary with collector current?
The MPSW92RLRAG exhibits hFE = 25 at IC = −1.0 mAdc, hFE = 40 at IC = −10 mAdc, and hFE = 25 again at IC = −30 mAdc (all at VCE = −10 Vdc and TA = 25°C). This non-monotonic behavior reflects peak gain near mid-range currents. For reliable design, the MPSW92RLRAG should be biased using the −10 mAdc hFE value to ensure sufficient base drive margin across temperature and unit variation.
Can MPSW92RLRAG be used in place of MPSW92 in existing designs?
Yes, MPSW92RLRAG is a direct replacement for MPSW92 in terms of electrical performance and pinout, with identical VCEO, IC, hFE, and thermal characteristics. The only differences are Pb-free construction (vs. legacy SnPb) and tape-and-reel packaging (2000 units/reel). No PCB layout changes are required, and the MPSW92RLRAG maintains full compatibility with existing footprints and solder profiles qualified for standard TO-92 components.
