Product details
Overview
BC53-16PA,115 from Nexperia is a PNP medium power transistor in an ultra-thin leadless SOT1061 package, rated for −80 V VCEO, −1 A continuous collector current, and 100–250 DC current gain (hFE) at −150 mA/−2 V. It serves as a high-side switch or linear regulator pass element in battery-powered industrial control modules requiring robust thermal performance and AEC-Q101-aligned reliability.
For engineers reviewing the BC53-16PA,115 datasheet, BC53-16PA,115 pinout, BC53-16PA,115 application, or BC53-16PA,115 equivalent, key selection criteria include its exposed heatsink thermal path, pulsed peak current capability of −2 A, and precise hFE binning for predictable bias stability in analog feedback loops.
Technical Context
This device operates as a medium-power PNP bipolar junction transistor with fixed emitter-base and collector-base junction architecture. Its design centers on high-current switching and linear amplification under sustained thermal load, enabled by an exposed collector pad that directly interfaces with PCB copper for low Rth(j-sp) (20 K/W).
The BC53-16PA variant is binned for hFE = 100–250 at −150 mA and −2 V, distinguishing it from BC53-10PA (63–160) and standard BC53PA (63–250). It supports pulsed operation up to 300 µs with 2% duty cycle and delivers fT = 145 MHz at −50 mA/−5 V, confirming suitability for moderate-speed switching and audio-frequency amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum safe collector-emitter voltage with open base; defines upper rail tolerance in high-side switch configurations. |
| IC | −1 A - Continuous DC collector current rating; supports 1 W+ dissipation when mounted on 4-layer PCB with 1 cm² collector pad. |
| hFE | 100–250 at −150 mA/−2 V - Tight DC current gain bin ensures consistent base drive requirements across production units. |
| VCE(sat) | −0.5 V max at −500 mA/−50 mA - Low saturation voltage minimizes conduction loss in linear regulators and power switches. |
| fT | 145 MHz - Transition frequency confirms usable bandwidth for audio amplification and <100 kHz PWM gate driving. |
| Rth(j-sp) | 20 K/W - Junction-to-solder-point thermal resistance enables rapid heat transfer to PCB, critical for compact power designs. |
| Cc | 15 pF - Collector capacitance limits high-frequency Miller effect, supporting stable operation in feedback circuits. |
Pinout & Package
Package: SOT1061 - ultra-thin (0.65 mm max height), leadless, 2 mm × 2 mm body with exposed collector thermal pad. Dimensions comply with JEDEC MO-317.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires ≤−0.3 A peak base drive; connects to driver IC or resistor-biased control logic. |
| 2 | Emitter (E) | Common reference terminal for PNP operation; tied to positive supply rail in high-side switch topologies. |
| 3 | Collector (C) | Main power output node with exposed metal pad; must be soldered to ≥1 cm² copper area for rated thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Exposed collector thermal pad | Enables 1.65 W total power dissipation on 4-layer FR4 with 1 cm² mounting pad-doubles thermal capacity vs. standard SOT packages. |
| Three hFE gain bins | BC53-16PA's 100–250 range allows precise matching in differential pairs or current mirrors without external trimming. |
| AEC-Q101 qualification (legacy) | Validated per Stress Test Qualification for Discrete Semiconductors-supports automotive-grade BOM continuity despite current non-automotive status. |
| Pulsed ICM = −2 A | Supports short-duration surge loads (≤1 ms) in motor start-up or inrush limiting circuits without derating. |
| Ultra-thin 0.65 mm profile | Reduces board stack height in space-constrained IoT sensors and wearable power management modules. |
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 |
|---|---|---|---|
| BCP53-16,115 | Same SOT1061 package and hFE bin (100–250), but rated for −45 V VCEO and −1.5 A IC; lower voltage headroom, higher current. | Preferred in 24 V systems where −45 V suffices and higher IC margin is needed; unsuitable for 48 V or load-dump tolerant designs. | Select BCP53-16,115 only if system rail voltage stays ≤36 V and thermal design accommodates higher IC derating. |
| BC807-16,215 | SOT23 package, −45 V VCEO, −500 mA IC, same hFE bin; no exposed thermal pad; Rth(j-a) = 300 K/W vs. 76 K/W for BC53-16PA. | Fits ultra-compact layouts but limited to ≤300 mW continuous dissipation; not viable for >300 mA linear regulation. | Choose BC807-16,215 only for signal-level switching or low-power bias networks where board space outweighs thermal needs. |
Compared with BC53-16PA,115, BCP53-16,115 trades voltage rating for higher current and identical thermal packaging, while BC807-16,215 sacrifices power handling and thermal performance for footprint reduction-making BC53-16PA the optimal balance for 48 V-tolerant, medium-power linear and switching roles.

FAQ
Is BC53-16PA,115 qualified for automotive use?
No-although originally AEC-Q101 qualified, revision history confirms BC53PA series was reclassified as non-automotive as of Rev. 11 (2025). It remains suitable for industrial and commercial applications with equivalent stress testing, but automotive designs require verified -Q variants such as PBSS4041T,115.
What is the maximum allowable PCB copper area for the collector pad?
The datasheet specifies five mounting configurations; the highest-rated thermal performance (1.65 W Ptot) requires a 4-layer FR4 PCB with a 1 cm² tin-plated collector pad. Using less copper reduces power handling-e.g., single-sided 1 cm² yields only 0.42 W.
How does the hFE binning affect base resistor selection?
With hFE = 100–250 at −150 mA, base current must be designed for worst-case gain (100) to guarantee saturation. For −500 mA IC, minimum IB = −5 mA ensures robust turn-on across all units, avoiding partial conduction and thermal runaway.
Can BC53-16PA,115 replace BC53-10PA in existing designs?
Yes-both share identical package, pinout, voltage/current ratings, and thermal characteristics; the only difference is hFE range (100–250 vs. 63–160). Substituting BC53-16PA may reduce required base drive and improve loop stability in gain-sensitive circuits, but verify bias point margins.
