Product details
Overview
P6SMB62AHM3_B/I 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 stand-off voltage (VWM), 62.0 V nominal breakdown voltage (VBR min/max: 58.9–65.1 V at 1.0 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 automotive and industrial power supplies.
For engineers reviewing the P6SMB62AHM3_B/I datasheet, P6SMB62AHM3_B/I pinout, P6SMB62AHM3_B/I application, or P6SMB62AHM3_B/I equivalent, this device is selected for robust ESD and surge protection where AEC-Q101 qualification, low incremental surge resistance, and fast response time (<1 ns) are required in space-constrained PCB layouts.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable avalanche behavior under repetitive transient stress. Its thermal resistance (RθJA = 100 °C/W) and junction temperature range (−65 to +150 °C) support operation in automotive under-hood environments when mounted per recommended 0.2" × 0.2" copper pads.
The device delivers 600 W peak pulse power handling with 0.01% duty cycle, validated using standardized 10/1000 μs waveform testing. Its 0.104 %/°C temperature coefficient of VBR ensures predictable voltage drift across operating temperature, critical for precision overvoltage threshold design in DC power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 53.0 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 58.9–65.1 V at 1.0 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating voltage. |
| VC (Clamping) | 85.0 V at 7.1 A - Maximum voltage seen by protected circuit during 10/1000 μs surge; determines downstream component voltage stress. |
| PPPM | 600 W - Peak transient energy absorption capability; enables protection against IEC 61000-4-5 Level 4 surges. |

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, but VWM = 55.0 V, VC = 103 V at 5.8 A; not AEC-Q101 qualified. | Limited to commercial-grade industrial and telecom use; unsuitable 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; RθJA = 60 °C/W vs. 100 °C/W. | Better thermal performance allows higher average power handling; requires larger PCB area and different pad layout. | Choose when board space permits and thermal derating under sustained surge repetition is critical. |
Compared with SMAJ64A-E3/5B and 1.5SMC62A, P6SMB62AHM3_B/I provides AEC-Q101 qualification and tighter clamping (85.0 V vs. 103 V) in a smaller SMB footprint - making it optimal for automotive and space-constrained industrial designs where reliability and voltage margin are prioritized over raw thermal capacity.

FAQ
What is the maximum clamping voltage of P6SMB62AHM3_B/I under standard 10/1000 μs surge conditions?
The maximum clamping voltage (VC) of P6SMB62AHM3_B/I is 85.0 V at 7.1 A peak pulse current, measured with a 10/1000 μs waveform per IEC 61000-4-5. This value defines the upper voltage limit imposed on protected circuitry during transient events and is confirmed in Vishay's official datasheet revision 09-Jan-2024 (Document Number: 88370). The P6SMB62AHM3_B/I maintains this clamping performance across its full operating temperature range.
Is P6SMB62AHM3_B/I qualified for automotive applications?
Yes, P6SMB62AHM3_B/I is AEC-Q101 qualified, as indicated by the "HM3_B" suffix per Vishay's ordering nomenclature. It meets the stress test requirements for automotive-grade transient suppressors, including temperature cycling, humidity bias, and mechanical shock. This qualification makes P6SMB62AHM3_B/I suitable for under-hood and cabin electronics such as body control modules and ADAS sensor power supplies.
What does the "_B/I" suffix in P6SMB62AHM3_B/I signify?
The "_B" denotes AEC-Q101 qualification for the P6SMB62A base series (applicable to 6.8 V–220 V variants), while "/I" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This format aligns with Vishay's standard ordering code structure documented in the P6SMB Series datasheet (page 3, Ordering Information section).
How does the thermal resistance of P6SMB62AHM3_B/I affect its surge handling capability?
P6SMB62AHM3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This value directly impacts its ability to dissipate heat during repetitive surge events: higher RθJA necessitates stricter duty cycle limits (0.01% per datasheet) to avoid junction overheating. For applications requiring higher repetition rates, thermal relief via larger copper areas or heatsinking must be implemented to maintain safe TJ ≤ 150 °C.
Can P6SMB62AHM3_B/I be used in bidirectional configurations?
No, P6SMB62AHM3_B/I is a unidirectional TVS diode, as confirmed by its part number ending in "A" (not "CA") and the presence of a cathode band marking. Bidirectional operation requires CA-suffixed variants like P6SMB62CAHM3_B/I. Using P6SMB62AHM3_B/I in reverse-biased AC signal paths would result in forward conduction and potential failure; always verify polarity alignment in schematic and layout.
