Product details
Overview
MPSA93RLRM from onsemi is a PNP silicon high-voltage general-purpose transistor in TO-92 package, rated for −200 VCEO, −200 VCBO, −5.0 VEBO, −500 mA continuous collector current, and 625 mW power dissipation at TA = 25°C. It serves as a high-voltage switching or amplification element in flyback snubber circuits, relay drivers, and industrial control interfaces.
For engineers reviewing the MPSA93RLRM datasheet, pinout, applications, or equivalent options, key selection criteria include verified VCEO = −200 V, hFE ≥ 25 at IC = −1.0 mA, VCE(sat) ≤ −0.4 V at IC/IB = 10, Ccb = 8.0 pF, and TO-92 mechanical compatibility with legacy through-hole layouts.
Technical Context
The MPSA93RLRM operates as a discrete PNP bipolar junction transistor optimized for high-voltage linear and switching applications up to 200 V reverse bias. Its DC current gain (hFE) is specified at multiple operating points: min 25 at IC = −1.0 mA, min 25 at IC = −30 mA, and typical fT = 50 MHz under VCE = −20 V, IC = −10 mA conditions.
Thermal performance is defined by RJA = 200°C/W (junction-to-ambient) and RJC = 83.3°C/W (junction-to-case), supporting operation across −55°C to +150°C junction temperature range. Safe operating area (SOA) curves confirm capability for pulsed loads up to 1 A at VCE = 10 V with 10 ms pulse width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −200 V - Maximum allowable collector-emitter voltage before breakdown; enables use in 170 VAC line-referenced circuits with safety margin. |
| IC (cont.) | −500 mA - Continuous collector current rating; supports relay coil drive up to ~400 mA with thermal derating above 25°C. |
| hFE (min) | 25 at IC = −30 mA - Minimum DC current gain ensures reliable saturation with base drive ≥3 mA in switching designs. |
| VCE(sat) | ≤ −0.4 V at IC = −20 mA, IB = −2 mA - Low saturation voltage minimizes power loss in high-side switch configurations. |
| Ccb | 8.0 pF at VCB = −20 V - Collector-base capacitance impacts high-frequency response and switching speed in snubber networks. |
| RJA | 200°C/W - Junction-to-ambient thermal resistance defines required PCB copper area and airflow for sustained 625 mW operation. |
Pinout & Package
Package: TO-92 (Case 29-11), straight-lead, Pb-free, epoxy-molded plastic package with standard lead spacing and mounting footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal of PNP transistor | Connected to higher potential node in high-side switch; polarity must be observed to avoid reverse-bias damage. |
| 2 (Collector) | Collector terminal of PNP transistor | Typically tied to load return path or ground-referenced circuit node; carries full switched current. |
| 3 (Base) | Control input for transistor conduction | Requires negative-going drive relative to emitter to turn on; base resistor sizing must ensure IB ≥ IC/hFE(min). |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | −200 V enables direct interface with 120/230 VAC-derived rails without external voltage clamping. |
| Pb-free TO-92 packaging | Complies with RoHS Directive 2011/65/EU; compatible with standard wave and reflow soldering profiles. |
| Wide temperature range | −55°C to +150°C operation supports deployment in industrial motor controls and outdoor power supplies. |
| Low VCE(sat) | ≤ −0.4 V reduces conduction losses in constant-current LED drivers and analog signal switching stages. |
Applications
| Industrial Relay Driver | AC Line Snubber Circuit |
|---|---|
Use Scenario: Driving 24 VDC or 120 VAC relay coils in programmable logic controllers and factory automation I/O modules. IC Role / Device Role / Timing Role: High-voltage PNP switch controlling coil energization/de-energization with galvanic isolation via optocoupler input stage. Use Value: −200 VCEO withstands back-EMF spikes exceeding 150 V, eliminating need for external flyback diodes in many designs. |
Use Scenario: Absorbing voltage transients across triac/SCR outputs in solid-state AC switches and dimmer modules. IC Role / Device Role / Timing Role: Fast-switching PNP clamp that conducts during overvoltage events to limit dv/dt and protect sensitive gate drivers. Use Value: 8.0 pF Ccb and 50 MHz fT support sub-microsecond response to transient edges without oscillation. |
