Product details
Overview
P4SMA62AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, 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 4.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - suitable for protecting MOSFETs and ICs in industrial power supplies.
For engineers reviewing the P4SMA62AHM3_A/H datasheet, P4SMA62AHM3_A/H pinout, P4SMA62AHM3_A/H application, or P4SMA62AHM3_A/H equivalent, key selection considerations include its AEC-Q101 qualification, halogen-free RoHS compliance (HM3 suffix), low incremental surge resistance, and thermal resistance of 120 °C/W junction-to-ambient - critical for automotive-grade transient protection in constrained layouts.
Technical Context
The P4SMA62AHM3_A/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified breakdown range. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), enabling effective suppression of ESD and inductive switching spikes.
Rated for 150 °C maximum junction temperature and compliant with J-STD-020 MSL Level 1, it supports reflow soldering up to 260 °C peak. The device delivers 400 W peak pulse power below 91 V (derated to 300 W above), with clamping performance validated under standardized 10/1000 µs waveform conditions per ANSI/IEEE C62.35.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1 mA - Confirmed avalanche onset range; ensures predictable triggering during transients. |
| VC (Clamping Voltage) | 85.0 V at 4.7 A IPPM - Maximum voltage seen by protected circuit during 10/1000 µs surge; limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standard 10/1000 µs waveform; enables robust protection against IEC 61000-4-5 surges. |
| IPPM (Peak Pulse Current) | 4.7 A - Peak surge current handled at VC; directly determines survivability under defined transient profiles. |
| TJmax | 150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive and high-ambient industrial environments. |
| RθJA | 120 °C/W - Thermal resistance from junction to ambient air; informs derating requirements on standard PCB copper pads (0.2" × 0.2"). |

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-E3/5A | 64 V VWM, 71.1–78.6 V VBR, 103 V VC at 3.9 A; same SMA package but higher clamping voltage and lower PPPM (400 W only up to 43 V). | Less effective clamping margin for 48 V systems; requires higher layout clearance due to elevated VC. | Select when tighter VWM/VBR tolerance (±5% vs ±6.5%) and legacy design compatibility are prioritized over clamping performance. |
| 1.5SMC68A | 68 V VWM, 75.6–83.6 V VBR, 110 V VC at 3.6 A; larger SMC (DO-214AB) package with higher thermal mass but 20% larger footprint. | Not suitable for space-constrained automotive modules; better suited for industrial mains-connected equipment. | Choose for higher surge endurance in non-AEC-Q101 applications where board area permits and 110 V clamping is acceptable. |
Compared with SMAJ64A-E3/5A and 1.5SMC68A, the P4SMA62AHM3_A/H offers superior clamping ratio (VC/VBR ≈ 1.32), AEC-Q101 qualification, and halogen-free compliance - making it the preferred choice for next-generation automotive and compact industrial designs requiring precise 53 V standoff and minimal VC overshoot.

FAQ
What is the maximum clamping voltage of the P4SMA62AHM3_A/H under standard test conditions?
The P4SMA62AHM3_A/H has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and reflects the highest voltage imposed on the protected circuit during a standardized surge event. The P4SMA62AHM3_A/H maintains this clamping performance across its rated operating temperature range and is validated for repetitive surge duty cycles up to 0.01%.
Is the P4SMA62AHM3_A/H qualified for automotive applications?
Yes, the P4SMA62AHM3_A/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P4SMA series datasheet (Rev. 09-Jan-2024). This qualification covers stress tests including temperature cycling, highly accelerated life testing (HALT), and mechanical shock - validating suitability for under-hood and chassis-mounted automotive electronics such as body control modules and ADAS power supplies.
What does the "HM3" suffix indicate in P4SMA62AHM3_A/H?
The "HM3" suffix in P4SMA62AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes the part from commercial-grade E3/M3 variants and confirms compliance with automotive material restrictions (e.g., IEC 61249-2-21). The "_A/H" further specifies packaging in 7" tape-and-reel (H) with revision A, ensuring consistent assembly and traceability for production use of the P4SMA62AHM3_A/H.
How does the P4SMA62AHM3_A/H compare to bidirectional TVS diodes in the same series?
The P4SMA62AHM3_A/H is unidirectional, meaning it protects only against reverse-polarity transients and conducts forward current like a rectifier. Bidirectional variants (e.g., P4SMA62CA) suppress surges in both directions but exhibit higher leakage and reduced VWM margin. For DC power rails where polarity is fixed, the P4SMA62AHM3_A/H provides lower leakage (<1 µA at 53 V) and tighter VBR tolerance - enhancing system efficiency and noise immunity compared to bidirectional equivalents.
What is the thermal resistance and recommended pad layout for the P4SMA62AHM3_A/H?
The P4SMA62AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. This pad size is required to achieve rated 400 W pulse power; smaller pads increase thermal impedance and require derating. The device meets J-STD-020 MSL Level 1, supporting standard reflow without pre-baking.
