Product details
Overview
P6SMB62CAHM3_A/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 minimum breakdown voltage (VBR at 1 mA), 85.0 V maximum clamping voltage (VC at 7.1 A), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB62CAHM3_A/H datasheet, P6SMB62CAHM3_A/H pinout, P6SMB62CAHM3_A/H application, or P6SMB62CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, low thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMB package supports high surge current handling (IPPM = 7.1 A) without thermal runaway under repetitive 0.01% duty cycle pulses.
The P6SMB62CAHM3_A/H meets J-STD-020 MSL Level 1 moisture sensitivity and is qualified to AEC-Q101 for automotive applications. Its thermal resistance profile (RθJA = 100 °C/W, RθJL = 20 °C/W) enables reliable operation up to TJ = 150 °C when mounted on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients |
| VC (Clamping Voltage) | 85.0 V at 7.1 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines safe stress level for downstream components |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capability under standardized 10/1000 μs waveform |
| IPPM (Peak Pulse Current) | 7.1 A - Maximum non-repetitive surge current the device can safely divert without degradation |
| TJmax | 150 °C - Maximum junction temperature; sets thermal design limits for PCB layout and power cycling |
| Package | SMB (DO-214AA) - Low-profile surface-mount outline with 5.59 mm × 4.06 mm footprint; optimized for automated assembly and thermal pad coupling |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1, compatible with lead-free reflow profiles up to 260 °C peak.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; common terminal in bidirectional configuration | No polarity marking; symmetric conduction means either terminal serves as anode or cathode depending on transient polarity |
| Cathode | Current exit point in forward bias; common terminal in bidirectional configuration | Unmarked - bidirectional devices lack band marking; terminals are functionally interchangeable for transient suppression |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HAST, and mechanical shock testing |
| Halogen-free & RoHS-compliant | Meets JEDEC J-STD-20 and JESD201 Class 2 whisker resistance; suitable for green manufacturing |
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) without failure when properly laid out |
| Low clamping ratio (VC/VBR ≈ 1.30) | Minimizes overvoltage stress on protected ICs compared to higher-ratio TVS devices |
| Fast response time (<1 ns) | Clamps transients before sensitive logic or analog circuits experience damaging overvoltage |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64CA | Same SMB package, 64 V VWM, 71.1 V VBR, 103 V VC at 5.8 A; lower PPPM (400 W); not AEC-Q101 qualified | Limited to commercial-grade industrial and consumer use; unsuitable for automotive under-hood environments | Select when cost sensitivity outweighs automotive qualification and higher clamping voltage is acceptable |
| SMCJ64CA | Higher-power SMC package (DO-214AB), same 64 V VWM, 71.1 V VBR, but 103 V VC at 38.5 A and 1500 W PPPM | Requires larger PCB area; better suited for primary-side AC line protection or high-energy motor drive circuits | Choose when surge energy exceeds 600 W or when board space allows larger footprint for enhanced ruggedness |
Compared with SMAJ64CA and SMCJ64CA, the P6SMB62CAHM3_A/H delivers tighter clamping (85.0 V vs. ≥103 V), automotive qualification, and optimal fit for space-constrained 24 V system nodes where both reliability and precision voltage limiting are critical.

FAQ
What does the "CA" suffix indicate in P6SMB62CAHM3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB62CAHM3_A/H provides symmetrical clamping in both polarities - essential for protecting AC-coupled or differential signal lines like CAN, RS-485, or Ethernet. Unlike unidirectional variants (e.g., P6SMB62A), it has no cathode band marking and conducts identically in either direction above its breakdown threshold.
Is P6SMB62CAHM3_A/H suitable for automotive applications?
Yes, P6SMB62CAHM3_A/H is AEC-Q101 qualified (indicated by the HM3 suffix) and halogen-free, making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. It operates reliably from −65 °C to +150 °C and passes rigorous stress tests required for under-hood deployment.
How does the clamping voltage of P6SMB62CAHM3_A/H compare to its breakdown voltage?
The P6SMB62CAHM3_A/H has a minimum breakdown voltage (VBR) of 58.9 V and a maximum clamping voltage (VC) of 85.0 V at 7.1 A, yielding a clamping ratio of approximately 1.30. This tight ratio ensures minimal overvoltage stress on protected ICs - significantly better than many competing TVS diodes with ratios >1.45.
What is the thermal resistance profile of P6SMB62CAHM3_A/H?
P6SMB62CAHM3_A/H exhibits RθJL = 20 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, measured on 5.0 mm × 5.0 mm copper pads). This dual thermal path enables efficient heat dissipation through solder joints into PCB copper, supporting sustained operation at TJ = 150 °C in compact layouts.
Can P6SMB62CAHM3_A/H replace P6SMB62A in an existing design?
No - P6SMB62CAHM3_A/H is bidirectional while P6SMB62A is unidirectional; they differ in polarity marking, conduction behavior, and circuit placement. Substituting without redesign risks improper clamping during negative transients. Use P6SMB62CAHM3_A/H only where bidirectional protection is explicitly required and validated in the schematic and layout.
