Product details
Overview
BC53-16PA-7 from Diodes Incorporated is a PNP medium-power transistor in a U-DFN2020-3 (Type B) package, rated for -80 V VCEO, -1 A continuous collector current, and 520 mW power dissipation. It delivers low saturation voltage (< -500 mV at -0.5 A) and supports automotive-grade reliability per AEC-Q101, making it suitable for AF driver stages and medium-power switching in compact DC-DC converters.
For engineers reviewing the BC53-16PA-7 datasheet, BC53-16PA-7 pinout, BC53-16PA-7 application, or BC53-16PA-7 equivalent, key selection criteria include verified VCEO/IC ratings, thermal resistance (RθJA = 240 °C/W), complementary NPN pairing with BC56-16PA, and AEC-Q101 qualification for automotive signal conditioning circuits.
Technical Context
This PNP bipolar junction transistor operates in linear amplification and saturated switching modes, with hFE ranging from 25 to 250 across IC = -5 mA to -500 mA at VCE = -2 V. Its fT of 125 MHz enables use in audio-frequency amplification up to ~100 kHz with stable gain.
The device uses a planar epitaxial die structure with emitter ballasting for current uniformity. Thermal performance is defined for minimum-copper FR4 PCB mounting, where RθJL = 20 °C/W ensures efficient heat transfer from junction to solder point under pulsed operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -80 V - Maximum safe collector-emitter voltage before breakdown in open-base configuration |
| IC (cont.) | -1 A - Continuous DC collector current limit at TA = 25 °C with derating above 25 °C |
| PD | 520 mW - Max steady-state power dissipation on standard FR4 PCB with 1 oz copper |
| VCE(sat) | < -500 mV @ -0.5 A / -50 mA - Ensures low conduction loss in switching applications |
| fT | 125 MHz - Supports high-fidelity audio amplification and fast switching transitions |

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 |
|---|---|---|---|
| BC807-16-7 | Slightly lower VCEO (-45 V), same hFE range, SOT-23 package | Not AEC-Q101 qualified; unsuitable for automotive under-hood use | Select only for cost-sensitive consumer applications with <45 V rail requirements |
| MMBT5401-7-F | Higher VCEO (-160 V), lower IC (-200 mA), SOT-23 package | Better for high-voltage, low-current switching; not suitable for 1 A load switching | Prefer when circuit requires >80 V blocking but lower power dissipation |
Compared with BC807-16-7 and MMBT5401-7-F, BC53-16PA-7 uniquely balances AEC-Q101 compliance, -1 A current capability, and -80 V breakdown in a 2.0×2.0 mm DFN-making it optimal for space-constrained automotive and industrial switching where both voltage headroom and thermal density matter.

FAQ
What is the maximum operating temperature for BC53-16PA-7?
The BC53-16PA-7 has an operating junction temperature range of -65 °C to +150 °C, validated per AEC-Q101. Its storage temperature matches this range. Derating begins above 25 °C ambient, with power dissipation reduced linearly beyond that point based on RθJA = 240 °C/W.
Is BC53-16PA-7 compatible with lead-free reflow processes?
Yes. BC53-16PA-7 features matte tin-plated terminals and is qualified for standard lead-free reflow profiles (JEDEC J-STD-020 Level 1), including peak temperatures up to 260 °C. Its U-DFN2020-3 package is rated for moisture sensitivity level 1, eliminating bake requirements prior to assembly.
How does BC53-16PA-7 compare to its NPN complement BC56-16PA?
BC53-16PA-7 (PNP) and BC56-16PA (NPN) share identical package, thermal specs, voltage ratings, and current capabilities, with matched hFE ranges and saturation voltages. This symmetry enables balanced push-pull designs and simplifies layout in dual-transistor configurations like H-bridges or complementary amplifiers.
Can BC53-16PA-7 be used in linear regulator pass elements?
No. While BC53-16PA-7 supports linear amplification, its 520 mW power dissipation limit and lack of integrated thermal shutdown make it unsuitable as a standalone pass transistor in adjustable linear regulators. It may serve in pre-regulator or error-amplifier roles where power dissipation remains below 300 mW under worst-case load and dropout conditions.
