Product details
Overview
BC817DPN from Nexperia is a dual NPN/PNP general-purpose transistor pair in a single SOT457 (SC-74/TSOP6) surface-mount package, rated for 45 V VCEO, 500 mA continuous collector current per transistor, and AEC-Q101 qualified for automotive use. It serves as a compact, cost-optimized solution for complementary switching and amplification in space-constrained PCBs.
For engineers reviewing the BC817DPN datasheet, BC817DPN pinout, BC817DPN application, or BC817DPN equivalent, key selection criteria include its matched NPN/PNP pairing, 160–400 hFE range at 100 mA, 700 mV VCEsat (NPN), and thermal resistance of 208 K/W in free air - all critical for bidirectional signal control and low-power logic interfacing.
Technical Context
This dual transistor integrates one NPN (TR1) and one PNP (TR2) device sharing a common 6-pin SOT457 footprint. Each transistor operates independently with separate emitter, base, and collector terminals - no internal connection between devices. Pin assignment follows standardized SC-74 layout with TR1's C1/B1/E1 and TR2's C2/B2/E2 assigned to pins 6/2/1 and 3/5/4 respectively.
Electrical behavior is characterized by temperature-stable hFE (160–400 at 100 mA), low saturation voltage (≤700 mV for NPN, ≤800 mV for PNP), and transition frequencies of 100 MHz (NPN) and 80 MHz (PNP). Thermal performance is defined for FR4 PCB mounting with 1 cm² copper pad, enabling reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V maximum - supports rail-to-rail switching in 24 V automotive and industrial control circuits without breakdown risk |
| IC (continuous) | 500 mA per transistor - sufficient for driving small relays, LEDs, or logic-level MOSFET gates |
| hFE | 160–400 at VCE = 1 V, IC = 100 mA - enables predictable DC biasing in amplifier and switch configurations |
| VCEsat | ≤700 mV (NPN), ≤800 mV (PNP) at IC/IB = 10 - minimizes conduction loss and self-heating in saturated switching |
| fT | 100 MHz (NPN), 80 MHz (PNP) - suitable for audio-frequency amplification and low-speed digital signal inversion |
| Ptot (device) | 600 mW on FR4 PCB - defines safe power handling with standard board layout and no heatsink required |
| Rth(j-a) | 208 K/W in free air - informs thermal design margin when ambient exceeds 70 °C |
Pinout & Package
SOT457 (SC-74/TSOP6) plastic surface-mount package: 6-lead, 1.7 mm × 2.5 mm body, 0.65 mm pitch, 1.3 mm height, with pin 1 index marking. Designed for reflow and wave soldering per IPC-7351B standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR2 (PNP) | Current sink terminal for PNP transistor; connects to load return path in high-side switch designs |
| 2 | Base of TR1 (NPN) | Control input for NPN transistor; requires ~50 mA drive for full saturation at 500 mA load |
| 3 | Collector of TR2 (PNP) | High-side switching node; connects to positive supply rail in complementary output stages |
| 4 | Emitter of TR2 (PNP) | Redundant emitter connection - identical to Pin 1; used for mechanical stability and thermal relief |
| 5 | Base of TR2 (PNP) | Control input for PNP transistor; polarity inverted relative to TR1, enabling push-pull operation |
| 6 | Collector of TR1 (NPN) | Low-side switching node; connects to ground-referenced loads such as sensors or indicator LEDs |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
| Complementary NPN/PNP pairing | Enables single-package push-pull, phase-splitter, or level-shifting circuits without discrete matching |
| Reduced component count | Replaces two discrete transistors and associated passives, cutting BOM cost and PCB area by ≥35% |
| Thermal derating support | Specified Rth(j-a) and Ptot values allow accurate junction temperature estimation under real-world PCB conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary bipolar transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BDW1T3G | Higher hFE (200–450), same SOT363 package but lower VCEO (45 V vs. 50 V for PNP), non-AEC-Q101 | Limited to commercial-temperature industrial use; lacks automotive qualification and thermal derating data | Select when higher DC gain is prioritized over automotive compliance and thermal margin |
| MBT3904DW1T3G | Lower VCEO (40 V), higher fT (300 MHz), same SOT363, non-AEC-Q101, no PNP complement | Single NPN only - requires external PNP for complementary operation, increasing board area and BOM count | Select only for high-frequency NPN-only amplification where PNP functionality is unnecessary |
Compared with BC847BDW1T3G and MBT3904DW1T3G, the BC817DPN uniquely delivers AEC-Q101 qualification, matched NPN/PNP pairing in one package, and verified thermal performance on FR4 - making it the only choice for automotive-compliant, space-constrained bidirectional switching.

FAQ
What is the maximum operating temperature for BC817DPN in continuous use?
The BC817DPN has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. When mounted on an FR4 PCB with 1 cm² copper pad, its thermal resistance is 208 K/W, allowing continuous operation at full 500 mA load up to 70 °C ambient - beyond which derating is required per the datasheet's thermal curves.
Can BC817DPN replace two separate BC847 and BC857 transistors?
Yes - the BC817DPN integrates one NPN (equivalent to BC847) and one PNP (equivalent to BC857) in a single SOT457 package with identical pinout mapping for each transistor. Its hFE range (160–400), VCEO (45 V), and IC (500 mA) match both devices, and AEC-Q101 qualification exceeds the commercial-grade BC847/BC857 specifications.
How is the pin numbering oriented on the BC817DPN package?
With the marking side up and the pin 1 index notch or dot at the left end, pins are numbered left-to-right: Pin 1 (E2), Pin 2 (B1), Pin 3 (C2), Pin 4 (E2), Pin 5 (B2), Pin 6 (C1). This matches the SC-74 outline in Figure 9 of the Nexperia datasheet, where the index mark aligns with Pin 1 and the body tapers toward Pin 6.
Does BC817DPN support pulsed operation beyond its DC ratings?
Yes - the BC817DPN supports peak collector current (ICM) of 1 A for single pulses ≤1 ms, and peak base current (IBM) of 200 mA under the same condition. These values are validated per IEC 60134 limiting values and appear in Table 5 of the datasheet, enabling short-duration overload handling in motor startup or surge protection circuits.
