Product details
Overview
P6SMB150AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 150 V standoff voltage (VWM), 158 V maximum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It provides clamping protection for automotive-grade power rails and signal lines in industrial motor drives and telecom interfaces.
For engineers reviewing the P6SMB150AHE3_B/H datasheet, P6SMB150AHE3_B/H pinout, P6SMB150AHE3_B/H application, or P6SMB150AHE3_B/H equivalent, key selection criteria include AEC-Q101 qualification, 207 V maximum clamping voltage at 2.9 A IPPM, low thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT assembly on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, designed to shunt transient energy away from sensitive downstream circuitry during ESD or inductive switching events. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at 128 V) and fast response time (<1.0 ns).
The device complies with J-STD-020 MSL Level 1 (peak reflow ≤260 °C), supports repetitive surge duty cycle of 0.01 %, and delivers consistent clamping behavior across -65 °C to +150 °C operating junction temperature range. Its 100 °C/W junction-to-ambient thermal resistance reflects standard SMB PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 128 V - Maximum continuous reverse voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 143–158 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping) | 207 V at 2.9 A IPPM - Peak voltage seen by protected circuit under 600 W surge; critical for IC survival margin. |
| PPPM | 600 W (10/1000 μs waveform) - Standardized surge energy handling capacity per IEC 61000-4-5. |
| ID (Leakage) | ≤1.0 μA at 128 V - Minimal standby current; avoids loading of high-impedance sensor or bias networks. |
| TJ max. | +150 °C - Enables use in under-hood automotive environments and enclosed industrial enclosures. |
| RθJL | 20 °C/W - Low junction-to-lead thermal resistance supports reliable power dissipation without external heatsinking. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified (HE3_B suffix). Cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink path (unidirectional) | Connected to ground or low-impedance return; completes clamping loop during overvoltage event. |

| 600 W peak pulse rating | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth) without degradation when properly mounted. |
| Glass passivated junction | Ensures stable VBR and low ID over lifetime; eliminates risk of moisture-induced parameter drift. |
| MSL Level 1 rating | Compatible with standard lead-free reflow profiles up to 260 °C peak; no baking required pre-assembly. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a/5a), improving protection fidelity. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs against load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between power input and ground, activated within <1 ns of overvoltage onset.

Use Scenario: Preventing gate oxide damage in high-side N-channel MOSFET drivers exposed to Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Cathode-to-gate, anode-to-source configuration to clamp negative-going gate transients during switching transitions. Use Value: Suppresses sub-10 ns spikes with minimal added capacitance, avoiding driver timing skew or false turn-on. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150A-E3/5B | Same VWM/VBR/VC specs, but SMA package (DO-214AC); RθJA = 125 °C/W vs. 100 °C/W for SMB. | Limited to lower-power or less thermally constrained layouts; not AEC-Q101 qualified. | Select when board space allows larger footprint and automotive qualification is unnecessary. |
| 1.5SMC150AHE3_A | Same electrical specs, but SMC (DO-214AB) package; higher IPPM (3.1 A) due to larger thermal mass; AEC-Q101 qualified. | Better surge endurance in high-repetition scenarios; requires larger PCB pad area (7.1 mm × 6.2 mm vs. 5.0 mm × 5.0 mm). | Choose for mission-critical industrial systems needing extended surge lifetime and proven automotive reliability. |
Compared with SMAJ150A-E3/5B and 1.5SMC150AHE3_A, the P6SMB150AHE3_B/H offers optimal balance of AEC-Q101 compliance, SMB footprint efficiency, and thermal performance for space-constrained automotive and industrial PCBs requiring validated reliability.

FAQ
What is the clamping voltage of P6SMB150AHE3_B/H at its rated peak pulse current?
The P6SMB150AHE3_B/H has a maximum clamping voltage (VC) of 207 V at 2.9 A peak pulse current (IPPM), measured using the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a 600 W transient event and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2.
Is P6SMB150AHE3_B/H qualified for automotive applications?
Yes, P6SMB150AHE3_B/H is AEC-Q101 qualified, as indicated by the "HE3_B" suffix per Vishay's ordering information table (page 3). It meets stress test requirements for temperature cycling, humidity, mechanical shock, and surge robustness required for automotive electronic control units and body electronics.
What is the standoff voltage rating for P6SMB150AHE3_B/H?
The standoff voltage (VWM) for P6SMB150AHE3_B/H is 128 V, representing the maximum DC or continuous reverse voltage the device can withstand without entering breakdown. This value is specified at 25 °C and appears in the Electrical Characteristics table on page 2 of the Vishay P6SMB datasheet.
Does P6SMB150AHE3_B/H have bidirectional capability?
No, P6SMB150AHE3_B/H is a unidirectional TVS diode, as confirmed by its part number suffix "A" (not "CA") and the "UNI" column in the Electrical Characteristics table. Bidirectional variants use the "CA" suffix (e.g., P6SMB150CA) and exhibit symmetric clamping in both polarities.
What is the thermal resistance from junction to lead for P6SMB150AHE3_B/H?
The typical thermal resistance from junction to lead (RθJL) for P6SMB150AHE3_B/H is 20 °C/W, per the Thermal Characteristics table on page 3 of the Vishay datasheet. This low value supports efficient heat transfer to PCB copper pads during repetitive surge events.
