Product details
Overview
P4SMA62AHM3/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 - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P4SMA62AHM3/H datasheet, P4SMA62AHM3/H pinout, P4SMA62AHM3/H application, or P4SMA62AHM3/H equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant construction, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
The P4SMA62AHM3/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, lightning-induced surges, and inductive switching transients.
Thermal performance is defined by RθJA = 120 °C/W (junction-to-ambient, free-air) and RθJL = 30 °C/W (junction-to-lead), with derating above 25 °C per Figure 2. It supports repetitive 0.01% duty-cycle pulses and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin below system rail (e.g., 48 V nominal bus) |
| VBR @ IT = 1 mA | 58.9–65.1 V - Verified avalanche conduction threshold; ensures predictable turn-on during overvoltage events |
| VC @ IPPM = 4.7 A | 85.0 V - Clamped voltage seen by protected circuit under 10/1000 µs surge; defines worst-case stress on downstream components |
| PPPM | 400 W - Peak transient energy handling capability; sufficient for IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge testing |
| IFSM | 40 A - Non-repetitive forward surge current rating; supports robustness against accidental polarity reversal or latch-up conditions |

FAQ
What is the maximum clamping voltage of the P4SMA62AHM3/H under a 10/1000 µs surge?
The P4SMA62AHM3/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 Figure 1 and Table on page 2 of Vishay document 88367, and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is the P4SMA62AHM3/H qualified for automotive applications?
Yes, the P4SMA62AHM3/H is AEC-Q101 qualified - confirmed by Vishay's ordering code suffix "HM3", which denotes halogen-free, RoHS-compliant, and automotive-grade qualification. It undergoes stress testing including temperature cycling, HTRB, and ESD per AEC-Q101 Rev D requirements.
What does the "H" suffix in P4SMA62AHM3/H indicate?
The "H" suffix in P4SMA62AHM3/H specifies the tape-and-reel delivery mode: 7-inch diameter plastic tape and reel, with 1800 units per reel. This is defined in Vishay's Ordering Information table (page 3, document 88367) and aligns with industry-standard SMT assembly logistics.
Can the P4SMA62AHM3/H be used in bidirectional configurations?
No, the P4SMA62AHM3/H is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. Bidirectional variants use "CA" suffix (e.g., P4SMA62CA). Using P4SMA62AHM3/H in reverse-biased AC applications would result in forward conduction and failure.
What is the thermal resistance of the P4SMA62AHM3/H in free air?
The P4SMA62AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on minimum recommended pad layout (0.2" × 0.2" copper pads), per Thermal Characteristics table on page 3 of Vishay document 88367. This value assumes no heatsink and natural convection cooling.
