Product details
Overview
BC817DPN from Nexperia is an AEC-Q101-qualified NPN/PNP dual general-purpose transistor pair in a single SOT457 (SC-74/TSOP6) surface-mount package. It delivers 45 V VCEO, 500 mA continuous collector current per transistor, and DC current gain (hFE) of 160–400 at IC = 100 mA, enabling compact dual-polarity switching in automotive body control modules.
For engineers reviewing the BC817DPN datasheet, BC817DPN pinout, BC817DPN application, or BC817DPN equivalent, key selection criteria include verified dual-transistor polarity configuration, thermal resistance (Rth(j-a) = 208 K/W on FR4), AEC-Q101 qualification status, and SC-74 package footprint compatibility with automated placement.
Technical Context
This device integrates one NPN (TR1) and one PNP (TR2) silicon planar transistor in a monolithic-structure-free, discrete-die co-packaged assembly. Each transistor operates independently with separate emitter, base, and collector terminals - no internal connection between TR1 and TR2.
It supports pulsed operation up to 1 A peak collector current (tp ≤ 1 ms) and maintains hFE stability across −55 °C to +150 °C ambient, with VCE(sat) ≤ 700 mV at IC = 500 mA / IB = 50 mA for both polarities.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V per transistor - defines maximum safe voltage across collector-emitter under open-base condition for both NPN and PNP devices |
| IC | 500 mA continuous - maximum DC collector current each transistor handles without derating at Tamb ≤ 25 °C |
| hFE | 160–400 at VCE = 1 V, IC = 100 mA - usable DC current gain range for linear amplification or saturated switching design |
| Ptot | 600 mW per device on FR4 PCB - total power dissipation limit with specified 1 cm² copper pad, governing thermal layout requirements |
| fT | 100 MHz (NPN), 80 MHz (PNP) - transition frequency confirming suitability for low-speed digital switching and audio-frequency amplification |
| Rth(j-a) | 208 K/W - junction-to-ambient thermal resistance in free air, critical for estimating temperature rise in unforced convection environments |
Pinout & Package
SOT457 (SC-74/TSOP6) is a 6-pin, leadless, surface-mount plastic package with 0.95 mm pin pitch and 3.0 × 1.7 mm body size. The package supports reflow and wave soldering per Figures 10 and 11 in the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 (NPN) | Low-impedance current sink node for NPN transistor; connects to ground or low-side load return path |
| 2 | Base of TR1 (NPN) | Control input for NPN switch/amplifier; requires ~50 mA drive for full saturation at 500 mA load |
| 3 | Collector of TR2 (PNP) | High-side current source node for PNP transistor; connects to positive rail or load supply |
| 4 | Emitter of TR2 (PNP) | Current source output terminal for PNP; ties to VCC or high-side load connection |
| 5 | Base of TR2 (PNP) | Inverted control input for PNP; active-low logic interface compatible with microcontroller GPIO |
| 6 | Collector of TR1 (NPN) | Low-side switched output node for NPN; drives loads referenced to ground or negative rail |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and lighting modules per stress test standard for discrete semiconductors |
| Dual NPN/PNP topology | Enables complementary push-pull or H-bridge driver stages without inter-device matching or layout asymmetry |
| Reduced pick-and-place count | Single placement operation replaces two discrete transistors, lowering SMT line cycle time and feeder setup complexity |
| Thermal performance on FR4 | 600 mW total dissipation with 1 cm² copper pad meets industrial ambient requirements without heatsinking |
Applications
| Automotive Door Module | Industrial IO Expander |
|---|---|

Use Value: Single-package solution reduces board area by 40% vs. discrete equivalents while preserving timing margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN/PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BDW1T1G | Higher hFE (200–450), same SOT363 package but lower VCEO (45 V → 45 V), not AEC-Q101 qualified | Lacks automotive qualification; suitable only for commercial-grade consumer electronics | Select when AEC-Q101 is not required and tighter hFE tolerance is needed for analog biasing |
| MBT3904DW1T1G | Lower VCEO (40 V), higher fT (300 MHz), same SOT363, not AEC-Q101 qualified | Not rated for automotive underhood temperatures; limited to ≤125 °C junction operation | Prefer for high-frequency switching above 50 MHz where gain-bandwidth product outweighs voltage margin |
Compared with BC817DPN, BC847BDW1T1G offers improved DC gain consistency but lacks automotive qualification, while MBT3904DW1T1G trades voltage headroom and thermal robustness for RF performance - making BC817DPN the sole choice for AEC-Q101-compliant dual-transistor functions in harsh environments.

FAQ
Is BC817DPN pin-compatible with BC847BDW?
No. BC817DPN uses SOT457 (6-pin) with interleaved NPN/PNP pinout (E1-B1-C2-E2-B2-C1), while BC847BDW uses SOT363 (6-pin) with mirrored dual-NPN pinout (B1-C1-E1-B2-C2-E2). Physical pin mapping and internal polarity differ - direct replacement requires PCB redesign.
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is 200 mA (single pulse, tp ≤ 1 ms), but for continuous DC operation, base current must be limited to ensure IC ≤ 500 mA and junction temperature remains ≤150 °C. At IC = 500 mA and hFE ≥ 40, IB ≤ 12.5 mA is recommended for reliable saturation without thermal runaway.
Does BC817DPN support bidirectional signal switching?
No. BC817DPN contains two unidirectional bipolar junction transistors (one NPN, one PNP); neither transistor supports true bidirectional current flow like a MOSFET analog switch. It enables complementary unidirectional control (e.g., high-side PNP + low-side NPN), not AC signal routing.
Can BC817DPN replace two separate BC817-40 transistors?
Yes, functionally - but not mechanically. BC817DPN integrates one NPN (matching BC817-40 specs) and one PNP (BC807-40 equivalent) in one package. It replaces two discrete SOT23 devices, reducing board area and placement cost, though pinout and layout differ significantly from dual-SOT23 solutions.
