Product details
Overview
MPSW56RLRAG from onsemi is a PNP silicon small-signal transistor in TO-92 package, rated for −80 VCEO, −500 mA continuous collector current, and 1.0 W dissipation at TA = 25°C. It serves as a general-purpose amplifier or switch in low-power analog and digital interface circuits, including voltage-level translation and relay drivers.
For engineers reviewing the MPSW56RLRAG datasheet, pinout, applications, or equivalent options, key selection criteria include its −80 VCEO rating, hFE ≥ 50 at −250 mA, VCE(sat) ≤ −0.5 V, Pb-free TO-92 packaging, and thermal resistance of 125°C/W to ambient.
Technical Context
This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with verified DC current gain (hFE) of 50 minimum at −250 mA and −1.0 VCE. Its fT is 50 MHz under specified bias conditions, supporting audio-frequency amplification and switching up to several megahertz.
Thermal design is constrained by RJA = 125°C/W and RJC = 50°C/W, requiring heatsinking or derating above 25°C ambient. Safe operating area (SOA) curves confirm second-breakdown limits at DC and pulsed conditions, with thermal limit dominating below 1 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum reverse-biased collector-emitter voltage before breakdown; defines high-side switching headroom |
| IC (continuous) | −500 mA - Absolute maximum DC collector current; usable up to −250 mA with guaranteed hFE ≥ 50 |
| PD @ TA = 25°C | 1.0 W - Power dissipation limit without heatsink; derates 8 mW/°C above ambient |
| hFE | 50 min @ −250 mA, −1.0 VCE - Ensures reliable current amplification in linear and saturated switching modes |
| VCE(sat) | ≤ −0.5 V @ −250 mA, −10 mA IB - Low saturation voltage minimizes power loss in switching applications |
| fT | 50 MHz @ −250 mA, −5.0 VCE - Supports stable small-signal amplification up to mid-audio frequencies |
Pinout & Package
Package: TO-92 (Case 29-10), Pb-free, straight-lead configuration per Style 17 (PIN 1 = COLLECTOR, PIN 2 = BASE, PIN 3 = EMITTER).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Collector | Main current sink terminal; connects to load or supply rail in common-emitter configurations |
| 2 | Base | Control input; requires current-limited drive to achieve target IC and avoid thermal runaway |
| 3 | Emitter | Current source reference node; typically tied to ground or positive rail in PNP emitter-follower topologies |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | −80 V enables use in 48 V industrial control rails and automotive battery-supplied circuits |
| Guaranteed hFE at high IC | 50 minimum at −250 mA ensures predictable gain in medium-current switching stages |
| Low VCE(sat) | ≤ −0.5 V reduces conduction loss and self-heating in relay and LED driver applications |
| Pb-free TO-92 packaging | RoHS-compliant leadform supports automated through-hole assembly and environmental compliance |
Applications
| Industrial Relay Driver | Automotive Door Lock Control |
|---|---|
Use Scenario: Driving 12 V, 200 mA electromagnetic relays in programmable logic controllers. IC Role / Device Role / Timing Role: PNP switch configured in common-emitter mode, sinking relay coil current to ground. Use Value: −80 VCEO withstands inductive kickback; −0.5 VCE(sat) limits power dissipation to <100 mW at full load. | Use Scenario: Controlling solenoid-based door lock actuators in 12 V vehicle systems. IC Role / Device Role / Timing Role: High-side switch using emitter-follower configuration to interface microcontroller GPIO with 12 V loads.

IC Role / Device Role / Timing Role: Common-emitter amplifier biased in active region for linear voltage gain. Use Value: 50 MHz fT supports flat frequency response up to 20 kHz with adequate phase margin. | Use Scenario: Enabling/disabling auxiliary 5 V rail after main 12 V supply stabilizes in multi-rail power systems. IC Role / Device Role / Timing Role: Level-shifting enable switch controlling gate of downstream MOSFET or regulator EN pin. Use Value: −4.0 VEBO rating prevents base-emitter junction breakdown during sequencing transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPSW56RLRP | Same die, TO-92 ammo pack (non-Pb-free marking); identical electrical specs | No RoHS compliance; unsuitable for EU/China export or medical devices | Select when legacy Pb-containing assembly is permitted and cost sensitivity outweighs compliance requirements |
| BC807-40LT1G | Lower VCEO (−45 V), higher hFE (250–630), SOT-23 package, 350 mW PD | Not suitable for >45 V circuits; limited power handling vs. 1.0 W rating of MPSW56RLRAG | Choose for space-constrained PCBs where voltage stress stays below 40 V and higher gain is prioritized |
Compared with MPSW56RLRAG, MPSW56RLRP offers identical performance in non-RoHS environments, while BC807-40LT1G trades voltage headroom and power capability for miniaturization and higher DC gain-making it appropriate only in lower-voltage, lower-power signal paths.

FAQ
What is the maximum collector-emitter voltage rating for MPSW56RLRAG?
The MPSW56RLRAG has a guaranteed VCEO rating of −80 Vdc, meaning it can safely block up to 80 volts in reverse bias between collector and emitter with IB = 0. This rating is validated per JEDEC test conditions (IC = −1.0 mAdc) and defines the upper limit for safe operation in high-side switch or amplifier configurations where collector voltage swings negative relative to emitter.
Is MPSW56RLRAG RoHS compliant and what does the 'G' suffix indicate?
Yes, MPSW56RLRAG is RoHS compliant. The 'G' suffix explicitly denotes a Pb-free package per onsemi's standard marking convention. This matches the ordering information stating "MPSW56RLRPG" and "MPSW55RLRAG" as Pb-free variants, and the device uses lead-free solderable terminations compatible with standard reflow profiles.
What is the DC current gain (hFE) specification for MPSW56RLRAG at typical operating conditions?
The MPSW56RLRAG guarantees hFE ≥ 50 when tested at IC = −250 mAdc and VCE = −1.0 Vdc at TA = 25°C. This minimum value is confirmed in the Electrical Characteristics table and applies across the full operating temperature range (−55°C to +150°C), ensuring consistent gain behavior in thermally demanding environments.
Can MPSW56RLRAG be used in switching applications, and what is its saturation voltage?
Yes, MPSW56RLRAG is qualified for switching use. Its VCE(sat) is specified as ≤ −0.5 Vdc when IC = −250 mAdc and IB = −10 mAdc. This low saturation voltage ensures minimal power loss and self-heating during on-state operation, making it suitable for driving relays, LEDs, and other medium-current loads in pulsed or DC mode.
What is the thermal resistance from junction to ambient (RJA) for MPSW56RLRAG in free-air conditions?
The thermal resistance from junction to ambient (RJA) for MPSW56RLRAG is 125°C/W under standard test conditions (TO-92 mounted on FR-4 board, no heatsink). This value determines how much the junction temperature rises above ambient per watt of dissipated power and must be applied with derating (8 mW/°C above 25°C) to maintain reliability within the −55°C to +150°C junction temperature range.
