Product details
Overview
BSS87H6327XTSA1 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS small-signal transistor in SOT-89 package, rated for 240 V drain-source breakdown voltage, 0.26 A continuous drain current at 25°C, and 3.9–6 Ω RDS(on) at VGS = 10 V. It serves as a high-voltage, low-current switching element in power management stages of industrial sensor interfaces and LED driver bias circuits.
For engineers reviewing the BSS87H6327XTSA1 datasheet, BSS87H6327XTSA1 pinout, BSS87H6327XTSA1 application, or BSS87H6327XTSA1 equivalent, key selection criteria include dv/dt rating (6 kV/µs), gate threshold voltage range (0.8–1.8 V), reverse diode recovery time (53.6–80.4 ns), and AEC-Q101 qualification for automotive-adjacent reliability.
Technical Context
This device operates as a single N-channel MOSFET with logic-level gate drive compatibility-enabling direct interface with 3.3 V and 5 V microcontrollers without level-shifting. Its 240 V V(BR)DSS and 6 kV/µs dv/dt rating support robust operation in inductive load switching environments where voltage transients exceed standard 100 V devices.
The integrated body diode exhibits 0.82–1.2 V forward voltage at 0.26 A and 53.6–80.4 ns reverse recovery time, making it suitable for freewheeling paths in low-duty-cycle DC-DC flyback snubbers and relay drivers where fast turn-off and low conduction loss are jointly required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 240 V - Withstands up to 240 V drain-source blocking voltage before avalanche conduction begins. |
| RDS(on) @ VGS=10 V | 3.9–6 Ω - On-resistance determines conduction loss in linear or saturated switching applications. |
| ID (continuous) | 0.26 A @ TA=25°C - Maximum steady-state current under free-air conditions with minimal PCB copper. |
| dv/dt rating | 6 kV/µs - Enables reliable operation during rapid voltage transients in inductive switching circuits. |
| VGS(th) | 0.8–1.8 V - Threshold voltage range ensures turn-on with standard logic-level outputs (e.g., STM32 GPIO). |
| Qg | 3.7–5.5 nC - Total gate charge impacts switching speed and driver strength requirements. |
| trr | 53.6–80.4 ns - Reverse recovery time governs diode commutation losses in freewheeling configurations. |
Pinout & Package
Package: SOT-89 (TO-243AA), surface-mount, 3-terminal plastic package with exposed drain pad for thermal dissipation. Pin 2 is drain-connected tab; leads are gull-wing, RoHS-compliant, Pb-free plated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Reference node for gate control; connects to ground or low-side return path. |
| Pin 2 (Drain) | Drain terminal / thermal pad | Main current-carrying output; electrically and thermally connected to exposed metal tab. |
| Pin 3 (Gate) | Control input | High-impedance MOSFET gate; requires <±20 V absolute max and ESD protection per JESD22-A114-HBM Class 1A. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Turns on fully at VGS ≥ 4.5 V, enabling direct MCU GPIO control without external level shifters. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per AEC specification. |
| dv/dt ruggedness | 6 kV/µs rating prevents spurious turn-on during fast voltage transients in relay or solenoid drive circuits. |
| Halogen-free construction | Complies with IEC61249-2-21; eliminates brominated flame retardants for environmental compliance. |
| Low gate charge | Qg ≤ 5.5 nC reduces driver power consumption and enables higher-frequency PWM operation. |
Applications
| Industrial Sensor Power Switching | LED Bias Control |
|---|---|
Use Scenario: Switching 24 V supply to analog sensor front-ends in factory automation PLC modules. IC Role / Device Role / Timing Role: Low-duty-cycle high-voltage switch controlling sensor enable line with fast turn-off to minimize leakage during sleep mode. Use Value: 0.82–1.2 V body diode forward drop minimizes standby power loss; 240 V rating accommodates 24 V systems with margin for surge events. | Use Scenario: Constant-current biasing of high-brightness indicator LEDs in automotive dashboard backlighting.

IC Role / Device Role / Timing Role: Integrated switch-and-freewheeling element eliminating external diode, reducing BOM count and layout area. Use Value: RDS(on) ≤ 6 Ω at 10 V ensures <150 mW conduction loss at 0.26 A; Ciss = 77.5–97 pF enables clean gate drive with 100 Ω series resistor. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BSS84H6327XTSA1 | P-channel counterpart; V(BR)DSS = −50 V, |RDS(on)| = 10 Ω @ VGS = −10 V; not voltage-compatible for high-side 240 V use. | Suitable only for low-voltage high-side switching (≤50 V), not direct replacement in 240 V drain circuits. | Select only when topology requires P-channel configuration and voltage rating permits. |
| DMN2004LK3-7 | N-channel, V(BR)DSS = 20 V, RDS(on) = 3.5 Ω @ 4.5 V; lacks dv/dt rating and AEC-Q101 qualification. | Restricted to ≤20 V systems; unsuitable for 24 V+ industrial transients or automotive-adjacent designs. | Use only in cost-sensitive, low-voltage consumer applications where 240 V capability is unnecessary. |
Compared with BSS84H6327XTSA1 and DMN2004LK3-7, the BSS87H6327XTSA1 uniquely combines 240 V blocking, logic-level gate, AEC-Q101 qualification, and 6 kV/µs dv/dt rating-making it irreplaceable in high-reliability, high-voltage switching roles where alternatives fail on voltage or ruggedness.

FAQ
Is BSS87H6327XTSA1 suitable for 24 V automotive body electronics?
Yes-it is AEC-Q101 qualified and rated for 240 V V(BR)DSS, providing ample margin above 24 V system peaks. Its 6 kV/µs dv/dt rating and −55°C to +150°C operating range meet automotive environmental demands, though it is not intended for engine bay primary power rails.
What is the maximum safe gate-source voltage for continuous operation?
The absolute maximum VGS is ±20 V per datasheet. For reliable long-term operation, gate drive should be limited to −12 V to +12 V, with transient spikes clamped by external Zener diodes if driving inductive loads with high di/dt.
Can this MOSFET replace a discrete 1N4007 + small-signal transistor in a flyback snubber?
Yes-the integrated body diode has 0.82–1.2 V VSD and 53.6–80.4 ns trr, outperforming 1N4007 (trr > 30 µs) in speed and reducing snubber losses. However, its 0.26 A continuous rating limits use to sub-5 W converters.
Does the SOT-89 package require thermal vias for 0.26 A operation?
At 0.26 A and 25°C ambient, the SOT-89 footprint with minimum copper (per datasheet Fig. 1) yields ~125 K/W RthJA. Thermal vias under the drain pad reduce RthJA to ~70 K/W, lowering junction temperature by ~25°C-recommended for sustained operation above 70°C ambient or pulsed loads exceeding 0.21 A.
