Product details
Overview
P6SMB150AHM3_B/I 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), 207 V clamping voltage (VC) at 2.9 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines in industrial motor drives and automotive power modules against inductive switching transients.
For engineers reviewing the P6SMB150AHM3_B/I datasheet, P6SMB150AHM3_B/I pinout, P6SMB150AHM3_B/I application, or P6SMB150AHM3_B/I equivalent, key selection criteria include verified clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, unidirectional polarity marking, thermal resistance (RθJA = 100 °C/W), and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity identification, designed to shunt transient energy above 150 V standoff while maintaining low leakage (<1.0 μA at VWM). Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1.0 ns) to ESD and lightning-induced surges.
It meets J-STD-020 MSL Level 1 moisture sensitivity and supports reflow up to 260 °C peak. The device is qualified to AEC-Q101 for automotive applications and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications

|---|---|
| VWM (Stand-off) | 150 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR (Breakdown) | 143–158 V at 1.0 mA - Confirmed breakdown threshold range ensuring reliable turn-on margin |
| VC (Clamping) | 207 V at IPPM = 2.9 A - Measured clamping voltage limiting downstream voltage stress during surge |
| PPPM | 600 W - Peak pulse power handling capability with 10/1000 μs waveform, 0.01% duty cycle |
| ID (Leakage) | <1.0 μA at 150 V - Low reverse leakage preserves signal integrity in high-impedance circuits |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient, defining derating requirements on PCB |

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 (150 V), lower PPPM (400 W), non-AEC-Q101, E3 suffix (RoHS, not halogen-free) | Limited to commercial-grade industrial use; lacks automotive qualification and halogen-free certification | Select when cost-sensitive commercial designs require basic 150 V clamping without AEC-Q101 or halogen-free mandates |
| 1.5SMC150AHE3_A/H | Same VWM (150 V), higher RθJA (120 °C/W), identical AEC-Q101 and HM3-equivalent HE3 suffix | Requires larger pad area or forced-air cooling due to higher thermal resistance; same automotive qualification level | Choose only if SMB footprint is unavailable and SMC (DO-214AB) package is acceptable in layout |
Compared with P6SMB150AHM3_B/I, SMAJ150A-E3/5B offers reduced surge robustness and no automotive qualification, while 1.5SMC150AHE3_A/H provides identical electrical specs but demands greater thermal management due to 20% higher junction-to-ambient resistance.

FAQ
What is the clamping voltage of P6SMB150AHM3_B/I at its rated peak pulse current?
The P6SMB150AHM3_B/I has a maximum clamping voltage (VC) of 207 V when subjected to its specified peak pulse current (IPPM) of 2.9 A using a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB150AHM3_B/I maintains this clamping performance across its qualified operating temperature range.
Is P6SMB150AHM3_B/I qualified for automotive applications?
Yes, P6SMB150AHM3_B/I is AEC-Q101 qualified, as confirmed by the "_B" suffix in its ordering code and documented in Vishay's P6SMB series datasheet revision 09-Jan-2024. This qualification covers stress tests including HTGB, H3TRB, and temperature cycling, validating its suitability for automotive powertrain and body electronics. The P6SMB150AHM3_B/I meets all requirements for under-hood deployment up to +150 °C junction temperature.
What does the "HM3" suffix indicate in P6SMB150AHM3_B/I?
The "HM3" suffix in P6SMB150AHM3_B/I denotes halogen-free, RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards. It also confirms compliance with JEDEC JS709E and is distinct from the "HE3" (RoHS only) and "E3/M3" (commercial grade) variants. The P6SMB150AHM3_B/I thus satisfies strict environmental mandates for automotive and industrial OEMs.
How is polarity identified on the P6SMB150AHM3_B/I package?
Polarity on the P6SMB150AHM3_B/I is indicated by a cathode band marked on one end of the SMB (DO-214AA) package body. As a unidirectional TVS, the banded end is the cathode and must be connected toward the protected line (e.g., 150 V rail), while the anode connects to ground or reference. No marking appears on bidirectional variants, but the P6SMB150AHM3_B/I is explicitly unidirectional per its "A" suffix and datasheet designation.
What is the maximum printed circuit board pad size recommended for P6SMB150AHM3_B/I thermal performance?
Vishay specifies that optimal thermal performance for P6SMB150AHM3_B/I requires mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as stated in the "Maximum Ratings" table of document 88370. Deviating from this pad size affects the 100 °C/W RθJA value and alters derating curves in Figure 2. The P6SMB150AHM3_B/I achieves full 600 W pulse power rating only when implemented with this minimum copper area.
