Product details
Overview
P6SMB150AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 150 V standoff voltage (VWM), 158 V maximum breakdown voltage (VBR), 207 V clamping voltage at 2.9 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform.
For engineers reviewing the P6SMB150AHE3/5B datasheet, P6SMB150AHE3/5B pinout, P6SMB150AHE3/5B application, or P6SMB150AHE3/5B equivalent, key selection criteria include clamping performance under 10/1000 μs surge, unidirectional polarity for DC rail protection, AEC-Q101 qualification status, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (143–158 V), it avalanches rapidly to limit transient energy across protected lines. Its glass-passivated junction ensures stable leakage (<1.0 μA at 128 V) and low incremental surge resistance, enabling consistent clamping at VC = 207 V under IPPM = 2.9 A.
Designed for high-reliability environments, P6SMB150AHE3/5B meets MSL level 1 per J-STD-020, supports peak reflow temperatures up to 260 °C, and is AEC-Q101 qualified - confirming suitability for automotive powertrain and body electronics where transient immunity and long-term stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 128 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC bias margin. |
| VBR (Breakdown) | 143–158 V at 1 mA - Voltage range at which avalanche conduction initiates; tight tolerance enables predictable turn-on. |
| VC (Clamping) | 207 V at IPPM = 2.9 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| ID (Leakage) | <1.0 μA at 128 V - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial enclosures. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" footprint; compatible with IPC-7351B land patterns. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side of protected line; defines unidirectional conduction path. |
| Cathode | Avalanche conduction terminal / Clamping node | Connected to higher-potential rail (e.g., +12 V, +24 V); carries full surge current during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS power supplies - ensures reliability over temperature and lifetime. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 10/1000 μs surge waveforms up to Level 4 (4 kV open-circuit), protecting against real-world lightning-induced transients. |
| Glass-passivated junction | Provides stable electrical characteristics over time and temperature; eliminates parameter drift due to moisture or contamination. |
| MSL Level 1 rating | Enables single-reflow assembly without moisture sensitivity concerns; supports standard SMT processes up to 260 °C peak temperature. |
| Low clamping ratio (VC/VBR ≈ 1.31) | Minimizes overvoltage stress on protected MOSFETs or microcontrollers - critical for 150 V-rated systems like commercial vehicle battery management. |
Applications

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 SMB package, identical VWM/VBR/VC specs, but rated for 400 W PPPM (vs. 600 W) and not AEC-Q101 qualified. | Lacks automotive qualification; suitable for commercial/industrial use only where surge severity is lower. | Select when cost sensitivity outweighs need for 600 W rating or automotive compliance. |
| 1.5SMC150AHE3/A | Same electrical specs and AEC-Q101 qualification, but in larger SMC (DO-214AB) package with higher thermal mass and RθJA = 30 °C/W (vs. 100 °C/W). | Better thermal dissipation for repetitive surge duty cycles; requires larger PCB area and different land pattern. | Choose for high-duty-cycle applications or where board space permits larger footprint and improved thermal margin. |
Compared with SMAJ150A-E3/5B and 1.5SMC150AHE3/A, P6SMB150AHE3/5B uniquely balances 600 W surge capability, AEC-Q101 qualification, and compact SMB footprint - making it optimal for space-constrained automotive modules requiring validated reliability and high single-pulse immunity.

FAQ
What is the clamping voltage of P6SMB150AHE3/5B at its rated peak pulse current?
The clamping voltage (VC) of P6SMB150AHE3/5B is 207 V at a peak pulse current (IPPM) of 2.9 A with a 10/1000 μs waveform. This value is measured under standardized test conditions and defines the maximum voltage imposed on protected circuitry during a surge event. The P6SMB150AHE3/5B maintains this clamping performance consistently due to its glass-passivated junction and low incremental surge resistance.
Is P6SMB150AHE3/5B qualified for automotive applications?
Yes, P6SMB150AHE3/5B is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's P6SMB series datasheet (Rev. 09-Jan-2024). This qualification validates its reliability for automotive powertrain, body electronics, and ADAS systems under extended temperature cycling, humidity, and mechanical stress. The P6SMB150AHE3/5B meets all required tests including HTOL, TCT, and ESD.
What does the "HE3/5B" suffix indicate in P6SMB150AHE3/5B?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification, while "5B" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This format supports high-volume automated SMT placement. The P6SMB150AHE3/5B is distinct from non-automotive variants (e.g., E3/52) and non-qualified versions (e.g., E3/5B without H), ensuring traceability and compliance alignment.
How does P6SMB150AHE3/5B compare to bidirectional TVS diodes in the same series?
P6SMB150AHE3/5B is unidirectional, meaning it conducts only in reverse bias above VBR and blocks forward current - ideal for DC power rail protection. Bidirectional variants (e.g., P6SMB150CA) conduct symmetrically in both directions and are used for AC or data-line protection. The P6SMB150AHE3/5B offers tighter leakage control (<1.0 μA) and avoids ambiguity in polarity-sensitive designs, unlike bidirectional types which lack cathode marking.
What is the thermal resistance of P6SMB150AHE3/5B, and how does it affect layout design?
P6SMB150AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal PCB copper; designers must allocate adequate thermal pad area and consider airflow or adjacent heat sources. For sustained surge duty, adding thermal vias or increasing pad size improves derating - critical because the P6SMB150AHE3/5B operates up to +150 °C junction temperature.
