Product details
Overview
P6SMB62CAHE3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 62 V breakdown voltage (VBR min/max = 58.9–65.1 V), 600 W peak pulse power (10/1000 µs), and clamps to ≤85.0 V at 7.1 A peak pulse current - used in automotive sensor interface protection and industrial I/O line surge suppression.
For engineers reviewing the P6SMB62CAHE3_B/I datasheet, P6SMB62CAHE3_B/I pinout, P6SMB62CAHE3_B/I application, or P6SMB62CAHE3_B/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and compliance with IEC 61000-4-2/4-4/4-5 transient immunity requirements.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VWM, and clamping characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior under repetitive surge stress, and low incremental surge resistance enables effective energy diversion during fast transients.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its thermal resistance (RθJA = 100 °C/W) reflects standard SMB pad layout performance, and it supports automated SMT placement without polarity marking due to bidirectional symmetry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 58.9–65.1 V at 1.0 mA test current - defines precise clamping onset threshold for overvoltage events |
| Stand-off Voltage VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| Clamping Voltage VC | ≤85.0 V at 7.1 A peak pulse current (10/1000 µs) - limits downstream voltage stress during surge |
| Peak Pulse Power PPPM | 600 W - sustains standardized lightning/surge waveforms without failure at 0.01% duty cycle |
| Package | SMB (DO-214AA) - industry-standard 2-pin surface-mount outline with 5.59 mm × 4.06 mm footprint |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64CA | Same SMB package, but lower 400 W PPPM; VBR = 71.1–78.6 V; not AEC-Q101 qualified | Limited to commercial-grade industrial or consumer use; insufficient for automotive surge testing | Select when cost sensitivity outweighs automotive qualification and higher surge margin is unnecessary |
| SMCJ64CA | Higher 1500 W PPPM in larger SMC (DO-214AB) package; VBR = 71.1–78.6 V; AEC-Q101 available (HE3 suffix) | Requires larger PCB footprint and different thermal management; suitable for higher-energy threat environments | Choose when system-level surge tests exceed 600 W capability or when design allows SMC package integration |
Compared with SMAJ64CA and SMCJ64CA, P6SMB62CAHE3_B/I delivers optimal balance of AEC-Q101 compliance, 600 W surge handling, and SMB footprint - making it the preferred choice for space-constrained automotive and industrial designs requiring validated reliability without over-engineering.

FAQ
What is the clamping voltage of P6SMB62CAHE3_B/I at its rated peak pulse current?
The P6SMB62CAHE3_B/I clamps to a maximum of 85.0 V at its specified peak pulse current of 7.1 A under the 10/1000 µs waveform condition. This value is measured per JEDEC standards and represents the upper limit of voltage seen by protected circuitry during a full-rated surge event. The actual clamping voltage may be lower depending on test conditions and PCB layout, but 85.0 V is the guaranteed worst-case specification for P6SMB62CAHE3_B/I.
Is P6SMB62CAHE3_B/I suitable for automotive applications?
Yes, P6SMB62CAHE3_B/I is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" and "_B" suffixes in its ordering code. It has undergone stress testing for temperature cycling, high-temperature reverse bias, and ESD robustness per AEC-Q101 Rev D. The device is commonly deployed in engine control units, body control modules, and ADAS sensor interfaces where transient immunity and long-term reliability are mandatory - confirming P6SMB62CAHE3_B/I meets automotive-grade requirements.
How does the bidirectional configuration of P6SMB62CAHE3_B/I affect its circuit implementation?
The bidirectional configuration of P6SMB62CAHE3_B/I eliminates polarity marking and enables direct placement across any two points needing symmetrical overvoltage protection - such as differential signal pairs (RS-485, CAN), AC-coupled lines, or floating sensors. Unlike unidirectional TVS diodes, P6SMB62CAHE3_B/I conducts during both positive and negative transients without requiring external biasing or orientation verification, simplifying layout and reducing assembly errors. Its symmetrical VBR and VC ensure consistent protection regardless of voltage polarity.
What is the maximum operating temperature for P6SMB62CAHE3_B/I?
P6SMB62CAHE3_B/I has a maximum junction temperature (TJ) rating of +150 °C and an operating storage temperature range of −65 °C to +150 °C. This allows deployment in under-hood automotive environments, industrial motor drives, and outdoor telecom enclosures without thermal derating under typical PCB copper pad conditions. The device's RθJA of 100 °C/W assumes standard 0.2" × 0.2" copper pads per terminal - actual thermal performance depends on board layout, but P6SMB62CAHE3_B/I remains fully functional across this full industrial temperature span.
Does P6SMB62CAHE3_B/I require a heatsink for standard operation?
No, P6SMB62CAHE3_B/I does not require an external heatsink for standard transient suppression operation. Its 5.0 W steady-state power dissipation (PD) and thermal resistance (RθJA = 100 °C/W) are designed for operation on standard FR-4 PCBs with minimum recommended copper pads (0.2" × 0.2"). Heatsinking is unnecessary because TVS diodes conduct only briefly during surge events - typically sub-millisecond durations - and self-cool between pulses. Continuous DC power dissipation is negligible in normal operation, so P6SMB62CAHE3_B/I functions reliably without added thermal infrastructure.
