Product details
Overview
P6SMB62AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 53.0 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1 mA, 85.0 V maximum clamping voltage (VC) at 7.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB62AHM3/H datasheet, P6SMB62AHM3/H pinout, P6SMB62AHM3/H application, or P6SMB62AHM3/H equivalent, key selection criteria include its AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, MSL Level 1 rating, 150 °C max junction temperature, and unidirectional polarity with cathode band marking - critical for automotive-grade ESD/surge protection design-in.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by transient overvoltage events, leveraging an avalanche breakdown mechanism to divert surge current away from protected circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the SMB package supports automated SMT placement and meets UL 94 V-0 flammability requirements.
The device is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), exhibits 0.104 %/°C temperature coefficient of VBR, and delivers sub-nanosecond response time to transients - enabling robust protection against inductive switching spikes and lightning-induced surges in DC power rails and I/O lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC operating margin. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1 mA - Avalanche onset range; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | 85.0 V at 7.1 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; determines stress on downstream components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/5B | Same SMB package, 64 V VBR min (60.8–67.2 V), 87.1 V VC at 6.9 A, 400 W PPPM; no AEC-Q101 or halogen-free certification. | Limited to commercial-grade industrial use; not qualified for automotive under-hood deployment. | Select when cost sensitivity outweighs automotive qualification and higher clamping voltage is acceptable. |
| 1.5SMC62A | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package; 1.5 kW PPPM; RoHS-compliant but not AEC-Q101 or halogen-free. | Requires larger PCB area; suited for high-energy surge zones like AC front-ends or motor drives. | Choose for legacy designs needing higher surge margin or where board space permits larger footprint. |
Compared with SMAJ64A-E3/5B and 1.5SMC62A, P6SMB62AHM3/H uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint - making it the only drop-in option for space-constrained, automotive-compliant 12 V/24 V rail protection requiring zero layout revision.

FAQ
What is the maximum clamping voltage of the P6SMB62AHM3/H under a 10/1000 µs surge?
The P6SMB62AHM3/H has a maximum clamping voltage (VC) of 85.0 V when subjected to a 7.1 A peak pulse current with a 10/1000 µs waveform. This value is measured per industry-standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings. The P6SMB62AHM3/H maintains this clamping performance across its full operating temperature range.
Is the P6SMB62AHM3/H qualified for automotive applications?
Yes, the P6SMB62AHM3/H is AEC-Q101 qualified, as indicated by the "HM3" suffix in its part number. This qualification confirms successful completion of stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - validating its suitability for automotive powertrain, chassis, and body electronics. The P6SMB62AHM3/H is specifically intended for under-hood and cabin applications requiring extended temperature operation up to 150 °C.
What does the "HM3" suffix mean in P6SMB62AHM3/H?
The "HM3" suffix in P6SMB62AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. "H" indicates the tape-and-reel packaging format (750 units per 7-inch reel), while "M3" specifies halogen-free molding compound and plating - meeting JESD201 Class 2 whisker resistance and UL 94 V-0 flammability standards. This distinguishes P6SMB62AHM3/H from commercial-grade variants like P6SMB62A-M3/H and confirms its compliance for regulated automotive and green electronics markets.
What is the standoff voltage (VWM) of the P6SMB62AHM3/H?
The standoff voltage (VWM) of the P6SMB62AHM3/H is 53.0 V - the maximum DC or continuous reverse operating voltage that can be applied without initiating significant conduction. This parameter ensures the P6SMB62AHM3/H remains non-conductive during normal operation of 48 V or 24 V systems, providing a safety margin of ≥10 % above typical nominal rail voltages while allowing headroom for ripple and tolerance drift.
How does the P6SMB62AHM3/H compare to bidirectional TVS diodes in the same series?
The P6SMB62AHM3/H is unidirectional, meaning it conducts only in reverse bias (cathode positive) and blocks forward current - ideal for DC power rail protection where polarity is fixed. Bidirectional variants (e.g., P6SMB62CA) offer symmetrical clamping for AC or floating signal lines but exhibit higher leakage and slightly reduced surge capability. The P6SMB62AHM3/H's unidirectional architecture delivers lower leakage (<1.0 µA at VWM) and tighter VBR tolerance, making it preferred for precision DC protection where forward conduction must be avoided.