| High-Side Load Switch | Analog Signal Level Shifter |
Use Scenario: Enabling/disabling 5–24 V sensor power rails in automotive body control modules and industrial sensors. IC Role / Device Role / Timing Role: PNP-based high-side switch controlled by microcontroller GPIO with inverted logic interface. Use Value: VCE(sat) ≤ −0.4 V ensures <100 mW dissipation at 200 mA load, enabling compact thermal design without heatsinking. |
Use Scenario: Translating 3.3 V logic signals to −5 V or −12 V domains in mixed-supply test equipment and instrumentation front-ends. IC Role / Device Role / Timing Role: Inverting level shifter using emitter-follower or common-emitter configuration with fixed bias network. Use Value: hFE ≥ 25 at low IC ensures stable DC transfer characteristics across temperature, minimizing offset drift. |
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 |
|---|---|---|---|
| MPSA93G | Same die, TO-92 bulk pack (5000 units/box); no ammo-pack marking or reel orientation coding. | Preferred for manual prototyping and low-volume production where tape-and-reel handling is unnecessary. | Select MPSA93G when automated assembly is not required and cost-per-unit is prioritized over packaging convenience. |
| BC639 | Lower VCEO = −60 V, higher hFE = 40–250, same TO-92 package; not rated for >100 V applications. | Suitable only for low-voltage DC switching (e.g., 24 V motor drivers), not AC line-referenced designs. | Choose BC639 only if system maximum VCE remains below 50 V and higher gain variability is acceptable. |
Compared with MPSA93RLRM, MPSA93G offers identical electrical performance in a lower-cost bulk format but lacks ammo-pack traceability and reel compatibility; BC639 provides higher gain but fails to meet the −200 V breakdown requirement, limiting use to sub-60 V systems.

FAQ
What is the maximum safe collector-emitter voltage for MPSA93RLRM?
The MPSA93RLRM has a guaranteed minimum V(BR)CEO of −200 Vdc at IC = −1.0 mA, meaning it can safely block up to −200 V between collector and emitter under specified test conditions. Designers should apply appropriate derating-typically 20%-for long-term reliability in repetitive switching applications. The MPSA93RLRM datasheet confirms this rating is validated per JEDEC JESD22-A114.
Does MPSA93RLRM support surface-mount assembly?
No, the MPSA93RLRM is supplied exclusively in the through-hole TO-92 (Case 29-11) package with straight leads and is not qualified for SMT reflow or wave soldering without mechanical adaptation. Its pinout and thermal profile are optimized for axial-lead insertion and hand-soldering or selective wave processes. For SMT equivalents, consider onsemi's NSS series or other SOT-23 PNP alternatives-not the MPSA93RLRM.
What is the typical DC current gain (hFE) of MPSA93RLRM at 10 mA collector current?
The MPSA93RLRM exhibits a minimum hFE of 25 at IC = −10 mA and VCE = −10 V, with typical values ranging from 50 to 100 depending on unit variation and temperature. This gain is confirmed in Figure 1 of the official onsemi MPSA92/D datasheet, which applies identically to MPSA93RLRM as part of the same die family. Always verify hFE in-circuit under actual operating conditions.
Can MPSA93RLRM replace MPSA92 in existing designs?
No-MPSA93RLRM is not a drop-in replacement for MPSA92 due to its lower VCEO (−200 V vs. −300 V) and reduced VCBO. While both share identical pinout and package, substituting MPSA93RLRM into a design originally specifying MPSA92 may result in premature breakdown under high-voltage transients. The MPSA93RLRM must be evaluated independently for voltage margin compliance before any substitution.
Is MPSA93RLRM compliant with RoHS and REACH regulations?
Yes, the MPSA93RLRM is marked "G" in its ordering code and explicitly designated as Pb-free in onsemi's official documentation, meeting EU RoHS Directive 2011/65/EU and REACH SVHC requirements. Its TO-92 package uses lead-free molding compound and termination plating, and full compliance documentation is available via onsemi's product change notices and material declarations portal.
