Product details
Overview
P4SMA62A-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for clamping voltage transients on power and signal lines. It features a 62 V breakdown voltage (VBR min/max = 58.9 V / 65.1 V at 1 mA), 53.0 V standoff voltage (VWM), 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 industrial power supplies.
For engineers reviewing the P4SMA62A-E3/61 datasheet, P4SMA62A-E3/61 pinout, P4SMA62A-E3/61 application, or P4SMA62A-E3/61 equivalent, key selection criteria include unidirectional polarity, SMA (DO-214AC) package compatibility, 150 °C max junction temperature, low incremental surge resistance, and AEC-Q101 qualification eligibility via HE3/HM3 variants.
Technical Context
The P4SMA62A-E3/61 operates as a unidirectional avalanche diode with glass-passivated junction, enabling fast response to transient overvoltages. Its clamping behavior is defined by a 10/1000 µs waveform test condition, with thermal derating above 25 °C per Fig. 2 and junction-to-ambient thermal resistance of 120 °C/W.
It exhibits 0.104 %/°C temperature coefficient of VBR, 1.0 µA maximum reverse leakage at VWM, and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak. Polarity is marked by a cathode band; no marking applies to bidirectional versions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1 mA - defines reliable avalanche initiation threshold under standardized test conditions |
| VWM | 53.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 85.0 V at 4.7 A - clamped voltage during 400 W transient, limiting stress on downstream components |
| PPPM | 400 W (10/1000 µs) - peak transient energy absorption capability under standard surge waveform |
| IFSM | 40 A (8.3 ms half-sine) - surge current handling for unidirectional forward conduction events |
| TJ max | +150 °C - maximum allowable junction temperature for sustained operation and reliability |
| RθJA | 120 °C/W - thermal resistance from junction to ambient, critical for PCB pad layout and power derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Higher VWM (55.1 V), same VC (85.0 V), SMB package (DO-214AA), 600 W PPPM | Larger footprint; better suited for higher-power board-level protection with greater thermal mass | Select when PCB layout allows larger SMB package and higher surge margin is required beyond 400 W |
| 1.5SMC62A | Same VBR/VWM/VC, SMC (DO-214AB) package, 1500 W PPPM, higher IPPM (24.2 A) | Through-hole or larger SMT footprint; intended for primary-stage surge arrest in AC/DC front ends | Choose for higher-energy threat environments (e.g., AC mains input) where 1.5 kW rating and SMC mechanical robustness are needed |
Compared with SMBJ64A and 1.5SMC62A, the P4SMA62A-E3/61 offers optimal balance of compact SMA footprint, 400 W surge rating, and precise 53.0 V standoff for secondary-side protection in space-constrained industrial and automotive modules.

FAQ
What is the maximum clamping voltage of the P4SMA62A-E3/61 under standard test conditions?
The P4SMA62A-E3/61 has a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current of 4.7 A using the 10/1000 µs waveform. This value is measured per JEDEC standards and ensures predictable overvoltage limiting for protected circuitry downstream of the P4SMA62A-E3/61.
Is the P4SMA62A-E3/61 RoHS-compliant and halogen-free?
Yes, the P4SMA62A-E3/61 carries the "E3" suffix, indicating it is RoHS-compliant and manufactured to commercial-grade specifications. It is not halogen-free; for halogen-free compliance, the "M3" variant (e.g., P4SMA62A-M3/61) must be selected per Vishay's ordering matrix.
Does the P4SMA62A-E3/61 meet AEC-Q101 for automotive use?
The base P4SMA62A-E3/61 is not AEC-Q101 qualified. However, Vishay offers automotive-grade versions under the HE3 and HM3 suffixes (e.g., P4SMA62AHE3_A), which are fully AEC-Q101 qualified and designated for automotive powertrain and body electronics applications.
What is the standoff voltage (VWM) of the P4SMA62A-E3/61, and why does it matter?
The P4SMA62A-E3/61 has a standoff voltage (VWM) of 53.0 V, representing the maximum continuous reverse voltage it can block without entering avalanche conduction. This parameter ensures reliable operation below system operating voltage - for example, protecting a 48 V nominal rail where 53.0 V provides essential margin against ripple and tolerance drift before clamping activates.
Can the P4SMA62A-E3/61 be used in bidirectional configurations?
No - the P4SMA62A-E3/61 is a unidirectional TVS diode, identified by its "A" suffix and cathode band marking. For bidirectional operation, the equivalent part is P4SMA62CA (with "CA" suffix), which provides symmetrical clamping in both polarities and no polarity marking.
