Product details
Overview
PMBS3906,215 from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 (TO-236AB) package, rated for −40 V VCEO, −100 mA IC, and DC current gain (hFE) of 100–300 at −10 mA collector current. It serves as a compact, low-power switching or amplification device in space-constrained consumer and industrial signal-path circuits.
For engineers reviewing the PMBS3906,215 datasheet, PMBS3906,215 pinout, PMBS3906,215 application, or PMBS3906,215 equivalent, key selection criteria include verified PNP polarity, SOT23 footprint compatibility, guaranteed −40 V breakdown rating, −100 mA continuous current capability, and hFE consistency across production lots.
Technical Context
This discrete PNP BJT operates in active or saturation mode with base-emitter forward bias enabling controlled collector current flow. Its design supports linear amplification at low signal levels and robust on/off switching under pulsed or DC conditions up to 250 mW dissipation.
Thermal resistance of 500 K/W (junction-to-ambient, FR4 PCB) and junction temperature limit of 150 °C define its thermal envelope. Electrical behavior is characterized at 25 °C ambient, with hFE, VCE(sat), and fT = 150 MHz validated under specified test conditions including pulse width ≤ 300 µs and duty cycle ≤ 0.02.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −40 V - Maximum safe collector-emitter voltage with base open; defines off-state blocking capability in switching applications. |
| IC | −100 mA - Continuous DC collector current rating; sets upper bound for load-driving capacity in steady-state operation. |
| hFE | 100–300 - DC current gain at VCE = −1 V, IC = −10 mA; determines required base drive for target collector current. |
| VCE(sat) | −400 mV max at IC = −50 mA, IB = −5 mA - Saturation voltage defining conduction loss and heat generation during switch-on state. |
| fT | 150 MHz - Transition frequency at VCE = −20 V, IC = −10 mA; indicates usable bandwidth for small-signal amplification. |
| Ptot | 250 mW - Total power dissipation limit at Tamb ≤ 25 °C; constrains thermal design when operating near maximum ratings. |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount plastic package with 3 leads, 1.4 mm × 2.9 mm footprint, 1.1 mm height, and standard JEDEC-compliant soldering profiles (reflow and wave).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; forward-biased relative to emitter to enable PNP conduction; requires negative current injection for turn-on. |
| 2 | Emitter (E) | Current source terminal in PNP configuration; connected to higher potential rail; establishes reference for base-emitter voltage drop. |
| 3 | Collector (C) | Current sink terminal; carries load current to ground or lower-potential node; voltage swing limited by VCEO rating. |
Key Features
| Feature | Design Value |
|---|---|
| 100 mA continuous collector current | Supports medium-current digital logic interfacing and sensor signal buffering without external current boosting. |
| −40 V VCEO rating | Enables use in 24 V industrial control rails and automotive body electronics where transient overvoltage immunity is required. |
| hFE = 100–300 at −10 mA | Provides predictable base drive requirements across manufacturing lots, simplifying bias network design for amplifiers and switches. |
| fT = 150 MHz | Permits stable small-signal amplification up to mid-VHF range, suitable for RF front-end preamplifiers and oscillator buffers. |
Applications
| LED Driver Circuit | Level-Shifting Interface |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V microcontroller GPIO pins with inverted logic control. IC Role / Device Role / Timing Role: PNP switch configured in common-emitter topology, sinking current from LED anode to ground when base is pulled low. Use Value: Low VCE(sat) (≤ −400 mV) minimizes voltage drop across transistor, preserving LED forward voltage margin and reducing thermal load. |
Use Scenario: Translating 1.8 V logic outputs to interface with 5 V legacy peripherals requiring active-low enable signals. IC Role / Device Role / Timing Role: Voltage-level translator using saturated PNP switch to pull 5 V line low when input is high. Use Value: Verified hFE range ensures reliable saturation with minimal base current, eliminating need for additional buffer stages. |
| Low-Power Sensor Amplifier | Power-Rail Sequencing Control |
Use Scenario: Amplifying weak thermistor or photodiode signals in battery-powered environmental monitors. IC Role / Device Role / Timing Role: Small-signal common-emitter amplifier biased in active region for linear gain at sub-mA quiescent current. Use Value: fT = 150 MHz and low noise figure (4 dB) support clean amplification of signals up to ~10 kHz without added distortion. |
Use Scenario: Enabling 12 V auxiliary supply only after main 5 V rail stabilizes, using RC-delayed base drive. IC Role / Device Role / Timing Role: High-side switch controlling power-enable line to downstream ICs via emitter-follower configuration. Use Value: −40 V VCEO and −5 V VEBO ensure safe operation during rail sequencing transients and reverse-bias conditions. |
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 |
|---|---|---|---|
| MMBT3906LT1G | Same SOT23 package, but hFE min = 100 at −10 mA; VCEO = −40 V; VCE(sat) = −400 mV max at −50 mA, same test conditions. | Identical functional role; minor parametric spread in hFE distribution affects base resistor tolerance sensitivity. | Select when sourcing from ON Semiconductor distribution channels or requiring alternate qualification documentation. |
| BC807-16,215 | Higher hFE (160–230 min), same VCEO and IC; slightly higher VCE(sat) (−700 mV max at −100 mA). | Better suited for low-base-drive applications but less efficient in high-current saturation due to higher conduction loss. | Prefer for designs prioritizing gain stability over power efficiency at full rated current. |
Compared with MMBT3906LT1G and BC807-16,215, PMBS3906,215 offers tighter hFE consistency (100–300 vs. 100 min or 160–230), lower VCE(sat) at mid-currents, and optimized thermal resistance for FR4 PCB mounting-making it preferable for precision biasing and thermally constrained layouts.

FAQ
Is PMBS3906,215 suitable for automotive applications?
No. PMBS3906,215 is not automotive-qualified per Nexperia's official documentation. It lacks AEC-Q101 stress testing, extended temperature validation beyond −65 °C to +150 °C, and automotive-specific failure reporting. Use only in consumer, industrial, or commercial systems where automotive-grade reliability is not mandated.
What is the maximum peak collector current for PMBS3906,215?
The absolute maximum peak collector current is −200 mA, defined under pulsed conditions (pulse width ≤ 300 µs, duty cycle ≤ 0.02) per IEC 60134 limiting values. Continuous operation must remain within the −100 mA DC rating to avoid thermal runaway or parameter shift.
How does the SOT23 package affect thermal performance?
Mounted on FR4 PCB, PMBS3906,215 exhibits Rth(j-a) = 500 K/W, meaning a 250 mW dissipation raises junction temperature by 125 K above ambient. Layout practices-such as copper pour under the pad and thermal vias-must be applied to maintain Tj ≤ 150 °C in sustained operation.
Can PMBS3906,215 replace PMBS3904 in a circuit?
No-PMBS3904 is its NPN complement, with opposite polarity, different biasing requirements, and inverted current flow direction. Swapping them without circuit redesign causes functional failure. Use only as direct PNP replacement; for NPN functionality, select PMBS3904 or equivalent NPN transistors.
