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-effective solution for complementary switching and amplification in power management and signal routing circuits.
For engineers reviewing the BC817DPN datasheet, BC817DPN pinout, BC817DPN application, or BC817DPN equivalent, key selection criteria include its dual-transistor topology, matched hFE range (160–400 at IC = 100 mA), thermal resistance (208 K/W), and automotive qualification - critical for space-constrained, reliability-sensitive designs.
Technical Context
This device integrates one NPN (TR1) and one PNP (TR2) transistor in a monolithic die with shared thermal path, enabling complementary push-pull operation without discrete pairing. Each transistor supports independent biasing, with verified DC current gain, saturation voltage, and transition frequency (fT = 100 MHz for NPN, 80 MHz for PNP) under defined test conditions.
It operates across −65 °C to +150 °C ambient temperature, with absolute maximum ratings including VCBO = 50 V (PNP), VEBO = 5 V, and Ptot = 600 mW (device-level, FR4 PCB mounted), ensuring robustness in automotive engine control and body electronics environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V max per transistor - defines safe blocking voltage in switch-off state for both NPN and PNP sections |
| IC | 500 mA continuous - sets maximum steady-state load current handling capability per transistor |
| hFE | 160–400 at VCE = 1 V, IC = 100 mA - enables predictable base drive sizing for linear or saturated switching |
| VCE(sat) | ≤ 700 mV at IC = 500 mA, IB = 50 mA - ensures low conduction loss in saturated switching applications |
| fT | 100 MHz (NPN), 80 MHz (PNP) - supports high-speed digital switching up to ~10–20 MHz practical edge rates |
| Ptot | 600 mW (device-level, FR4 PCB) - determines thermal derating requirements for sustained power dissipation |
| AEC-Q101 | Qualified - confirms stress-test compliance for automotive under-hood and chassis applications |
Pinout & Package
Package: SOT457 (SC-74 / TSOP6), 6-pin plastic surface-mount package with 0.95 mm pitch, 3.0 × 1.7 mm footprint, and exposed collector pad for thermal enhancement on FR4 PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 (NPN) | Low-side current return path for NPN transistor; referenced to ground in common-emitter configuration |
| 2 | Base of TR1 (NPN) | Control input for NPN section; requires ~1.2 V forward bias and current-limited drive |
| 3 | Collector of TR2 (PNP) | High-side current source terminal for PNP transistor; connects to positive rail in complementary pairs |
| 4 | Emitter of TR2 (PNP) | Current source return for PNP; typically tied to VCC or load supply in high-side switch layouts |
| 5 | Base of TR2 (PNP) | Inverted control input for PNP section; active-low logic interface compatible with microcontroller outputs |
| 6 | Collector of TR1 (NPN) | Primary output node for NPN; used for low-side switching, current sinking, or amplifier output stage |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN/PNP topology | Reduces board area and assembly steps by integrating complementary transistors in one package |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Matched hFE range | 160–400 per transistor enables consistent gain matching in differential or push-pull stages |
| Low VCE(sat) | ≤ 700 mV at full 500 mA load minimizes power loss and self-heating in switching regulators |
| Thermal performance | Rth(j-a) = 208 K/W on FR4 allows >250 mW usable power before exceeding 150 °C junction limit |
Applications
| Automotive Door Module | Industrial PLC Output Stage |

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 (onsemi) | Same SOT363 package; hFE range 200–450 but no AEC-Q101 qualification; lower Ptot (300 mW) | Limited to commercial-temperature industrial or consumer use; unsuitable for automotive under-hood | Select when AEC-Q101 is not required and smaller footprint (SOT363 vs SOT457) is prioritized |
| MBT3904DW1T1G (onsemi) | SOT363 package; NPN/NPN dual only; no PNP section; VCEO = 40 V; hFE = 100–300 | Cannot replace complementary switching functions; requires external PNP for push-pull topologies | Choose only for NPN-only dual amplification or switching where polarity symmetry is unnecessary |
Compared with BC817DPN, BC847BDW1T1G offers tighter hFE tolerance but lacks automotive qualification and thermal headroom, while MBT3904DW1T1G omits the PNP transistor entirely - making BC817DPN uniquely suited for space-constrained, automotive-grade complementary switching.

FAQ
Is BC817DPN pin-compatible with BC847BDW1T1G?
No. BC817DPN uses SOT457 (6-pin) with pinout E1-B1-C2-E2-B2-C1, while BC847BDW1T1G uses SOT363 (6-pin) with pinout E1-B1-C1-E2-B2-C2. The collector/emitter assignments differ, and the internal transistor types (NPN/PNP vs NPN/NPN) are incompatible for direct substitution.
What is the maximum allowable base current for continuous operation?
The peak base current rating 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 hFE = 160, this implies IB ≤ 3.1 mA for full 500 mA collector drive - actual design should include safety margin and thermal derating.
Can BC817DPN be used in linear amplifier mode?
Yes. Its hFE stability (160–400), low VCE(sat), and specified characteristics at VCE = 1 V support Class-A and Class-AB small-signal amplification. However, power dissipation must remain within 600 mW (device-level) with appropriate heatsinking on FR4 PCB to avoid thermal runaway.
Does BC817DPN have built-in ESD protection?
No. The datasheet does not specify integrated ESD protection diodes. External TVS or series resistors are recommended for I/O pins in systems exposed to human contact or cable discharge events, especially in automotive environments where ISO 10605 compliance may be required.
