Product details
Overview
P6SMB62AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. 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 (IPPM), and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB62AHM3_A/I datasheet, P6SMB62AHM3_A/I pinout, P6SMB62AHM3_A/I application, or P6SMB62AHM3_A/I equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, thermal derating above 25 °C, unidirectional polarity alignment with DC bias, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR), limiting transient energy by diverting surge current away from downstream components. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while low incremental surge resistance enables effective suppression of high-di/dt events from inductive switching or ESD.
The P6SMB62AHM3_A/I is rated for 150 °C maximum junction temperature, exhibits 0.104 %/°C temperature coefficient of VBR, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for standard lead-free PCB assembly without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 53.0 V - Maximum continuous reverse operating voltage before significant leakage; must exceed normal circuit operating voltage. |
| VBR (Breakdown) | 58.9–65.1 V at 1 mA - Confirmed avalanche onset range; defines minimum overvoltage threshold for clamping activation. |
| VC (Clamping) | 85.0 V at 7.1 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; determines safe margin below downstream device's absolute max rating. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 μs waveform; defines transient energy absorption capacity under repetitive 0.01% duty cycle. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard PCB pad layout; used to calculate temperature rise under steady-state power dissipation. |
| TJ max. | +150 °C - Maximum allowable junction temperature; sets upper limit for thermal design and derating curves above 25 °C ambient. |
| Polarity | Unidirectional - Cathode marked with band; conducts only in reverse-biased avalanche mode, not forward conduction during surges. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current terminal | Connected to lower-potential side of protected line; remains non-conductive under normal operation and reverse transients. |
| Cathode | Avalanche conduction terminal | Marked with band; connected to higher-potential side; initiates clamping when reverse voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges without degradation under specified duty cycle. |
| Glass passivated junction | Ensures stable leakage current (<1 μA at VWM), consistent VBR tolerance, and long-term reliability under thermal cycling. |
| MSL Level 1 rating | Allows direct use in standard reflow processes without baking; eliminates moisture-related popcorning risk during assembly. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD testing - suitable for under-hood and ADAS applications. |
| SMB (DO-214AA) footprint | Standardized 2-pin SMT package compatible with high-speed pick-and-place equipment and IPC-7351B land patterns. |

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 | Same SMB package, 64 V VBR min (60.8–67.2 V), 87.1 V VC at 6.9 A; slightly higher clamping voltage and lower IPPM. | Designed for commercial-grade use; not AEC-Q101 qualified; lacks halogen-free certification. | Select when automotive qualification is unnecessary and cost optimization is prioritized over margin-critical clamping performance. |
| 1.5SMC68A | Higher-power SMC package (7.11 mm × 6.22 mm); 64.6–71.4 V VBR; 113 V VC at 5.3 A; same 600 W PPPM but larger footprint. | Requires PCB redesign due to larger pad layout and higher thermal mass; suited for higher sustained surge duty cycles. | Choose when board space permits and thermal management demands greater junction-to-PCB heat transfer than SMB allows. |
Compared with SMAJ64A-E3/5B, P6SMB62AHM3_A/I offers tighter VBR tolerance and automotive qualification; versus 1.5SMC68A, it delivers identical surge rating in a 30% smaller footprint but with lower thermal mass - making it optimal for space-constrained, high-reliability industrial and automotive PCBs.

FAQ
What is the maximum clamping voltage of the P6SMB62AHM3_A/I under a 10/1000 μs surge?
The P6SMB62AHM3_A/I has a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current of 7.1 A using the standardized 10/1000 μs waveform. This value is measured at the device terminals and represents the highest voltage that will appear across the protected circuit during such a transient event. Engineers must verify that this clamping level remains safely below the absolute maximum voltage rating of downstream components like MOSFETs or ICs.
Is the P6SMB62AHM3_A/I suitable for automotive applications?
Yes, the P6SMB62AHM3_A/I is AEC-Q101 qualified, as indicated by the "HM3" suffix and documented in Vishay's ordering information. It undergoes stress testing for high-temperature operating life, temperature cycling, and ESD robustness required for automotive electronics. The device is explicitly approved for use in engine control units, body control modules, and ADAS sensor interfaces where ambient temperatures reach 125 °C and reliability over 15 years is mandated.
What does the "_A/I" suffix in P6SMB62AHM3_A/I signify?
The "_A/I" suffix in P6SMB62AHM3_A/I denotes packaging configuration: "A" indicates the device belongs to the unidirectional P6SMBxA family (as opposed to bidirectional "CA"), and "I" specifies 13-inch diameter plastic tape-and-reel delivery with 3200 units per reel. This format supports high-volume SMT assembly and aligns with IPC-7351B land pattern requirements for SMB (DO-214AA) packages.
How does the thermal resistance of the P6SMB62AHM3_A/I affect its power handling?
The P6SMB62AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" copper pads. At 25 °C ambient, this limits continuous power dissipation (PD) to 5.0 W before reaching its 150 °C maximum junction temperature. For transient events, thermal mass dominates - but sustained surge repetition requires derating per Figure 2 in the datasheet to avoid cumulative heating beyond safe limits.
Can the P6SMB62AHM3_A/I be used in bidirectional signal line protection?
No, the P6SMB62AHM3_A/I is a unidirectional TVS diode, identified by the "A" (not "CA") suffix and cathode band marking. It conducts only in reverse bias during overvoltage events and blocks forward current. For bidirectional protection - such as on AC-coupled data lines or differential buses - a P6SMB62CA variant must be selected instead, which provides symmetrical clamping in both polarities.
