Product details
Overview
BCP53-16-QF from Nexperia is a PNP medium-power bipolar junction transistor in SOT223 (SC-73) package, rated for −80 V VCEO, −1 A continuous collector current, and 100–250 DC current gain (hFE) at VCE = −2 V and IC = −150 mA. It serves as a high-side switch or linear regulator pass element in automotive power management systems.
For engineers reviewing the BCP53-16-QF datasheet, BCP53-16-QF pinout, BCP53-16-QF application, or BCP53-16-QF equivalent, this device is selected for robust thermal performance on FR4 PCBs, AEC-Q101 qualification, and stable hFE across −55 °C to +150 °C ambient range in battery-driven and MOSFET driver circuits.
Technical Context
This PNP transistor operates in linear or saturated switching mode with VBE ≈ −1 V at IC = −500 mA and exhibits low VCE(sat) of ≤ −0.5 V at IC = −500 mA / IB = −50 mA. Its fT of 145 MHz supports moderate-speed switching applications.
Thermal design relies on mounting pad area: Rth(j-a) ranges from 93 K/W (6 cm² collector pad) to 192 K/W (standard footprint), enabling scalable power dissipation up to 1.35 W under optimized PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum safe collector-emitter voltage with base open; defines high-side switch blocking capability. |
| IC (continuous) | −1 A - Continuous DC collector current rating; sets maximum load drive capacity in linear regulators. |
| hFE | 100–250 at VCE = −2 V, IC = −150 mA - Confirmed current gain range ensures predictable base drive sizing. |
| Ptot | 1.35 W with 6 cm² copper pad - Achievable power dissipation enables thermally constrained automotive PCB designs. |
| fT | 145 MHz - Transition frequency supports switching above 100 kHz in active clamp or driver stages. |
| VCE(sat) | ≤ −0.5 V at IC = −500 mA, IB = −50 mA - Low saturation voltage minimizes conduction loss in high-side switches. |
| Rth(j-a) | 93 K/W (6 cm² pad) - Junction-to-ambient thermal resistance directly determines temperature rise under load. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads, 2.3 mm pitch, and 6.5 mm × 3.5 mm × 1.65 mm body dimensions; collector terminals (pins 2 and 4) provide dual thermal paths to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input requiring −50 mA peak base current for full saturation at −500 mA collector load. |
| 2 | Collector | Main current path terminal; electrically and thermally connected to large copper pour via exposed pad. |
| 3 | Emiter | Reference node tied to system high rail in high-side switch configuration; carries full load current. |
| 4 | Collector | Second collector connection-parallel path to pin 2-to reduce thermal resistance and improve power handling. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Stress-tested per automotive discrete semiconductor standard; suitable for under-hood and ADAS power modules. |
| Three hFE bins | BCP53-16-QF offers 100–250 hFE, enabling precise gain matching in parallel-output or feedback-critical linear regulators. |
| Dual-collector thermal design | Pins 2 and 4 both connect to collector, lowering effective Rth(j-a) by up to 30% vs. single-collector SOT223 variants. |
| High VCBO | −100 V collector-base rating allows safe operation with transient spikes exceeding nominal supply rails. |
| Low VBE | ≈ −1 V at IC = −500 mA reduces base drive power and eases compatibility with 3.3 V/5 V logic-level controllers. |
Applications
| Linear Voltage Regulators | High-Side Switches |

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 |
|---|---|---|---|
| BCP53-10-Q | hFE = 63–160 (lower mid-range gain); otherwise identical ratings and package. | Suitable where lower base drive sensitivity is acceptable, e.g., fixed-gain amplifiers with ample margin. | Select when tighter hFE tolerance is not required and cost optimization is prioritized. |
| ZTX951 | TO-92 package, −60 V VCEO, −1 A IC, hFE = 100–800; no AEC-Q101 qualification. | Limited to non-automotive industrial or consumer use due to lower voltage rating and lack of automotive qualification. | Choose only for prototyping or non-automotive production where SOT223 footprint is not mandatory. |
Compared with BCP53-10-Q, the BCP53-16-QF provides higher and more consistent hFE for precision biasing, while ZTX951 trades automotive reliability and thermal performance for through-hole assembly flexibility and wider gain spread.

FAQ
What is the maximum allowable junction temperature for BCP53-16-QF?
The absolute maximum junction temperature is 150 °C per IEC 60134. Operation above this threshold risks permanent degradation of hFE and increased leakage. Thermal design must ensure Tj = Tamb + (Pdiss × Rth(j-a)) remains below 150 °C under worst-case load and ambient conditions.
Is BCP53-16-QF pin-compatible with other SOT223 PNP transistors?
Yes-its 4-pin SOT223 (SC-73) outline matches industry-standard footprints. Pins 1 (B), 2 (C), 3 (E), and 4 (C) align with JEDEC MO-178AC, enabling drop-in replacement where thermal and gain requirements align, though hFE binning and AEC-Q101 status must be verified per application.
How does the dual-collector configuration affect PCB layout?
Pins 2 and 4 are internally shorted to the collector and must be soldered to the same large copper pour. This doubles thermal conduction area, reducing Rth(j-a) by up to 30% versus single-collector variants-requiring a minimum 6 cm² copper pad for rated 1.35 W dissipation.
Can BCP53-16-QF be used in avalanche mode?
No-it is not rated or characterized for controlled avalanche operation. The −80 V VCEO rating applies only under normal forward-active or saturation conditions; operation beyond this voltage risks irreversible breakdown, especially given its non-avalanche-rated construction and lack of energy absorption specifications.
