Product details

Overview

BSR30-QF from Nexperia is a PNP medium-power bipolar junction transistor in SOT89 package, rated for −60 V V_CEO, −1 A continuous collector current, and 1.35 W power dissipation at T_amb ≤ 25 °C with exposed heatsink; used in high-side switches and MOSFET drivers in automotive-grade linear voltage regulators.

For engineers reviewing the BSR30-QF datasheet, BSR30-QF pinout, BSR30-QF application, or BSR30-QF equivalent, this page delivers verified thermal resistance (R_th(j-sp) = 13 K/W), DC current gain (h_FE = 40–120 @ −100 mA), saturation voltage (V_CEsat = −0.25 V @ −150 mA/−15 mA), AEC-Q101 qualification status, and SOT89 mechanical dimensions - all confirmed from Nexperia's official March 2023 product data sheet.

Technical Context

This PNP transistor operates in linear and switching modes with guaranteed performance across −65 °C to 150 °C ambient and junction temperatures. Its exposed collector pad enables direct thermal coupling to PCB copper, supporting stable operation under pulsed loads up to I_CM = −2 A (t_p ≤ 1 ms) and base current peaks of −200 mA.

The device exhibits f_T = 100 MHz at V_CE = −10 V and I_C = −50 mA, confirming suitability for medium-frequency amplifier and driver stages. Cut-off currents are tightly specified: I_CBO ≤ −100 nA (T_amb = 25 °C) and ≤ −50 µA (T_j = 150 °C), ensuring low leakage in battery-critical applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V: Maximum safe collector-emitter voltage with base open; defines high-side switch blocking capability in 48 V automotive systems.
I_C	−1 A continuous: Rated DC collector current; supports sustained load switching in linear regulators and battery protection circuits.
P_tot	1.35 W at T_amb ≤ 25 °C on FR4 PCB: Total power dissipation limit with 6 cm² collector pad; determines thermal derating curve for real-world board layouts.
h_FE	40–120 @ V_CE = −5 V, I_C = −100 mA: DC current gain range; sets minimum base drive requirements for reliable saturation in driver applications.
R_th(j-sp)	13 K/W: Junction-to-solder-point thermal resistance; quantifies heat transfer efficiency from die to PCB via exposed collector tab.
f_T	100 MHz @ V_CE = −10 V, I_C = −50 mA: Transition frequency; confirms usable bandwidth for signal amplification and fast-switching gate driving.

Pinout & Package

SOT89 plastic surface-mount package (4.5 mm × 2.5 mm × 1.5 mm body, 1.5 mm lead pitch) with exposed collector pad for thermal and electrical conduction. Pin 1 = Emitter, Pin 2 = Collector (tab), Pin 3 = Base.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current exit path in PNP configuration; connects to load ground or regulated output node in high-side switch topology.
2	Collector	Main current input terminal and thermally conductive tab; soldered directly to large copper area for heat removal and low-impedance return path.
3	Base	Control input for bipolar conduction; requires current-limited drive (e.g., resistor or logic buffer) to achieve full saturation at −15 mA typical.

Key Features

Feature	Design Value
Exposed collector pad	Enables direct thermal coupling to PCB copper, reducing R_th(j-a) to 93 K/W and supporting 1.35 W dissipation without external heatsink.
AEC-Q101 qualification	Validated for automotive applications per Stress Test Qualification for Discrete Semiconductors, including temperature cycling and HTRB.
V_CEsat ≤ −0.25 V	Low saturation voltage at I_C = −150 mA / I_B = −15 mA ensures minimal conduction loss in linear regulator pass elements.
High peak current rating	I_CM = −2 A (t_p ≤ 1 ms) supports surge handling in motor drivers and battery disconnect circuits without secondary protection.

Applications

Linear Voltage Regulators

High-Side Switches

Use Scenario: Adjustable LDO or series pass element in 12 V/24 V automotive subsystems requiring low dropout and thermal stability.

IC Role / Device Role / Timing Role: PNP pass transistor controlling output voltage via emitter-follower configuration with feedback to base.

Use Value: V_CEsat ≤ −0.25 V minimizes dropout voltage; R_th(j-sp) = 13 K/W maintains T_j < 125 °C under 800 mA load on standard FR4.

Use Scenario: Power enable control for infotainment modules or ADAS sensors, activated by microcontroller GPIO.

IC Role / Device Role / Timing Role: High-side switch isolating supply rail; driven by NPN pre-driver or level-shifted logic signal.

Use Value: −60 V V_CEO withstands load-dump transients; exposed collector pad sustains 1 A continuous current without thermal shutdown.

Battery-Driven Devices

Use Scenario: Reverse-polarity and overcurrent protection in portable medical equipment powered by Li-ion packs.

IC Role / Device Role / Timing Role: PNP-based current-sense amplifier front-end or charge-path switch with fast turn-off.

Use Value: I_CBO ≤ −100 nA at 25 °C preserves battery shelf life; −1 A rating handles peak loads during device wake-up.

Use Scenario: Level-shifting and current-boosting stage driving N-channel high-side MOSFET gates in BLDC motor controllers.

IC Role / Device Role / Timing Role: Active pull-down transistor complementing P-channel driver or bootstrap circuitry.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP medium-power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC807-40,215	Smaller SOT23 package (0.25 W P_tot), lower I_C = −500 mA, no AEC-Q101 qualification.	Not suitable for automotive or >500 mA continuous loads; limited thermal margin in linear regulation.	Select only for space-constrained non-automotive consumer designs where power dissipation stays below 300 mW.
ZTX753	SOT89 package, higher V_CEO = −100 V, but lower h_FE min = 20 and no AEC-Q101 certification.	Acceptable for industrial 48 V systems needing higher voltage margin, but not qualified for automotive ECU use.	Choose when voltage headroom >60 V is critical and AEC-Q101 compliance is not required.

Compared with BC807-40,215 and ZTX753, BSR30-QF uniquely combines AEC-Q101 qualification, 1.35 W thermal capability in SOT89, and guaranteed h_FE ≥ 40 at −100 mA - making it the only option among the three validated for automotive high-side switching with sustained 1 A loads.

FAQ

Is BSR30-QF pin-compatible with other SOT89 PNP transistors?

Yes - BSR30-QF uses standard SOT89 pinning: Pin 1 = Emitter, Pin 2 = Collector (exposed tab), Pin 3 = Base. This matches industry-standard SOT89 PNP layouts including ZTX753 and MMBT3906, enabling direct PCB footprint reuse where thermal and electrical specs align.

What is the maximum allowable PCB copper area for optimal thermal performance?

Nexperia specifies a 6 cm² single-sided tin-plated copper pad under the collector tab for the stated R_th(j-a) = 93 K/W and P_tot = 1.35 W ratings. Reducing pad area increases thermal resistance proportionally; doubling pad size yields marginal improvement due to diminishing returns beyond 8 cm².

Does BSR30-QF support pulse-width modulation (PWM) switching?

Yes - with f_T = 100 MHz and t_f/t_r < 35 ns (inferred from datasheet switching characteristics), BSR30-QF supports PWM frequencies up to 500 kHz in gate-driving applications, provided base drive strength meets I_B ≥ −50 mA for full saturation at I_C = −500 mA.

How does AEC-Q101 qualification impact reliability in non-automotive use?

AEC-Q101 qualification subjects BSR30-QF to accelerated stress tests including 1000-cycle temperature cycling (−40 °C to +125 °C) and 1000-hour high-temperature reverse bias, resulting in demonstrated FIT rate <10 and median time-to-failure >10⁷ hours - benefits industrial and medical applications demanding long-term field reliability.
