Product details
Overview
MPSW56RLRP from onsemi is a PNP silicon small-signal transistor rated for −80 VCEO, −500 mA continuous collector current, and 1.0 W dissipation at TA = 25°C, used in low-power amplifier and switching applications such as audio preamplifier stages and relay drivers.
For engineers reviewing the MPSW56RLRP datasheet, pinout, applications, or equivalent options, key selection criteria include its −80 VCEO rating, hFE ≥ 50 at −250 mA, VCE(sat) ≤ −0.5 V, and TO−92 package compatibility with through-hole prototyping and industrial control PCBs.
Technical Context
This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with verified DC current gain (hFE) of 50 minimum at IC = −250 mA and VCE = −1.0 V, and exhibits fT = 50 MHz under specified small-signal conditions.
Its thermal resistance RJA is 125°C/W and RJC is 50°C/W, supporting operation from −55°C to +150°C junction temperature, with safe operating area limited by second breakdown and thermal constraints per Figure 7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum allowable collector-emitter voltage before breakdown in common-emitter configuration |
| IC (continuous) | −500 mA - Continuous collector current handling capability without derating at 25°C ambient |
| PD @ TA = 25°C | 1.0 W - Maximum power dissipation in free-air, derated by 8 mW/°C above 25°C |
| hFE | ≥ 50 - Minimum DC current gain at −250 mA collector current and −1.0 V collector-emitter voltage |
| VCE(sat) | ≤ −0.5 V - Collector-emitter saturation voltage at −250 mA IC and −10 mA IB, defining low-loss switching state |
| fT | 50 MHz - Current-gain bandwidth product indicating usable frequency range for small-signal amplification |
Pinout & Package
Package: TO−92 (Case 29−10), 3-lead through-hole plastic package with bent leads, 1 W power rating, Pb-free compliant (as indicated by "G" suffix in marking variants).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Current exit terminal in PNP configuration; connected to most positive supply rail in common-emitter amplifier layouts |
| 2 | Base | Control electrode; negative bias relative to emitter required to forward-bias base-emitter junction and enable conduction |
| 3 | Collector | Current entry terminal; typically tied to load and negative supply in switching or amplifier output stage |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | −80 V enables use in higher-voltage industrial control circuits where MPSW55 (−60 V) would be insufficient |
| Guaranteed hFE at high IC | Minimum 50 at −250 mA ensures predictable gain in medium-current linear amplification stages |
| Low VCE(sat) | ≤ −0.5 V reduces conduction losses in saturated-switching applications like LED or relay drivers |
| TO−92 mechanical standardization | Compatible with legacy through-hole assembly processes and hand-soldered evaluation boards |
Applications
| Audio Preamp Stage | Relay Driver Circuit |
|---|---|
Use Scenario: Low-noise voltage amplification of microphone or line-level signals prior to ADC sampling in embedded audio systems. IC Role / Device Role / Timing Role: PNP small-signal amplifier configured in common-emitter topology with emitter degeneration for stable gain. Use Value: −80 VCEO headroom supports ±15 V supply rails; hFE ≥ 50 ensures sufficient drive for next-stage input impedance without added buffering. | Use Scenario: Driving electromagnetic relays in programmable logic controllers (PLCs) and HVAC control panels. IC Role / Device Role / Timing Role: Saturated switch controlling relay coil current, turned on/off by microcontroller GPIO. Use Value: VCE(sat) ≤ −0.5 V minimizes power loss and self-heating during sustained coil energization; TO−92 mounting allows direct PCB integration near relay footprint. |
| DC Motor Speed Control | Power Supply Foldback Protection |
Use Scenario: Pulse-width modulated (PWM) switching of small brushed DC motors in battery-powered tools and actuators. IC Role / Device Role / Timing Role: Low-side PNP switch (with level-shifting) or high-side driver in discrete H-bridge half-bridge sections. Use Value: fT = 50 MHz supports clean PWM edge fidelity up to ~500 kHz; −500 mA IC rating covers typical motor stall currents below 400 mA. | Use Scenario: Current-limiting element in linear regulator foldback circuits to protect against short-circuit overloads. IC Role / Device Role / Timing Role: Sensing and shunting excess current via emitter-follower configuration with external sense resistor. Use Value: Tight VBE(on) specification (≤ −1.2 V) enables precise current threshold setting; −4.0 VEBO rating ensures reliable base-emitter reverse blocking during fault recovery. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPSW56RLRPG | Identical electrical specs; Pb-free variant with same TO−92 package and 2000-unit ammo pack shipping | No functional difference; selected when RoHS compliance is mandatory and lead-free soldering is used | Direct replacement where Pb-free certification is required; no layout or schematic change needed |
| BC558 | Lower VCEO (−30 V), lower IC (−100 mA), hFE min 110 at −2 mA - not rated for −250 mA or −80 V operation | Suitable only for low-voltage, low-current signal switching; cannot replace MPSW56RLRP in 24 V relay or 48 V motor control | Select BC558 only for sub-10 mA bias networks or low-voltage logic interfacing; verify VCEO and IC margins first |
Compared with MPSW56RLRP, MPSW56RLRPG offers identical performance with RoHS compliance, while BC558 provides higher hFE at micro-currents but fails critical voltage and current ratings - making it unsuitable for direct substitution in high-stress amplifier or switching roles.

FAQ
What is the maximum collector-emitter voltage rating for MPSW56RLRP?
The MPSW56RLRP has a guaranteed minimum VCEO rating of −80 Vdc, meaning it can safely block up to 80 V between collector and emitter with base open. This exceeds the −60 V rating of the MPSW55 and makes MPSW56RLRP suitable for 24 V and 48 V industrial control rails where higher voltage margin is required.
Does MPSW56RLRP support high-frequency amplification?
Yes, the MPSW56RLRP has a current-gain bandwidth product (fT) of 50 MHz under test conditions of IC = −250 mAdc, VCE = −5.0 Vdc, and f = 20 MHz. This confirms usable small-signal gain up to several megahertz, appropriate for audio preamplifiers and medium-speed switching, though not RF or GHz-range applications.
Is MPSW56RLRP RoHS-compliant?
Yes, the MPSW56RLRP is RoHS-compliant. Its Pb-free status is confirmed in the official datasheet (Rev. 4, August 2010), and the "G" suffix in variants like MPSW56RLRPG explicitly denotes Pb-free packaging. The device meets JEDEC J-STD-609A Class 1 marking requirements.
What is the thermal resistance of MPSW56RLRP in free air?
The MPSW56RLRP has a thermal resistance from junction-to-ambient (RJA) of 125°C/W when mounted on a standard FR-4 PCB with minimal copper area. This value assumes natural convection cooling and defines the temperature rise per watt dissipated - critical for calculating safe operating limits in enclosed or high-ambient environments.
Can MPSW56RLRP replace MPSW55 in existing designs?
MPSW56RLRP can replace MPSW55 in most designs due to identical pinout, package, and gain characteristics, but only if the higher −80 VCEO rating is beneficial or non-detrimental. It is not a drop-in substitute where circuit stress analysis relies on the lower MPSW55 breakdown margin - always verify voltage transients and clamp behavior before substitution.
