Product details
Overview
P6SMB62AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for robust overvoltage protection of sensitive electronics. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at IT = 1.0 mA), 85.0 V maximum clamping voltage (VC) at 7.1 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P6SMB62AHE3/5B datasheet, P6SMB62AHE3/5B pinout, P6SMB62AHE3/5B application, or P6SMB62AHE3/5B equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package compatibility with automated SMT assembly, low incremental surge resistance, and verified clamping performance under repetitive transients in harsh environments.
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation, it remains high-impedance until transient voltage exceeds VWM = 53.0 V, then avalanches to limit voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown and fast response (<1 ns), while the SMB package provides thermal dissipation via copper pad mounting per JESD22-B102 solderability standards.
The device is rated for TJ = –65 °C to +150 °C operation, supports 100 A non-repetitive forward surge (IFSM, 8.3 ms half-sine), and exhibits a temperature coefficient of VBR = +0.104 %/°C - enabling predictable clamping behavior across automotive and industrial temperature ranges without external compensation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-E3/5B (Vishay) | Same SMB package, but lower PPPM = 400 W; VBR = 66.7–73.7 V; VC = 96.8 V at 4.1 A | Less robust for ISO 16750-2 Pulse 5a; suitable only for 24 V systems with lower surge energy | Select SMAJ60A-E3/5B only if system-level surge testing confirms 400 W sufficiency and layout allows higher VC. |
| 1.5SMC62A (ON Semiconductor) | Same VBR/VC specs and SMB package; 600 W rating; RoHS-compliant but not AEC-Q101 qualified | Lacks automotive qualification - not approved for under-hood or safety-critical modules without additional validation | Choose 1.5SMC62A for cost-sensitive industrial designs where AEC-Q101 is not mandated and traceability is managed internally. |
Compared with SMAJ60A-E3/5B and 1.5SMC62A, P6SMB62AHE3/5B uniquely combines AEC-Q101 qualification, 600 W capability, and 53.0 V VWM in a single-source automotive-qualified part - eliminating need for secondary qualification effort or derating compromises.

FAQ
What is the maximum clamping voltage of P6SMB62AHE3/5B under standard test conditions?
The maximum clamping voltage (VC) of P6SMB62AHE3/5B is 85.0 V, measured at a peak pulse current (IPPM) of 7.1 A using a 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet revision 09-Jan-2024 (Document Number: 88370) and reflects worst-case clamping performance under standardized surge conditions - critical for verifying margin against downstream component absolute maximum ratings in the P6SMB62AHE3/5B protected circuit.
Is P6SMB62AHE3/5B suitable for automotive applications requiring AEC-Q101 qualification?
Yes, P6SMB62AHE3/5B is explicitly AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's P6SMB Series datasheet (Rev. 09-Jan-2024). The HE3 variant undergoes full AEC-Q101 stress testing including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing - making P6SMB62AHE3/5B appropriate for under-hood and safety-related automotive subsystems where qualification evidence is mandatory.
What does the "5B" suffix indicate in P6SMB62AHE3/5B?
The "5B" suffix in P6SMB62AHE3/5B specifies the packaging configuration: 13-inch diameter plastic tape-and-reel with 3200 units per reel. This differs from "52", which denotes a 7-inch reel with 750 units. The "5B" format supports high-volume SMT production lines requiring extended reel life and reduced changeover frequency - a key logistics detail for procurement planning of P6SMB62AHE3/5B in manufacturing environments.
How does the thermal resistance of P6SMB62AHE3/5B affect its power handling in real PCB layouts?
P6SMB62AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads. In practice, this means sustained 5.0 W power dissipation (PD) raises junction temperature by ~500 °C above ambient - confirming that P6SMB62AHE3/5B is intended for transient, not continuous, power handling. Real-world layout must follow Vishay's pad recommendations to maintain specified RθJA and avoid thermal runaway during repetitive surges.
Can P6SMB62AHE3/5B be used in bidirectional configurations?
No, P6SMB62AHE3/5B is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA") and absence of bidirectional marking in its electrical characteristics table. Its cathode band designates polarity, and it conducts only in reverse breakdown. For bidirectional protection, Vishay offers P6SMB62CA variants - using P6SMB62AHE3/5B in bidirectional circuits would result in forward conduction during negative transients and potential failure. Always match device polarity to system requirements when selecting P6SMB62AHE3/5B.
