Product details
Overview
BCP5316TC from Diodes Incorporated is a PNP medium-power bipolar junction transistor in SOT223 package, rated for -80V VCEO, -1A continuous collector current, and 2W power dissipation. It features low saturation voltage (VCE(sat) ≤ -500 mV @ -500 mA), high DC current gain (hFE = 100–250, Gain Group 16), and AEC-Q101 qualification for automotive reliability. It is used in medium-power switching and audio output stages.
For engineers reviewing the BCP5316TC datasheet, BCP5316TC pinout, BCP5316TC application, or BCP5316TC equivalent, key selection criteria include its -80V breakdown rating, thermal resistance (RθJA = 62°C/W), gain group consistency, RoHS/Green compliance, and SOT223 thermal performance on 50 mm × 50 mm 1 oz copper PCBs.
Technical Context
This PNP transistor operates with emitter-grounded configuration and supports linear amplification and saturated switching. Its fT of 150 MHz enables use in AF driver stages up to several hundred kHz, while VBE(on) ≤ -1.0 V at -500 mA ensures predictable base drive requirements.
The device's thermal design relies on the SOT223 package's low RθJL (19.4°C/W) and defined mounting conditions-collector lead soldered to 50 mm × 50 mm 1 oz copper on FR4-to sustain 2W dissipation at TA ≤ +70°C per derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -80 V - Maximum safe collector-emitter voltage before avalanche; enables use in 48V automotive supply rails with margin. |
| IC (continuous) | -1 A - Supports sustained load switching or amplification up to 1 W into 8 Ω loads in Class-A/B audio output. |
| PD | 2 W - Achievable only with proper PCB copper area (50 mm × 50 mm 1 oz Cu); requires thermal layout verification. |
| hFE (Gain Group 16) | 100–250 @ IC = -150 mA - Tight gain distribution simplifies bias network design in production amplifiers. |
| VCE(sat) | ≤ -500 mV @ IC = -500 mA, IB = -50 mA - Ensures < 0.25 W conduction loss in saturated switch mode. |
| fT | 150 MHz - Supports stable operation in audio driver circuits with bandwidth > 20 kHz and moderate slew rate demands. |
Pinout & Package
SOT223 package with exposed collector tab for thermal conduction; molded green plastic case (UL 94V-0), matte tin-plated leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current source terminal; connected to higher potential in PNP operation; requires low-impedance return path. |
| 2 (Base) | B | Control input; driven negative relative to emitter to turn on; typical IB = -50 mA for full saturation. |
| 3 (Collector) | C | Main current sink; electrically and thermally tied to large copper pad; primary heat path to PCB. |
| 4 (Collector Tab) | C (thermal) | Exposed metal tab-must be soldered to ≥50 mm² copper pour for rated 2W dissipation and RθJA = 62°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature range (-65°C to +150°C) and reliability stress tests (HTOL, TC, HAST). |
| Green / Halogen-free | Meets <900 ppm Br, <900 ppm Cl (<1500 ppm total Br+Cl), <1000 ppm Sb; compliant with JEDEC J-STD-709C. |
| High gain consistency (Group 16) | hFE = 100–250 at IC = -150 mA ensures uniform biasing across production batches in multi-channel amps. |
| Low VCE(sat) | ≤ -500 mV at IC = -500 mA reduces conduction loss by >30% vs. standard PNP transistors with VCE(sat) > -700 mV. |
Applications
| Automotive Door Module Switching | Industrial Relay Driver |
|---|---|
Use Scenario: Driving 12V/24V solenoid loads in vehicle door lock actuators under pulsed duty cycles. IC Role / Device Role / Timing Role: PNP high-side switch controlling ground-return solenoid current via emitter-follower configuration.

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 |
|---|---|---|---|
| BCP5316TA | Same electrical specs and gain group; differs only in tape-and-reel packaging (1,000 pcs vs. 4,000 pcs) and 7″ vs. 13″ reel size. | Identical functional use; selected when smaller reels align with SMT line changeover frequency or inventory turnover. | Choose TA for pilot builds or low-volume production; TC preferred for high-volume automated assembly. |
| BCP53QTA | Automotive-grade variant with identical absolute max ratings and electrical characteristics; marked "Q" for PPAP-capable automotive traceability. | Required for Tier-1 automotive programs needing full PPAP documentation and lot-level traceability; not needed for industrial use. | Select QTA only when OEM mandates PPAP submission; BCP5316TC satisfies AEC-Q101 but lacks Q-marked traceability. |
Compared with BCP5316TA and BCP53QTA, the BCP5316TC offers identical transistor performance and AEC-Q101 qualification, but provides cost-efficient high-volume packaging (4,000 pcs/reel) without automotive-specific traceability overhead-ideal for industrial and consumer applications requiring reliability without PPAP bureaucracy.

FAQ
What is the maximum allowable junction temperature for BCP5316TC?
The BCP5316TC has an operating junction temperature range of -65°C to +150°C. Its absolute maximum TJ is +150°C; sustained operation above this limit risks parametric shift or permanent failure. Derating begins at +25°C ambient, with full 2W power limited to ≤ +70°C TA on specified PCB layout.
Is BCP5316TC pin-compatible with BCP54 or other complementary NPN transistors?
No-BCP5316TC (PNP) and BCP54 (NPN) share the same SOT223 package outline and pin assignment (E-B-C-tab), but their polarity and biasing requirements differ fundamentally. They are complementary *types*, not drop-in replacements; circuit redesign is required when swapping between PNP and NPN devices.
Does BCP5316TC require a heatsink in standard SOT223 mounting?
No external heatsink is required if mounted per datasheet guidelines: collector tab soldered to ≥50 mm² of 1 oz copper on FR4 PCB. Under those conditions, RθJA = 62°C/W allows 2W dissipation at TA = +70°C. Smaller copper areas or still-air enclosures necessitate derating or supplemental cooling.
How does the "16" in BCP5316TC denote gain grouping?
The "16" indicates Gain Group 16, specifying hFE = 100–250 at IC = -150 mA and VCE = -2 V. This tighter binning improves predictability in production bias networks versus standard "10" group (hFE = 63–160), reducing calibration effort in multi-channel amplifier designs.
