Product details
Overview
BSR30F from Nexperia is a PNP medium-power bipolar junction transistor in SOT89 package, rated for −60 V VCEO, −1 A continuous collector current, and 1.35 W power dissipation at Tamb ≤ 25 °C. It serves as a high-side switch or linear regulator pass element in battery-powered systems and MOSFET driver stages.
For engineers reviewing the BSR30F datasheet, BSR30F pinout, BSR30F application, or BSR30F equivalent, key selection criteria include verified −60 V breakdown rating, −1 A DC current capability, exposed heatsink thermal performance (Rth(j-sp) = 13 K/W), hFE range of 40–120 at −100 mA, and SOT89 mechanical compatibility with FR4 PCBs.
Technical Context
This PNP transistor operates in active, saturation, and cutoff regions with defined DC gain (hFE) across −100 µA to −500 mA collector currents and exhibits low VCE(sat) (−0.25 V typical at −150 mA/−15 mA) for efficient switching in high-side configurations.
Its thermal design relies on the exposed collector pad in the SOT89 package, delivering Rth(j-a) = 93 K/W in free air and Rth(j-sp) = 13 K/W to solder point-enabling stable operation up to 150 °C junction temperature under pulsed or linear conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V: Maximum safe collector-emitter voltage with base open; defines high-side switch voltage headroom in 48 V or 36 V battery systems. |
| IC | −1 A continuous: Sustained load current capability; supports regulators or drivers for loads up to ~12 W at 12 V input. |
| Ptot | 1.35 W at Tamb ≤ 25 °C: Power handling with standard FR4 mounting; requires thermal pad area ≥6 cm² for full rating. |
| hFE | 40–120 at VCE = −5 V, IC = −100 mA: Predictable DC gain for bias network design in linear amplifiers or emitter-follower regulators. |
| VCE(sat) | −0.25 V typical at IC = −150 mA, IB = −15 mA: Low saturation voltage minimizes conduction loss in switching applications. |
| fT | 100 MHz at VCE = −10 V, IC = −50 mA: Supports moderate-speed switching (e.g., <500 kHz PWM) and RF pre-driver use. |
Pinout & Package
The BSR30F is housed in a SOT89 plastic surface-mount package with an exposed collector pad for thermal and electrical conduction. Dimensions: 4.5 mm × 2.5 mm × 1.5 mm body, 1.5 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (E) | Current exit path; connected to load ground or reference node in high-side switch topology. |
| 2 | Collector (C) | Main current sink terminal and thermal interface; soldered to large copper pad for heat dissipation and low-impedance return path. |
| 3 | Base (B) | Control input; requires current-limited drive (e.g., resistor from microcontroller GPIO) to achieve target IC. |
Key Features
| Feature | Design Value |
|---|---|
| Exposed collector pad | Enables direct thermal coupling to PCB copper; achieves Rth(j-sp) = 13 K/W for stable operation under sustained load. |
| High VCEO rating | −60 V supports use in 48 V automotive auxiliary circuits or industrial 36 V DC systems without derating. |
| Peak current capability | ICM = −2 A (1 ms pulse) allows brief surge handling in motor start-up or inrush limiting applications. |
| Low VBE(sat) | −1.2 V max at IC = −500 mA/IB = −50 mA eases drive requirements from logic-level sources. |
Applications
| Linear Voltage Regulators | High-Side Switches |
|---|---|
Use Scenario: Adjustable positive-output LDO using PNP pass transistor with feedback control loop. IC Role / Device Role / Timing Role: Pass element regulating output voltage by modulating emitter-collector current based on error amplifier signal. Use Value: Delivers low-noise, ripple-free output with VCE(sat) ≤ −0.5 V enabling <1 V dropout at 1 A load. |
Use Scenario: Power enable control for subsystems in portable medical devices or IoT sensors. IC Role / Device Role / Timing Role: High-side load switch isolating downstream circuitry from main battery rail. Use Value: −60 V VCEO provides margin against load-dump transients; exposed pad ensures thermal stability during 100% duty-cycle operation. |
| Battery-Driven Devices | MOSFET Drivers |
Use Scenario: Reverse-polarity protection and load switching in handheld test equipment powered by Li-ion packs. IC Role / Device Role / Timing Role: PNP configured as ideal diode or controlled series switch between battery and system input. Use Value: hFE ≥ 40 ensures reliable turn-on with microcontroller GPIO drive; low ICBO (<100 nA) preserves battery life in standby. |
Use Scenario: Level-shifting gate drive stage for N-channel high-side MOSFETs in half-bridge motor controllers. IC Role / Device Role / Timing Role: Active pull-down and fast turn-off enabler for MOSFET gate via complementary PNP-NPN pair. Use Value: fT = 100 MHz supports clean 100 ns–1 µs edge transitions; VCE(sat) < −0.5 V minimizes driver losses. |
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 |
|---|---|---|---|
| BC807-40W | SOT323 package, lower Ptot (300 mW), VCEO = −45 V, hFE = 250–630 | Not suitable for >45 V rails or >300 mW continuous dissipation; better for low-current signal switching. | Select when board space is critical and power demands are ≤300 mW with no need for exposed thermal pad. |
| ZTX753 | TO-92 package, Ptot = 1 W, VCEO = −60 V, hFE = 100–300, no exposed pad | Higher thermal resistance (Rth(j-a) ≈ 150 K/W); requires heatsink for >500 mA continuous use. | Choose for through-hole prototyping or legacy designs where SMT thermal management is impractical. |
Compared with BC807-40W and ZTX753, the BSR30F uniquely combines SOT89's exposed-pad thermal performance, −60 V rating, and 1.35 W dissipation-making it optimal for compact, high-reliability linear or switching roles where thermal headroom and voltage margin are critical.

FAQ
What is the maximum allowable junction temperature for BSR30F?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. Operation above this threshold risks permanent degradation. Derating is required above 25 °C ambient-e.g., at 70 °C ambient, maximum usable power drops to ~0.8 W with standard FR4 mounting and 6 cm² copper pad.
Can BSR30F be used in automotive applications?
No-BSR30F is explicitly marked as non-automotive qualified in the revision history. It lacks AEC-Q101 qualification and has not undergone automotive stress testing. For automotive use, Nexperia offers the BSR30-Q variant, which meets AEC-Q101 requirements and supports extended temperature and reliability validation.
How does the exposed collector pad affect PCB layout?
The exposed collector pad (Pin 2) must be connected to a minimum 6 cm² copper area on the top layer of an FR4 PCB, tin-plated and single-sided, to achieve the rated 1.35 W power dissipation. Thermal vias to inner or bottom-layer planes are recommended but not counted toward the 6 cm² requirement unless specified in validated layout guidelines.
Is base resistor calculation required for reliable switching?
Yes-BSR30F is a current-controlled device. To ensure saturation at IC = −1 A, base current must exceed IC/hFE(min) = −1 A/40 = −25 mA. With VBE(sat) ≈ −1.2 V, a 220 Ω resistor from a 3.3 V GPIO yields ~10 mA-insufficient. A 100 Ω resistor (or active driver) is needed for full-load saturation.
