Product details
Overview
PBHV8140Z,115 from Nexperia is an NPN high-voltage low-VCEsat transistor in SOT223 (SC-73) package, rated for 500 V VCESM, 1 A continuous collector current, and 150–250 mV VCEsat at IC = 1 A / IB = 200 mA. It serves as a high-efficiency switching element in LED chain drivers and SMPS primary-side control stages where high breakdown voltage and minimal conduction loss are critical.
For engineers reviewing the PBHV8140Z,115 datasheet, PBHV8140Z,115 pinout, PBHV8140Z,115 application, or PBHV8140Z,115 equivalent, key selection criteria include verified VCEsat performance at 1 A, thermal resistance to solder point (15 K/W), dual-collector pin configuration for enhanced heatsinking, and compatibility with FR4 PCB layouts using 6 cm² collector pad per JEDEC-compliant derating curves.
Technical Context
This device implements a planar epitaxial high-voltage NPN structure optimized for low saturation voltage under high-current, high-voltage switching. Its dual-collector pin (Pins 2 & 4) enables direct thermal coupling to large copper areas, supporting 1.45 W Ptot on optimized PCBs while maintaining Tj ≤ 150 °C.
It delivers hFE = 10–20 at IC = 1 A (pulsed), enabling efficient base drive with IB = 200 mA, and exhibits fast switching with ton = 2845 ns and toff = 3800 ns under standardized test conditions (VCC = 6 V, IC = 0.5 A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCESM | 500 V peak - supports surge-tolerant operation in 400 V DC bus applications without clamping |
| VCEsat | 150–250 mV @ IC = 1 A / IB = 200 mA - reduces conduction loss to ≤250 mW in high-duty-cycle switching |
| hFE | 10–20 @ IC = 1 A - enables stable current gain in saturated switch mode with predictable base drive requirements |
| RCEsat | 150–250 mΩ - allows direct calculation of on-state power dissipation under load |
| Rth(j-sp) | 15 K/W - confirms effective thermal path from junction to PCB solder point on standard footprint |
| ICM | 2 A peak - supports short-duration inrush or fault currents without second breakdown |
| fT | 25 MHz - sufficient for <100 kHz SMPS and LED dimming control with margin |
Pinout & Package
SOT223 (SC-73) plastic surface-mount package with 4 leads, 2.3 mm pitch, and integrated heatsink pad (Pin 2 & Pin 4 both connected to collector). Dimensions: 6.5 mm × 3.5 mm × 1.65 mm body; mounting pad area recommended at 6 cm² for full 1.45 W rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input; requires 200 mA pulsed drive for full saturation at 1 A collector current |
| 2 | Collector | Main high-voltage output terminal; electrically tied to Pin 4 for parallel current handling and thermal spreading |
| 3 | Emiter | Reference node for switching; connects to ground or low-side return path in common-emitter topology |
| 4 | Collector | Secondary collector terminal; must be routed to same net as Pin 2 to maintain specified RCEsat and thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| Dual-collector thermal design | Enables 1.45 W total power dissipation via dedicated PCB heatsink pad (6 cm²) and low Rth(j-sp) = 15 K/W |
| Low VCEsat at high current | 250 mV max at IC = 1 A ensures <250 mW conduction loss, improving efficiency in LED driver and SMPS output stages |
| High VCESM rating | 500 V peak withstand supports operation across 380–400 V DC link rails with safety margin against transients |
| Stable hFE up to 1 A | hFE ≥ 10 at full rated current enables predictable base drive sizing without gain collapse |
| Optimized for FR4 PCB | Specified thermal and electrical parameters validated on single-sided tin-plated FR4, eliminating need for exotic substrates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PHB11NQ03LT | MOSFET (30 V VDS, 11 A); lower RDS(on) but insufficient voltage rating for 400 V bus | Only suitable for low-voltage (<60 V) DC-DC stages; cannot replace in LED chain or SMPS primary | Select only if system operates below 40 V and requires zero gate drive current |
| BU406 | TO-126 NPN (400 V VCEO, 5 A); higher VCEsat (~1.5 V), no dual-collector thermal path | Requires heatsink for >0.5 A; incompatible with SMT-only assembly; slower switching (toff > 10 µs) | Choose only for through-hole legacy designs where board space and thermal management allow discrete heatsinking |
Compared with PHB11NQ03LT and BU406, PBHV8140Z,115 uniquely combines 500 V capability, SMT-compatible dual-collector thermal design, and sub-250 mV VCEsat-enabling compact, efficient, and reflow-solderable high-voltage switching without external heatsinks.

FAQ
What is the maximum continuous collector current for PBHV8140Z,115 under standard PCB conditions?
The maximum continuous collector current is 1 A when mounted on an FR4 PCB with standard footprint (Rth(j-a) = 170 K/W), corresponding to 0.73 W total power dissipation at Tamb ≤ 25 °C. Derating applies above 25 °C ambient per Figure 1; at 75 °C ambient, usable IC drops to ~0.5 A.
Can Pins 2 and 4 be used independently in circuit layout?
No-Pins 2 and 4 are internally connected to the same collector region and must be routed to the identical net. Using them separately violates the specified thermal and electrical model, invalidates RCEsat and power derating data, and risks localized overheating due to unbalanced current sharing.
Is PBHV8140Z,115 qualified for automotive applications?
No-per Revision History (Table 8), PBHV8140Z v.3 explicitly states "Product(s) changed to non-automotive qualification." Automotive alternatives are designated with '-Q' suffix (e.g., PBHV8140Z-Q) and undergo additional AEC-Q101 stress testing; this part is intended for industrial, commercial, and consumer equipment only.
What base drive current is required to achieve full saturation at 1 A collector current?
A pulsed base current of 200 mA is required to achieve VCEsat ≤ 250 mV at IC = 1 A (per Table 7, Conditions: IC = 1 A, IB = 200 mA, tp ≤ 300 µs, δ ≤ 0.02). For DC operation, ensure thermal limits permit sustained 200 mA base drive and verify hFE ≥ 5 under actual junction temperature.
