Product details
Overview
P4SMA62CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 62 V breakdown voltage (VBR = 58.9–65.1 V at 1 mA), 85 V maximum clamping voltage (VC) at 4.7 A peak pulse current, and 400 W peak pulse power (10/1000 µs waveform). It protects signal lines and power rails in automotive sensor interfaces and industrial I/O modules against ESD and inductive switching transients.
For engineers reviewing the P4SMA62CAHM3_A/I datasheet, P4SMA62CAHM3_A/I pinout, P4SMA62CAHM3_A/I application, or P4SMA62CAHM3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, halogen-free RoHS compliance, low thermal resistance (RθJL = 30 °C/W), and compatibility with automated SMT placement on standard 5.0 mm × 5.0 mm copper pads.
Technical Context
The P4SMA62CAHM3_A/I operates as a voltage-clamped transient protector with symmetrical avalanche behavior in both directions, enabling robust protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns) to sub-microsecond transients.
Designed for surface-mount reliability, it meets MSL Level 1 per J-STD-020 (peak reflow ≤260 °C), supports repetitive surge duty cycles up to 0.01%, and delivers 3.3 W steady-state power dissipation at TA = 50 °C on infinite heatsink - validated using standardized 0.2" × 0.2" copper pad layout per Fig. 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1 mA - defines precise clamping onset threshold for overvoltage events |
| VWM | 53.0 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 85.0 V at 4.7 A (10/1000 µs) - actual clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 400 W - peak transient energy absorption capability under standardized surge waveform |
| IPPM | 4.7 A - maximum non-repetitive surge current the device safely conducts without degradation |
| RθJL | 30 °C/W - low junction-to-lead thermal resistance enables efficient heat transfer to PCB traces |
| TJ max | +150 °C - maximum operating junction temperature supporting automotive under-hood environments |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, halogen-free, RoHS-compliant, AEC-Q101 qualified. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H); cathode band not marked (bidirectional type).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (positive polarity) | One terminal of symmetrical avalanche junction; accepts surge current in either direction |
| Cathode | Transient current exit (negative polarity) | Second terminal of symmetrical avalanche junction; completes bidirectional conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both polarities - eliminates need for polarity-aware layout in AC/differential circuits |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, ADAS sensors, and infotainment I/O |
| Halogen-free & RoHS | Meets JEDEC J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance - compliant with global environmental and safety standards |
| Low RθJL | 30 °C/W junction-to-lead thermal resistance - enables effective self-cooling via PCB copper without external heatsinking |
| 400 W peak pulse rating | Rated for 10/1000 µs waveform at TA = 25 °C - handles high-energy transients from relay coils, solenoids, and motor drives |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF at VWM) TVS minimizes signal distortion on touch and display signal lines. Use Value: Passes IEC 61000-4-2 Level 4 (±8 kV contact) without affecting button responsiveness or LCD timing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Higher VBR (60.8–67.2 V), same SMA package but SMB (DO-214AA) footprint - larger body (4.57 mm × 3.94 mm) | Lower power density (600 W vs. 400 W) but higher IPPM (64.9 A); requires PCB layout change | Select when higher surge margin is needed and board space allows SMB footprint |
| SMCJ64CA | Same VBR range, SMC (DO-214AB) package - 7.11 mm × 6.22 mm, RθJL = 15 °C/W | Higher PPPM (1500 W), better thermal performance, but incompatible with SMA land pattern | Choose for high-reliability industrial power supply inputs where layout revision is acceptable |
Compared with SMBJ64CA and SMCJ64CA, the P4SMA62CAHM3_A/I offers optimal balance of AEC-Q101 qualification, halogen-free compliance, and compact SMA footprint - making it the preferred choice for space-constrained automotive and consumer electronics where drop-in replacement on existing DO-214AC layouts is required.

FAQ
What is the breakdown voltage tolerance of the P4SMA62CAHM3_A/I?
The P4SMA62CAHM3_A/I has a specified breakdown voltage range of 58.9 V to 65.1 V at test current IT = 1 mA, representing ±5% tolerance around the nominal 62 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes from −65 °C to +150 °C.
Is the P4SMA62CAHM3_A/I suitable for automotive applications?
Yes, the P4SMA62CAHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction with automotive-grade reliability validation. It is explicitly rated for use in engine control units, ADAS sensor interfaces, and body electronics where transient immunity and long-term stability are critical.
How does the P4SMA62CAHM3_A/I differ from unidirectional variants like P4SMA62A?
The P4SMA62CAHM3_A/I is bidirectional, meaning its electrical characteristics - including VBR, VC, and IPPM - apply identically in both polarities, with no cathode marking. In contrast, P4SMA62A is unidirectional, features a cathode band, and only clamps in reverse bias - making P4SMA62CAHM3_A/I ideal for AC, differential, or polarity-agnostic protection schemes.
What is the maximum clamping voltage of the P4SMA62CAHM3_A/I under surge conditions?
The P4SMA62CAHM3_A/I exhibits a maximum clamping voltage (VC) of 85.0 V at peak pulse current IPPM = 4.7 A under the standardized 10/1000 µs waveform. This value is measured after the device enters avalanche conduction and represents the highest voltage imposed on the protected circuit during worst-case transient events.
Does the P4SMA62CAHM3_A/I require special PCB layout considerations?
Yes - for optimal thermal and surge performance, the P4SMA62CAHM3_A/I must be mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as defined in Vishay's datasheet Figure 3. Smaller pads increase thermal resistance and reduce surge current handling, potentially leading to premature failure during repetitive transients.
