Product details
Overview
P6SMB62AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 53.0 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1 mA test current, 85.0 V maximum clamping voltage (VC) at 7.1 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB62AHM3_B/H datasheet, P6SMB62AHM3_B/H pinout, P6SMB62AHM3_B/H application, or P6SMB62AHM3_B/H equivalent, key selection considerations include its AEC-Q101 qualification (HM3 suffix), SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, and thermal resistance of 100 °C/W (junction-to-ambient).
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR), limiting transient energy by diverting surge current away from protected circuitry. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while the low incremental surge resistance enables effective suppression of high-dI/dt events induced by inductive switching or ESD.
The P6SMB62AHM3_B/H is rated for repetitive 10/1000 μs pulses at 0.01 % duty cycle and supports operation from –65 °C to +150 °C junction temperature. Its MSL Level 1 rating (per J-STD-020) and matte tin-plated leads ensure compatibility with standard SMT reflow profiles up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC bias margin. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1 mA - Voltage range where avalanche conduction begins; determines minimum overvoltage trigger point. |
| VC (Clamping Voltage) | 85.0 V at 7.1 A IPPM - Peak voltage seen across device during 10/1000 μs surge; sets worst-case stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Maximum transient energy dissipation capability under standardized 10/1000 μs waveform; defines surge robustness class. |
| RθJA (Thermal Resistance) | 100 °C/W - Junction-to-ambient thermal resistance on recommended 0.2" × 0.2" copper pads; governs derating above 25 °C ambient. |
| TJ max. | +150 °C - Maximum allowable junction temperature; constrains sustained power dissipation and layout thermal design. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability per stress test requirements including HTOL, TCT, and ESD; enabled by HM3 suffix. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads. Cathode identified by a single band at one end; anode is the opposite terminal. Meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased terminal | Connected to protected line; conducts avalanche current during overvoltage events; must be routed to ground or lower-potential rail. |
| Anode (unmarked end) | Reference terminal | Typically tied to system ground or common return path; completes clamping loop during transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables protection against IEC 61000-4-5 Level 3 surges (1 kV/42 Ω) without external series impedance in many 12 V/24 V systems. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive powertrain, body electronics, and ADAS modules requiring extended temperature cycling and lifetime reliability. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving clamping precision. |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow assembly without moisture-related popcorn failure or delamination risk. |
| Glass passivated junction | Ensures stable reverse leakage (<1 μA at VWM) and consistent VBR over time and temperature, critical for long-life industrial deployments. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/5B | Higher VWM (55.1 V), higher VC (103 V at 5.8 A), same SMB package and 600 W rating. | Less precise clamping margin for 53 V systems; better suited for 48 V nominal rails. | Select SMAJ64A-E3/5B only if system VWM tolerance allows ≥55.1 V standoff and layout accommodates higher clamping overshoot. |
| 1.5SMC62A | Same VWM (53.0 V) and VC (85.0 V), but in larger SMC (DO-214AB) package; RθJA = 40 °C/W vs. 100 °C/W. | Superior thermal performance for high-duty-cycle surges; requires larger PCB footprint. | Choose 1.5SMC62A when sustained surge repetition or elevated ambient temperatures demand lower thermal resistance, accepting larger board area. |
Compared with P6SMB62AHM3_B/H, SMAJ64A-E3/5B offers looser clamping control at higher voltages, while 1.5SMC62A delivers identical electrical specs with enhanced thermal handling in a larger package - making P6SMB62AHM3_B/H optimal for space-constrained AEC-Q101-compliant designs needing tight voltage margins.

FAQ
What is the maximum clamping voltage of the P6SMB62AHM3_B/H under a 10/1000 μs surge?
The P6SMB62AHM3_B/H has a maximum clamping voltage (VC) of 85.0 V at 7.1 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB62AHM3_B/H maintains this clamping performance across its specified operating temperature range and is validated for repetitive surges at 0.01 % duty cycle.
Is the P6SMB62AHM3_B/H qualified for automotive applications?
Yes, the P6SMB62AHM3_B/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD robustness, making the P6SMB62AHM3_B/H suitable for use in automotive body electronics, infotainment systems, and ADAS power domains.
What does the "_B/H" suffix indicate in P6SMB62AHM3_B/H?
The "_B" denotes AEC-Q101 qualification for the P6SMB62A variant (applicable to 6.8 V–220 V parts), while "/H" specifies 7" diameter plastic tape-and-reel packaging with 750 units per reel. The full suffix "HM3_B/H" confirms halogen-free, RoHS-compliant construction (HM3), automotive qualification (B), and standard reel format (H). This distinguishes it from commercial-grade (E3/M3) or 13" reel (I) variants.
How does the thermal resistance of the P6SMB62AHM3_B/H affect PCB layout?
The P6SMB62AHM3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repeated surges, PCB layout must provide these minimum pad areas and avoid excessive trace length or isolation. Reducing copper area increases RθJA and risks thermal runaway during high-duty-cycle events - the P6SMB62AHM3_B/H's performance is validated only with this pad configuration.
Can the P6SMB62AHM3_B/H replace a bidirectional TVS in a circuit?
No - the P6SMB62AHM3_B/H is unidirectional, with polarity marked by a cathode band; it conducts only during reverse overvoltage and blocks forward current like a standard diode. Using it in place of a bidirectional device (e.g., P6SMB62CA) would leave the circuit unprotected against positive-going transients on grounded lines. The P6SMB62AHM3_B/H must be oriented with cathode toward the protected line and anode to ground, and cannot substitute for bidirectional suppression without redesigning the protection topology.
