Product details

Overview

PMBTA92-QVL from Nexperia is a PNP high-voltage bipolar junction transistor in SOT23 package, rated for −300 V V_CEO, −100 mA I_C, and qualified to AEC-Q101. It serves as a high-voltage switching or amplification element in off-state-isolated signal paths, such as telephone line interface circuits and telecom power control stages.

For engineers reviewing the PMBTA92-QVL datasheet, PMBTA92-QVL pinout, PMBTA92-QVL application, or PMBTA92-QVL equivalent, key selection criteria include verified −300 V breakdown rating, low-leakage (−250 nA I_CBO), AEC-Q101 qualification, SOT23 footprint compatibility, and PNP complement pairing with PMBTA42-Q.

Technical Context

This discrete PNP transistor operates in active or saturation mode with DC current gain (h_FE) of 40 at −10 V V_CE and −10 mA I_C, dropping to 25 at −30 mA I_C. Its −500 mV V_CE(sat) at −20 mA I_C/−2 mA I_B enables efficient low-power switching in high-impedance collector loads.

Thermal resistance R_th(j-a) is 500 K/W on standard FR4 PCB, limiting continuous power dissipation to 250 mW at T_amb ≤ 25 °C. Breakdown voltages are symmetrically rated: −300 V V_CBO and V_CEO, confirming robust high-voltage blocking capability under open-base or open-emitter conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−300 V: Maximum safe collector-emitter voltage with base open; supports isolation in 200–250 V telecom line interfaces.
I_C	−100 mA: Continuous collector current limit; suitable for low-current switching in relay drivers or protection circuits.
h_FE	40 (typ) at −10 mA: Predictable DC gain for biasing stability in linear amplifier or switch-mode feedback paths.
V_CE(sat)	−500 mV (max): Low saturation voltage ensures minimal power loss and heat generation in on-state switching.
I_CBO	−250 nA (max) at −200 V: Ultra-low leakage preserves high-impedance node integrity in standby or sensing applications.
f_T	50 MHz: Transition frequency supports moderate-speed switching up to ~10 MHz square-wave operation.
R_th(j-a)	500 K/W: Thermal resistance defines derating curve-requires board-level copper area or airflow above 50 mW.

Pinout & Package

SOT23 (TO-236AB) plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, 3-terminal configuration.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal for forward-biased PNP conduction; requires negative bias relative to emitter to turn on.
2	Emiter (E)	Current source terminal; connected to higher potential rail in high-side switch configurations.
3	Collector (C)	Current sink terminal; handles high-voltage load connection while maintaining isolation from base drive circuitry.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A110/A114.
−300 V breakdown rating	Enables direct interface with legacy telephony line voltages (−48 V nominal + ringing peaks up to −150 V).
SOT23 footprint	Standardized 3-pin SMD outline compatible with automated placement and reflow processes; reduces PCB real estate vs. TO-92.
Low I_CBO leakage	−250 nA max ensures stable off-state behavior in high-impedance monitoring or sample-hold circuits.

Applications

Telephone Line Interface

IC Role / Device Role / Timing Role: PNP emitter-follower buffer isolating control logic from sensitive analog ground planes.

Use Value: 40 h_FE provides stable bias current for op-amp input stages; SOT23 size allows dense layout near connectors.

Use Scenario: Amplifying microcontroller GPIO output to drive 5 V/12 V relay coils in programmable logic controllers.

IC Role / Device Role / Timing Role: Current-gain stage boosting weak MCU output to ≥20 mA coil drive capability.

Use Value: −100 mA I_C rating safely covers typical 15–18 mA relay hold currents; −300 V V_CBO suppresses back-EMF spikes.

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
BC807-40-Q	Lower V_CEO (−45 V), higher h_FE (250 min), same SOT23 package	Not suitable for >−50 V applications; optimized for general-purpose low-voltage switching	Select only when voltage stress remains below −40 V and higher gain is required.
MPSA92	Through-hole TO-92 package, −300 V V_CEO, −500 mA I_C, no AEC-Q101 qualification	Requires manual assembly; lacks automotive reliability validation; higher current capacity	Choose for prototyping or non-automotive industrial use where through-hole mounting is acceptable.

Compared with BC807-40-Q and MPSA92, PMBTA92-QVL uniquely combines AEC-Q101 qualification, SOT23 surface-mount compatibility, and full −300 V blocking-making it the only option for production automotive or telecom designs requiring all three attributes.

FAQ

What is the maximum allowable collector-emitter voltage for PMBTA92-QVL?

The absolute maximum V_CEO is −300 V with base open, per IEC 60134 limiting values. This rating applies under static DC conditions and must be derated linearly above 25 °C ambient temperature using the specified thermal resistance of 500 K/W.

Is PMBTA92-QVL suitable for automotive applications?

Yes-PMBTA92-QVL is fully qualified to AEC-Q101 standards, including stress tests for temperature cycling, high-temperature reverse bias, and electrostatic discharge. It is recommended for use in automotive body electronics, door modules, and lighting control systems operating from −40 °C to +125 °C.

How does the SOT23 package affect thermal performance?

In free air on standard FR4 PCB (single-sided, 35 µm Cu), R_th(j-a) is 500 K/W. At 25 °C ambient, this limits continuous power dissipation to 250 mW. For sustained >100 mW operation, additional copper pour or forced airflow is required to avoid exceeding 150 °C junction temperature.

What is the PNP complement to PMBTA92-QVL?

The NPN complement is PMBTA42-Q, which shares identical SOT23 packaging, −300 V V_CEO rating, AEC-Q101 qualification, and complementary pinout (1 = E, 2 = C, 3 = B). Both devices are designed for matched high-voltage switching pairs in push-pull or differential configurations.
