Product details
Overview
BCP5310TA 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), hFE gain group 10 (25–160), and AEC-Q101 qualification for automotive reliability. It is used in medium-power switching applications such as relay drivers and linear regulators.
For engineers reviewing the BCP5310TA datasheet, BCP5310TA pinout, BCP5310TA application, or BCP5310TA equivalent, key selection criteria include its -80V breakdown rating, thermal resistance (RθJL = 19.4°C/W), gain group consistency, RoHS/Green compliance, and SOT223 mounting compatibility with standard PCB layouts.
Technical Context
The BCP5310TA is a silicon PNP transistor optimized for medium-power linear and switching operation. Its VCEO = -80 V and VCBO = -100 V support high-voltage load control, while its 2W power rating enables operation with minimal heatsinking on 50 mm × 50 mm 1 oz copper PCBs.
It delivers stable DC current gain (hFE = 25–160 at IC = -150 mA, VCE = -2 V) across -65°C to +150°C, with fT = 150 MHz enabling audio-frequency amplification and fast-switching response. ESD robustness (HBM = 4 kV) supports handling in industrial assembly environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -80 V - Maximum safe collector-emitter voltage before breakdown; enables use in 48V automotive and industrial supply rails. |
| IC (cont.) | -1 A - Continuous collector current capacity; supports driving relays, solenoids, or LED arrays without forced cooling. |
| VCE(sat) | ≤ -500 mV @ -500 mA / -50 mA - Low saturation loss reduces conduction heating and improves efficiency in switch-mode operation. |
| hFE Gain Group | 10 (25–160) - Tighter hFE spread than standard parts; simplifies bias design in production-amplifier stages. |
| RθJL | 19.4 °C/W - Junction-to-lead thermal resistance; allows direct solder-point thermal path to PCB copper for predictable derating. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per JESD22-A114/A115. |
Pinout & Package
SOT223 package: surface-mount, 4-pin (3 active + 1 thermal tab), molded green compound (UL 94V-0), matte tin-plated leads, 0.112 g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Main current exit terminal; connected to higher potential rail in PNP switching configurations. |
| 2 (Base) | B | Control input; requires ~-1.0 V VBE(on) to saturate at -500 mA collector current. |
| 3 (Collector) | C | Main current entry terminal; electrically tied to thermal tab for enhanced heat transfer to PCB copper. |
| 4 (Tab/Collector) | C (thermal) | Exposed metal pad - must be soldered to ≥50 mm² 1 oz copper pour to achieve RθJA = 62°C/W and full 2W rating. |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO (-80 V) | Enables direct interface with 24–48 V industrial bus systems without external voltage clamping. |
| Low VCE(sat) (≤ -500 mV) | Reduces power loss by >30% vs. standard PNP transistors at 500 mA, lowering thermal load on PCB layout. |
| Gain Group 10 (25–160) | Provides predictable base drive requirements across production lots, minimizing calibration in analog amplifier designs. |
| AEC-Q101 qualification | Validates performance over -40°C to +125°C ambient with PPAP documentation support for Tier-1 automotive programs. |
| Green, halogen-free construction | Meets IPC-1752A reporting requirements and EU Directive 2011/65/EU without compromising thermal or electrical performance. |
Applications
| Automotive Relay Driver | Industrial Linear Regulator Pass Element |
|---|---|

IC Role / Device Role / Timing Role: Current-source driver in push-pull pair; handles negative half-cycle of audio waveform. Use Value: fT = 150 MHz ensures flat frequency response to 20 kHz; low Cobo = 25 pF minimizes high-frequency instability. |
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 | Higher hFE gain group (100–250); otherwise identical ratings and package. | Better suited for low-base-drive circuits (e.g., microcontroller GPIO direct drive) where base current budget is constrained. | Select when precise low-current switching or improved current gain linearity at IC < 100 mA is required. |
| MBT3906DW1T1G | SOT363 package (dual), lower PD = 300 mW, VCEO = -40 V, no AEC-Q101 qualification. | Limited to low-power logic-level switching; unsuitable for automotive or >40 V applications. | Use only in space-constrained consumer electronics where voltage and power demands are significantly lower. |
Compared with BCP5310TA, BCP5316TA offers higher gain for reduced base drive but same thermal and voltage capability, while MBT3906DW1T1G trades off ruggedness and qualification for footprint reduction-making BCP5310TA optimal for cost-sensitive, thermally demanding automotive and industrial switches.

FAQ
What is the maximum allowable junction temperature for BCP5310TA?
The BCP5310TA has an absolute maximum junction temperature (TJ) of +150°C, with continuous operation specified from -65°C to +150°C. Derating begins above +25°C ambient at 16.1 mW/°C (based on RθJA = 62°C/W), and thermal shutdown is not built-in-external thermal monitoring is required for sustained high-power operation.
Can BCP5310TA replace BCP53TA in existing designs?
Yes-BCP5310TA is a direct replacement for BCP53TA, sharing identical electrical specifications, SOT223 package, pinout, and thermal characteristics. The "10" suffix denotes gain group 10 (hFE = 25–160), whereas BCP53TA is an ungrouped version with wider hFE variation (25–250); using BCP5310TA improves consistency in production bias networks.
Is the thermal tab (Pin 4) internally connected to the collector?
Yes-the exposed metal tab (Pin 4) is electrically and thermally connected to the collector terminal. It must be soldered to a dedicated PCB copper pour to achieve rated 2W power dissipation and RθJL = 19.4°C/W; floating or insulated mounting degrades thermal performance and risks premature failure.
Does BCP5310TA support pulse operation beyond its continuous IC rating?
Yes-it supports ICM = -2 A peak pulse current with duty cycle ≤ 2% and pulse width ≤ 300 µs, as verified in pulsed test conditions. This enables short-duration surge handling (e.g., relay pull-in, motor startup) without exceeding junction temperature limits when properly heatsinked.
