Product details
Overview
P6SMB62AHM3/I 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, 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 - deployed in automotive-grade protection circuits for engine control units and sensor interfaces.
For engineers reviewing the P6SMB62AHM3/I datasheet, P6SMB62AHM3/I pinout, P6SMB62AHM3/I application, or P6SMB62AHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant HM3 suffix, SMB (DO-214AA) package compatibility, and verified clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This device operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a well-controlled VC/IPPM relationship under standardized 10/1000 μs transients, with thermal derating governed by RθJA = 100 °C/W and RθJL = 20 °C/W.
The P6SMB62AHM3/I is rated for -65 °C to +150 °C operating junction temperature, supports 100 A non-repetitive forward surge current (IFSM), and meets J-STD-020 MSL Level 1 with 260 °C lead-free reflow peak. Its cathode-band polarity marking aligns with standard SMB layout conventions for automated placement.

IC Role / Device Role / Timing Role: Standoff-rated TVS connected across input optocoupler terminals; absorbs ±1 kV/500 A transients per IEC 61000-4-5. Use Value: Eliminates false triggering and extends optocoupler lifetime by limiting reverse voltage across LED anode-cathode to <85 V during surge events. |
| Automotive Cabin Sensor Interface Protection | Telecom Power Supply DC-DC Stage Clamp |
Use Scenario: Safeguards LIN bus transceivers and MEMS sensor power pins in HVAC and seat control modules exposed to board-level ESD and cable discharge. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on 5 V sensor supply; positioned upstream of LDO to prevent dropout during ESD bursts.

Use Scenario: Clamps secondary-side rectifier output in telecom AC/DC adapters subjected to lightning-induced surges on AC mains input. IC Role / Device Role / Timing Role: Secondary-side TVS across bulk capacitor; activated only during overvoltage fault conditions to protect synchronous rectifier MOSFETs. Use Value: Prevents catastrophic failure of 100 V GaN FETs by limiting reflected surge voltage to <85 V, maintaining safe operating area during 6 kV ring-wave tests. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/5B | Same SMB package, 64 V VWM, 71.1 V VBR, 103 V VC at 5.8 A; commercial-grade (not AEC-Q101 qualified); higher clamping voltage. | Lacks automotive qualification; suitable for industrial/commercial power supplies where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive compliance and higher clamping voltage is acceptable in system margin analysis. |
| 1.5SMC62AHE3/A | Same 62 V rating, SMC (DO-214AB) package (larger footprint), 1500 W PPPM; AEC-Q101 qualified; requires PCB layout change. | Higher power handling but incompatible pin-to-pin replacement due to larger 7.11 mm × 6.22 mm body vs. SMB's 3.94 mm × 2.20 mm. | Choose only if system-level surge testing exceeds 600 W and board space allows SMC footprint; not a drop-in substitute. |
Compared with P6SMB62AHM3/I, SMAJ64A-E3/5B offers lower cost but no automotive qualification or tight clamping, while 1.5SMC62AHE3/A delivers higher surge capacity at the expense of PCB real estate and layout redesign - making P6SMB62AHM3/I the optimal balance of AEC-Q101 compliance, SMB footprint, and 85 V clamping for space-constrained automotive modules.

FAQ
What is the clamping voltage of P6SMB62AHM3/I at its rated peak pulse current?
The P6SMB62AHM3/I has a maximum clamping voltage (VC) of 85.0 V at 7.1 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB62AHM3/I maintains this clamping performance across its specified operating temperature range and is validated for repetitive surge duty cycles up to 0.01%.
Is P6SMB62AHM3/I qualified for automotive applications?
Yes, P6SMB62AHM3/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P6SMB series datasheet (Document Number: 88370, Revision: 09-Jan-2024). The HM3 designation indicates halogen-free, RoHS-compliant construction with full automotive stress testing including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. This makes P6SMB62AHM3/I suitable for engine control, body electronics, and ADAS subsystems.
What package type does P6SMB62AHM3/I use, and what are its key mechanical dimensions?
P6SMB62AHM3/I uses the SMB (DO-214AA) surface-mount package, measuring 3.94 mm × 2.20 mm × 1.52 mm (length × width × height) with a 0.205" × 0.220" PCB footprint. Its cathode is marked by a visible band, and terminals are matte tin-plated for solderability per J-STD-002 and JESD 22-B102. The package meets UL 94 V-0 flammability rating and is rated MSL Level 1 for unlimited floor life.
How does the P6SMB62AHM3/I differ from the P6SMB62AHE3/I variant?
The P6SMB62AHM3/I differs from P6SMB62AHE3/I primarily in material composition: HM3 denotes halogen-free and RoHS-compliant construction, while HE3 is RoHS-compliant but not halogen-free. Both are AEC-Q101 qualified and share identical electrical specifications, SMB packaging, and thermal characteristics. The HM3 version satisfies stricter environmental mandates such as JEDEC JS709E, making it preferred for global automotive programs with halogen restrictions.
What is the maximum operating junction temperature for P6SMB62AHM3/I?
The maximum operating junction temperature (TJ max.) for P6SMB62AHM3/I is +150 °C, as specified in the Absolute Maximum Ratings table of the Vishay P6SMB datasheet. This rating enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures. Thermal design must account for RθJA = 100 °C/W and RθJL = 20 °C/W to ensure junction temperature remains within limits under worst-case power dissipation.
