Product details
Overview
P6SMB62AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 53.0 V stand-off 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 - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P6SMB62AHE3_B/H datasheet, P6SMB62AHE3_B/H pinout, P6SMB62AHE3_B/H application, or P6SMB62AHE3_B/H equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, and compliance with J-STD-020 MSL Level 1 (260 °C reflow).
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below 53.0 V and rapidly transitions to low-impedance conduction above its 58.9–65.1 V breakdown threshold, limiting transient-induced voltage excursions to ≤85.0 V at 7.1 A. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and repeatable avalanche behavior under repetitive surges.
Thermal performance is defined by RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), enabling reliable operation up to TJ = +150 °C. The device meets JEDEC JESD201 Class 2 whisker resistance and is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) - critical for load-dump immunity in 12 V automotive systems.
Key Specifications

Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Cathode identified by a single band on the case end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to protected circuit ground or low-side return path; must be routed with minimal inductance for effective clamping. |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
|
Use Scenario: Protecting 12 V supply inputs in engine control units (ECUs) against load dump and alternator transients per ISO 7637-2.

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 | Same SMB package, 60 V VWM, 66.7–73.7 V VBR, 96.8 V VC at 6.2 A; not AEC-Q101 qualified. | Lacks automotive qualification; suitable for commercial/industrial use only; higher VC reduces protection margin for 75 V-rated ICs. | Select when AEC-Q101 is unnecessary and cost sensitivity outweighs clamping voltage optimization. |
| 1.5SMC62A | Same 62 V nominal rating, but in larger SMC (DO-214AB) package; 53 V VWM, 58.9–65.1 V VBR, 85 V VC; AEC-Q101 available in HE3 variant. | Requires PCB layout change due to 2.54 mm longer body and different pad footprint; higher thermal mass improves surge endurance but increases board area. | Choose when higher surge repetition capability or legacy SMC footprint compatibility is prioritized over space-constrained layouts. |
Compared with SMAJ60A, P6SMB62AHE3_B/H offers tighter VC and automotive qualification; versus 1.5SMC62A, it delivers identical electrical specs in a 25% smaller SMB footprint - enabling denser routing in compact ECU and sensor modules.

FAQ
What is the clamping voltage of P6SMB62AHE3_B/H at its rated peak pulse current?
The P6SMB62AHE3_B/H has a maximum clamping voltage (VC) of 85.0 V at 7.1 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuits during surge events - critical for ensuring compatibility with downstream ICs rated for ≤75 V absolute maximum ratings. The P6SMB62AHE3_B/H achieves this with low incremental surge resistance and stable avalanche characteristics.
Is P6SMB62AHE3_B/H qualified for automotive applications?
Yes, P6SMB62AHE3_B/H is AEC-Q101 qualified, as confirmed by the "HE3_B" suffix in its ordering code. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), validating its suitability for under-hood and cabin-mounted automotive electronics such as engine control units, body controllers, and ADAS sensor modules. The P6SMB62AHE3_B/H meets all requirements for automotive-grade TVS deployment per the Vishay P6SMB series specification document 88370.
What does the "_B/H" suffix indicate in P6SMB62AHE3_B/H?
The "_B" in P6SMB62AHE3_B/H denotes AEC-Q101 qualification for the P6SMB6.8A to P6SMB220A voltage range, while "/H" specifies packaging in 7-inch plastic tape-and-reel format with 750 units per reel. This ordering code confirms the part is RoHS-compliant, halogen-free optional (via HM3 variants), and supplied in MSL Level 1 compatible packaging - ready for lead-free reflow assembly. The P6SMB62AHE3_B/H is distinct from non-automotive variants like P6SMB62AE3/52.
How does P6SMB62AHE3_B/H compare to bidirectional TVS diodes in the same series?
P6SMB62AHE3_B/H is unidirectional, meaning it conducts only in reverse breakdown and blocks forward current - ideal for DC power rail protection where polarity is fixed. Bidirectional variants (e.g., P6SMB62CA) have symmetric clamping in both directions and are used on AC lines or data buses like RS-485. The P6SMB62AHE3_B/H offers lower leakage (<1.0 μA at 53 V) and slightly tighter VBR tolerance than its bidirectional counterparts, making it preferred for precision DC protection where forward conduction must be avoided.
What is the thermal resistance of P6SMB62AHE3_B/H, and how does it affect PCB layout?
P6SMB62AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤150 °C under repetitive 600 W surges, PCB layout must provide adequate copper area and minimize trace inductance - especially for the cathode connection. The P6SMB62AHE3_B/H's SMB footprint supports automated placement but requires adherence to Vishay's recommended pad dimensions to ensure thermal and mechanical reliability.
