Product details
Overview
BCW68HVL from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 (TO-236AB) package, rated for −45 V VCEO, −800 mA IC, and 250–600 hFE at −100 mA collector current; it delivers low VCE(sat) (−350 mV typ.) and supports automotive-grade switching in power management and signal amplification circuits.
For engineers reviewing the BCW68HVL datasheet, BCW68HVL pinout, BCW68HVL application, or BCW68HVL equivalent, this page provides verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, and real-world use cases in automotive body electronics, industrial control interfaces, and consumer power sequencing.
Technical Context
This PNP BJT operates in linear or saturated switching mode with base-controlled current gain; its hFE range (250–600) enables stable biasing across temperature (−55 °C to +150 °C), and pulsed ICM of −1 A supports short-duration load switching.
The device features low thermal resistance (Rth(j-a) = 500 K/W on FR4 PCB), defined saturation voltages (VCE(sat) ≤ −450 mV at −500 mA), and AEC-Q101 qualification-confirming suitability for automotive ambient and reliability requirements without external qualification overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V: Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit in high-side switch designs. |
| IC | −800 mA continuous: Sustained current-handling capability for relay drivers, LED arrays, and fan controllers. |
| hFE | 250–600 at VCE = −1 V, IC = −100 mA: Enables predictable base drive sizing for stable DC bias networks. |
| VCE(sat) | −350 mV typ. at IC = −100 mA, IB = −10 mA: Minimizes conduction loss in low-voltage switching applications. |
| Ptot | 250 mW at Tamb ≤ 25 °C: Sets thermal design boundary for PCB copper area and airflow requirements. |
| Rth(j-a) | 500 K/W on FR4: Quantifies junction-to-ambient thermal path for derating calculations per Figure 1. |
| AEC-Q101 | Qualified: Confirmed stress-test compliance for automotive discrete semiconductors; no additional qualification needed. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; compact 2.9 mm × 1.3 mm footprint, 1.1 mm height, and standard reflow-compatible pad layout (Figure 16).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires series resistor to limit IB ≤ −100 mA (DC) or −200 mA (pulse). |
| 2 | Emitter (E) | Common reference terminal; connected to higher potential rail in PNP high-side switch configurations. |
| 3 | Collector (C) | Output current sink; ties to load return path; must remain ≤ −45 V relative to emitter under all operating conditions. |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain | hFE up to 600 ensures minimal base drive current for efficient switching in battery-powered systems. |
| Automotive qualification | AEC-Q101 compliance validates performance across −40 °C to +125 °C ambient and lifetime vibration/shock stress. |
| Low saturation voltage | VCE(sat) ≤ −450 mV at −500 mA enables <100 mW conduction loss in 5 V rail switching nodes. |
| Thermal robustness | 150 °C max junction temperature and defined derating curve support operation in enclosed automotive ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCW68H | Same die, identical electrical specs; differs only in marking code (EV% vs VL) and internal lot traceability. | No functional difference; both qualified to AEC-Q101 and share full pinout/package compatibility. | Select BCW68HVL when explicit VL suffix is required for OEM BOM compliance or regional sourcing mandates. |
| MMBT3906LT1G | Lower hFE (30–300), lower IC (−200 mA), same SOT23 package; not AEC-Q101 qualified. | Suitable for non-automotive consumer logic-level inversion but lacks thermal and reliability margin for under-hood use. | Choose only for cost-sensitive, non-automotive designs where −45 V/−800 mA rating and AEC-Q101 are unnecessary. |
Compared with BCW68HVL, BCW68H offers identical performance with alternate traceability, while MMBT3906LT1G trades automotive qualification and current capacity for lower unit cost in benign environments.

FAQ
Is BCW68HVL pin-compatible with BCW66 series NPN transistors?
No. BCW68HVL is a PNP device with Base–Emitter–Collector pinout (1–2–3), while BCW66F/G/H are NPN with Collector–Base–Emitter (1–2–3) in the same SOT23 package. Swapping them without circuit redesign causes polarity inversion and potential damage.
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current is −100 mA (Table 5). For reliable long-term operation, keep IB ≤ −10 mA at IC = −100 mA to maintain hFE within 250–600 and avoid thermal runaway at elevated ambient temperatures.
Can BCW68HVL be used in linear amplifier configurations?
Yes-its hFE stability across IC (Figures 3–5) and low VCE(sat) support Class-A and AB small-signal amplification, though its primary design intent is switching. Avoid operation near VCEO limit in linear mode due to secondary breakdown risk.
Does BCW68HVL require heatsinking in typical SMT applications?
No external heatsink is needed for ≤250 mW dissipation at Tamb ≤ 25 °C. At 70 °C ambient, power must be derated to ~125 mW (per Figure 1); adequate 1 oz. copper pour under pin 2 (emitter) suffices for most automotive and industrial layouts.
