Product details
Overview
P6SMB62CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 53.0 V standoff voltage (VWM), 65.1 V maximum breakdown voltage (VBR), 85.0 V clamping voltage (VC) at 7.1 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB62CAHE3_B/H datasheet, P6SMB62CAHE3_B/H pinout, P6SMB62CAHE3_B/H application, or P6SMB62CAHE3_B/H equivalent, this device is evaluated for bidirectional surge protection in DC power rails, automotive control modules, and I/O line transient suppression where AEC-Q101 qualification, low clamping ratio, and MSL Level 1 reliability are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping performance without polarity dependence. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), while the 20 °C/W junction-to-lead thermal resistance supports reliable energy dissipation under repetitive surge conditions.
The device meets AEC-Q101 qualification (automotive grade) and is RoHS-compliant with matte tin-plated leads solderable per J-STD-002. Its SMB package enables automated placement and provides UL 94 V-0 flammability rating, with thermal derating defined up to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC working margin. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1.0 mA - Voltage range at which avalanche conduction initiates; tight tolerance ensures predictable turn-on. |
| VC (Clamping Voltage) | 85.0 V at 7.1 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Maximum transient energy absorption capability with standard 10/1000 μs waveform; validates robustness against lightning/inductive spikes. |
| ID (Reverse Leakage) | <1.0 μA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | +150 °C - Maximum junction temperature rating enabling operation in under-hood automotive and industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | 64 V VWM, 71.1 V VBR, 103 V VC at 5.8 A; same SMB package but lower PPPM (600 W) and higher clamping voltage. | Higher clamping voltage increases stress on protected ICs; less suitable for 3.3 V/5 V logic interfaces near threshold. | Select when system-level testing confirms 103 V clamping is acceptable and tighter VBR tolerance is not required. |
| 1.5SMC68CA | 68 V VWM, 75.6 V VBR, 110 V VC at 5.5 A; larger SMC (DO-214AB) package with higher thermal mass but 20 % larger footprint. | Requires PCB redesign due to 7.11 mm × 6.22 mm SMC outline; better for high-repetition-rate surges but over-specified for space-constrained boards. | Choose only if thermal cycling endurance >10⁶ cycles is mandatory and board area permits larger package. |
Compared with SMBJ64CA and 1.5SMC68CA, P6SMB62CAHE3_B/H delivers the lowest clamping voltage (85.0 V) in SMB form factor with AEC-Q101 validation - making it optimal for automotive and high-density industrial designs where voltage margin and qualification compliance are critical.

FAQ
What is the clamping voltage of P6SMB62CAHE3_B/H at its rated peak pulse current?
The P6SMB62CAHE3_B/H has a maximum clamping voltage (VC) of 85.0 V at 7.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events. The low clamping ratio (VC/VWM ≈ 1.60) makes P6SMB62CAHE3_B/H especially effective for safeguarding 5 V and 3.3 V logic interfaces.
Is P6SMB62CAHE3_B/H suitable for automotive applications?
Yes, P6SMB62CAHE3_B/H is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" and "_B" suffixes in its ordering code. It undergoes rigorous stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST). Its 150 °C maximum junction temperature and MSL Level 1 rating make P6SMB62CAHE3_B/H appropriate for under-hood and cabin ECU designs per ISO 16750-2 requirements.
How does the bidirectional configuration of P6SMB62CAHE3_B/H affect circuit layout?
The bidirectional nature of P6SMB62CAHE3_B/H eliminates polarity marking and orientation constraints - either terminal functions identically regardless of voltage polarity. This simplifies PCB layout by removing the need for silkscreen indicators or asymmetric pad design. Engineers place P6SMB62CAHE3_B/H directly across differential lines (e.g., CAN_H/CAN_L) or ungrounded rails without concern for anode/cathode assignment, reducing assembly errors and enabling symmetrical routing.
What is the thermal resistance specification for P6SMB62CAHE3_B/H?
P6SMB62CAHE3_B/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and a junction-to-ambient resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. These values enable accurate thermal modeling of power dissipation during repetitive surge events. For sustained 5.0 W steady-state operation, P6SMB62CAHE3_B/H requires adequate copper area or supplemental heatsinking to maintain TJ ≤ 150 °C.
Does P6SMB62CAHE3_B/H meet RoHS and halogen-free requirements?
Yes, P6SMB62CAHE3_B/H is RoHS-compliant and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The "HE3" suffix indicates RoHS compliance and AEC-Q101 qualification; it is not halogen-free (which would require "HM3" suffix). Material declarations confirm full compliance with EU RoHS Directive 2011/65/EU and exemption 7a, with no intentionally added REACH SVHC substances above threshold limits.
