Product details
Overview
BSR30,115 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 BSR30,115 datasheet, BSR30,115 pinout, BSR30,115 application, or BSR30,115 equivalent, key selection criteria include its exposed heatsink thermal path (Rth(j-sp) = 13 K/W), DC current gain range (hFE = 40–120 at −100 mA), and −0.25 V VCEsat at −150 mA/−15 mA drive.
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 design emphasizes thermal management via an exposed collector pad and supports pulsed operation up to 2 A ICM with 1 ms pulse width.
The device exhibits low saturation voltage (−0.25 V typical at −150 mA) and transition frequency of 100 MHz at −10 V VCE, −50 mA IC, enabling use in medium-speed switching and analog amplification where gain stability and thermal robustness are critical.
Key Specifications

| Ptot | 1.35 W - Total power dissipation on FR4 PCB with 6 cm² collector pad; determines thermal derating envelope |
| hFE | 40–120 - DC current gain at −5 V VCE, −100 mA IC; enables predictable base drive sizing |
| VCEsat | −0.25 V (typ.) - Collector-emitter saturation voltage at −150 mA IC/−15 mA IB; minimizes conduction loss in switching |
| Rth(j-sp) | 13 K/W - Junction-to-solder-point thermal resistance; enables direct thermal coupling to PCB copper |
| fT | 100 MHz - Transition frequency at −10 V VCE, −50 mA IC; supports medium-frequency signal amplification |

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 |
|---|---|---|---|
| BC807-40,115 | Lower IC (−500 mA), smaller SOT23 package, no exposed pad | Limited to sub-500 mA loads; unsuitable for >1 W thermal dissipation | Select when board space is constrained and thermal load is light |
| ZTX753 | Higher VCEO (−100 V), TO-92 package, Rth(j-a) = 200 K/W | Requires heatsink for >300 mW; not surface-mount optimized | Select when higher voltage blocking is required and through-hole assembly is acceptable |
Compared with BC807-40,115 and ZTX753, BSR30,115 uniquely balances 1 A current handling, SOT89 surface-mount compatibility, and low-thermal-resistance exposed collector-making it optimal for compact, thermally demanding high-side switches and regulators.

FAQ
What is the maximum allowable junction temperature for BSR30,115?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation above this temperature risks permanent degradation. Derating is required above 25 °C ambient per the thermal resistance data: Rth(j-a) = 93 K/W in free air, so usable power drops linearly with rising ambient temperature.
Can BSR30,115 be used in automotive applications?
No-BSR30,115 is explicitly marked as non-automotive qualified in the revision history. It lacks AEC-Q101 qualification and has not undergone automotive-grade stress testing. For automotive use, Nexperia offers the BSR30-Q series, which meets AEC-Q101 requirements and supports extended temperature and reliability validation.
How should the exposed collector pad be soldered for optimal thermal performance?
The exposed collector pad must be soldered to a ≥6 cm² copper area on the PCB using the reflow footprint shown in Figure 2 (sot089_fr). Tin-plated single-sided FR4 is specified; thermal vias beneath the pad are recommended to enhance heat transfer to internal or backside planes without violating the 13 K/W Rth(j-sp) specification.
What base resistor value is recommended for switching a 1 A load?
For full saturation at IC = −1 A, use hFE(min) = 40 and target IB ≥ 25 mA. With VBB = 3.3 V and VBEsat ≈ −1.0 V, RB ≤ (3.3 V − 1.0 V) / 0.025 A = 92 Ω. A standard 82 Ω, 0.125 W resistor provides sufficient drive while staying within power limits.
