Product details
Overview
P6SMB62AHE3_A/H 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_A/H datasheet, P6SMB62AHE3_A/H pinout, P6SMB62AHE3_A/H application, or P6SMB62AHE3_A/H equivalent, key selection considerations include its AEC-Q101 qualification, SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
The P6SMB62AHE3_A/H operates as a unidirectional avalanche diode, clamping transient overvoltages above its reverse standoff voltage (VWM = 53.0 V) by entering avalanche breakdown. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time (<1.0 ns), critical for protecting MOSFET gates and microcontroller I/O against ESD and inductive switching spikes.
Thermally, it supports continuous operation up to TJ = 150 °C and is rated for 100 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine wave. The device meets J-STD-020 MSL Level 1 and is RoHS-compliant with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.

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-E3/52 (Vishay) | Same SMB package, but lower 600 W rating at 10/1000 μs; VBR = 66.7–73.7 V, VC = 96.8 V at 6.2 A | Higher clamping voltage reduces margin for 5 V systems; suitable where 60 V nominal rail allows wider VC tolerance | Select SMAJ60A-E3/52 only if system-level testing confirms 96.8 V clamping is acceptable for downstream components. |
| 1.5SMC62A (ON Semiconductor) | Same 62 V rating and SMB package; VBR = 58.9–65.1 V, VC = 85.0 V at 7.1 A, but not AEC-Q101 qualified | Lacks automotive qualification; limited to commercial/industrial use where AEC compliance is not mandated | Choose 1.5SMC62A for cost-sensitive non-automotive designs where AEC-Q101 is unnecessary and supply chain diversification is desired. |
Compared with SMAJ60A-E3/52 and 1.5SMC62A, the P6SMB62AHE3_A/H delivers identical electrical clamping performance plus AEC-Q101 validation and tighter VBR distribution - making it the preferred choice for automotive and high-reliability industrial deployments where qualification traceability and thermal stability under extended temperature cycling are mandatory.

FAQ
What is the breakdown voltage tolerance of the P6SMB62AHE3_A/H?
The P6SMB62AHE3_A/H has a breakdown voltage (VBR) range of 58.9 V to 65.1 V at 1.0 mA test current, corresponding to a ±5 % tolerance about the nominal 62 V rating. This tight distribution ensures predictable clamping behavior across production lots and temperature extremes, critical for maintaining safety margins in automotive and industrial power systems where the P6SMB62AHE3_A/H is deployed.
Is the P6SMB62AHE3_A/H suitable for bidirectional transient protection?
No - the P6SMB62AHE3_A/H is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the P6SMB62CA variant. Using the P6SMB62AHE3_A/H in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always verify polarity alignment when integrating the P6SMB62AHE3_A/H into your design.
What does the "HE3_A/H" suffix signify in P6SMB62AHE3_A/H?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification; "A" indicates the revision code per Vishay's internal documentation; "H" specifies packaging in 7" diameter plastic tape and reel (750 units per reel). This full suffix confirms the P6SMB62AHE3_A/H meets automotive-grade reliability standards and arrives in surface-mount assembly-ready format - essential for high-volume automotive and industrial manufacturing using the P6SMB62AHE3_A/H.
How does the thermal performance of P6SMB62AHE3_A/H compare to larger-package TVS devices?
The P6SMB62AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, measured on 0.2" × 0.2" copper pads. While higher than TO-220 or SMC-packaged TVS diodes (e.g., ~50 °C/W), this value is optimized for its SMB footprint. To maintain safe operation at full 600 W pulse rating, PCB layout must follow Vishay's recommended pad dimensions - underscoring why the P6SMB62AHE3_A/H is selected where space constraints outweigh raw thermal capacity.
Can the P6SMB62AHE3_A/H replace older P6KE62A through-hole TVS diodes?
The P6SMB62AHE3_A/H provides equivalent electrical performance (VBR, VC, PPPM) to the through-hole P6KE62A but in an SMB surface-mount package. Direct replacement requires PCB redesign due to different footprint, pad layout, and thermal path. However, the P6SMB62AHE3_A/H enables higher assembly density, automated placement, and improved high-frequency surge response - making it the modern upgrade path where board space and manufacturability are prioritized in new designs using the P6SMB62AHE3_A/H.
