Product details
Overview
PMBTA56,215 from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 package, rated for −80 V VCEO, −500 mA IC, and 100 minimum hFE at −10 mA collector current; used for low-voltage switching and amplification in telephony interface stages and professional communication equipment power control circuits.
For engineers reviewing the PMBTA56,215 datasheet, PMBTA56,215 pinout, PMBTA56,215 application, or PMBTA56,215 equivalent, this page delivers verified electrical parameters, SOT23 terminal mapping, thermal resistance (500 K/W), saturation voltage (−0.25 V at −100 mA/−10 mA), and direct alternatives with documented functional alignment.
Technical Context
The PMBTA56,215 operates as a silicon PNP BJT with open-base VCEO = −80 V and peak IC = −1 A, supporting linear amplification and saturated switching in DC-coupled signal paths. Its hFE remains ≥100 from −10 mA to −100 mA at 25 °C, enabling predictable base drive design.
Thermal performance is defined for FR4 PCB mounting (single-sided, 35 μm Cu): Rth(j-a) = 500 K/W, with Tj max = 150 °C and ambient operating range −65 °C to +150 °C. VBE(sat) reaches −1.2 V at −100 mA, confirming robust forward-bias conduction under load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum safe collector-emitter voltage with base open; defines breakdown margin in high-side switch configurations. |
| IC | −500 mA continuous - Sustained collector current rating; supports relay drivers and LED array switches up to 0.5 A. |
| hFE | ≥100 at −10 mA - Minimum DC current gain ensures reliable base current sizing for low-power logic-level interfacing. |
| VCE(sat) | ≤−0.25 V at −100 mA/−10 mA - Low saturation voltage minimizes power loss and heat generation in switching applications. |
| Rth(j-a) | 500 K/W - Junction-to-ambient thermal resistance on standard FR4; sets maximum power dissipation limit at 250 mW. |
| fT | 50 MHz - Transition frequency confirms usable bandwidth for audio-frequency amplification and fast digital switching. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch); thermally optimized for reflow soldering on FR4 PCBs with standard footprint per Fig. 7.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control electrode; requires negative bias relative to emitter to turn on PNP device; typical drive current ≤200 mA peak. |
| 2 | Emitter (E) | Current source terminal; connected to higher potential rail in high-side switch topologies; carries full load current. |
| 3 | Collector (C) | Current sink terminal; tied to load and ground reference; voltage swing limited to −80 V maximum relative to emitter. |
Key Features
| Feature | Design Value |
|---|---|
| High current capability | Rated −500 mA continuous collector current enables direct driving of small relays and indicator LEDs without external buffering. |
| Low saturation voltage | VCE(sat) ≤ −0.25 V at IC/IB = 10 ensures <125 mW conduction loss at 500 mA, reducing thermal stress in compact layouts. |
| Wide temperature operation | Specified from −65 °C to +150 °C ambient allows deployment in industrial enclosures and unregulated outdoor telecom cabinets. |
| Complementary NPN pairing | Direct counterpart PMBTA06 enables matched push-pull amplifier stages and dual-rail switching circuits with consistent gain and timing. |
Applications
| Telephony Line Interface | Professional Audio Signal Switching |
|---|---|
Use Scenario: Controlling analog signal routing between hybrid circuits and codec ICs in VoIP gateways. IC Role / Device Role / Timing Role: PNP switch enabling bidirectional AC-coupled path selection with minimal insertion loss. Use Value: VCEO = −80 V withstands line transients; hFE ≥100 ensures stable bias across temperature for consistent on-resistance. |
Use Scenario: Muting/unmuting microphone preamp outputs during channel switching in broadcast mixers. IC Role / Device Role / Timing Role: Fast-turnoff PNP shunt switch grounding signal path when inactive. Use Value: fT = 50 MHz supports clean muting up to 20 kHz; VCE(sat) ≤ −0.25 V prevents audible pop artifacts. |
| Industrial Sensor Signal Conditioning | Low-Voltage Power Sequencing |
Use Scenario: Amplifying millivolt-level thermocouple outputs before ADC input in PLC analog input modules. IC Role / Device Role / Timing Role: DC-coupled common-emitter amplifier stage with fixed-gain bias network. Use Value: hFE stability over −40 °C to +125 °C maintains calibration accuracy; low VBE drift reduces offset error. |
Use Scenario: Enabling 3.3 V and 5 V rails in sequence using microcontroller GPIO-controlled high-side switches. IC Role / Device Role / Timing Role: High-side PNP pass element controlled by inverted logic signal. Use Value: −80 V VCBO provides headroom above 5 V rail; Rth(j-a) = 500 K/W permits 250 mW dissipation in space-constrained board areas. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC807-40,215 | Same SOT23 package; hFE = 250–630 (min 40) vs. PMBTA56's min 100; VCEO = −45 V vs. −80 V. | Lower voltage rating restricts use in >45 V systems; higher hFE reduces required base drive but increases sensitivity to leakage. | Select when higher gain and lower base current are prioritized over voltage margin in 24 V industrial controls. |
| MMBT5401LT1G | TO-236 (SOT-23) package; VCEO = −60 V; IC = −600 mA; hFE = 60–250 at −10 mA. | Higher current rating suits 600 mA loads; reduced voltage headroom limits use in −48 V telecom systems. | Choose for higher current capacity where −60 V breakdown suffices and tighter hFE tolerance is acceptable. |
Compared with BC807-40,215 and MMBT5401LT1G, PMBTA56,215 offers the highest VCEO (−80 V) among SOT23 PNP transistors, making it uniquely suitable for legacy −48 V telecom and high-transient industrial interfaces where voltage margin is critical.

FAQ
Is PMBTA56,215 suitable for automotive applications?
No. The PMBTA56,215 is explicitly designated as non-automotive qualified in its revision history (v.3, April 2023). It lacks AEC-Q101 qualification, has no automotive-grade screening, and is not tested to automotive temperature or reliability standards. Use only in industrial, telecom, or consumer equipment.
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is −200 mA (single pulse, tp ≤ 1 ms), but continuous base current must be sized to keep IC ≤ −500 mA and Ptot ≤ 250 mW. At hFE = 100 and IC = −500 mA, IB ≈ −5 mA; sustained IB > −10 mA risks exceeding thermal limits on standard FR4.
How does PMBTA56,215 compare to its NPN complement PMBTA06?
PMBTA06 shares identical SOT23 package, thermal characteristics, and voltage/current ratings (VCEO = 80 V, IC = 500 mA), but with opposite polarity. Both exhibit matched hFE ranges and saturation behavior, enabling symmetrical push-pull designs and complementary bias networks in amplifier and switching circuits.
Can PMBTA56,215 be used in linear amplifier mode with stable gain?
Yes. With hFE ≥100 from −10 mA to −100 mA and minimal variation across −40 °C to +125 °C (Fig. 1), the PMBTA56,215 supports stable common-emitter amplification. Designers must maintain VCE > 1 V and limit power dissipation to ≤250 mW using appropriate emitter degeneration and thermal layout.
