Product details
Overview
P4SMA62A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on power and signal lines. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at 1 mA), 53.0 V standoff voltage (VWM), 85.0 V maximum clamping voltage at 4.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P4SMA62A-E3/5A datasheet, P4SMA62A-E3/5A pinout, P4SMA62A-E3/5A application, or P4SMA62A-E3/5A equivalent, key selection criteria include unidirectional polarity, SMA (DO-214AC) package compatibility, AEC-Q101 qualification status, clamping performance under repetitive surge conditions, and thermal resistance (RθJA = 120 °C/W) for PCB layout derating.
Technical Context
This TVS diode operates as a voltage-clamping protection device in parallel with sensitive circuit nodes. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable breakdown characteristics across temperature (tempco = 0.104 %/°C). It is rated for non-repetitive 10/1000 µs surges up to 400 W (derated to 300 W above 91 V) and withstands 40 A peak forward surge current (8.3 ms half-sine).
The device is RoHS-compliant (E3 suffix), qualified to AEC-Q101 for automotive use, and meets UL 497B recognition (QVGQ2). Its SMA (DO-214AC) package supports automated placement and achieves MSL Level 1 moisture sensitivity with 260 °C reflow peak temperature tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines precise clamping onset threshold for overvoltage detection |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 85.0 V at 4.7 A - clamped voltage during 10/1000 µs transient, limiting downstream stress |
| PPPM | 400 W (≤91 V), 300 W (>91 V) - peak surge energy absorption capability under standard waveform |
| IFSM | 40 A (8.3 ms half-sine) - surge current handling for short-duration AC line faults or inductive kick |
| RθJA | 120 °C/W - thermal resistance from junction to ambient, critical for power derating on 5.0 mm × 5.0 mm copper pads |
| TJ max | +150 °C - maximum junction temperature, enabling operation in under-hood automotive environments |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to protected line ground or low-side reference | Defines conduction path during transient clamp; must be routed to lowest-impedance return path |
| Cathode | Current exit terminal in forward bias; connected to protected IC/power rail | Band-marked end; connects to vulnerable node - clamping occurs when cathode-to-anode voltage exceeds VBR |
Key Features
| Feature | Design Value |

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 (Littelfuse) | VBR = 71.1–78.6 V, VC = 103 V @ 3.9 A, same SMA package | Higher clamping voltage reduces margin for 60 V-rated circuits; better suited for 64 V nominal systems | Select when system VMAX > 85 V and higher VBR tolerance is acceptable |
| 1.5SMC62A (ON Semiconductor) | VBR = 68.9–76.1 V, VC = 101 V @ 3.9 A, SMC (DO-214AB) package - 1.6 mm taller | Larger footprint and higher RθJA (100 °C/W) require larger copper area for thermal management | Choose only if existing layout accommodates SMC and higher clamping is tolerable |
Compared with SMAJ64A and 1.5SMC62A, P4SMA62A-E3/5A offers tighter VBR tolerance (±5 %), lower clamping voltage (85.0 V), and AEC-Q101 qualification - making it optimal for space-constrained automotive and industrial designs requiring precise voltage limiting and automotive-grade reliability.

FAQ
What is the breakdown voltage range for P4SMA62A-E3/5A?
The P4SMA62A-E3/5A has a specified breakdown voltage (VBR) range of 58.9 V to 65.1 V at a test current of 1.0 mA. This ±5 % tolerance ensures predictable clamping onset across manufacturing lots and temperature extremes, and is verified per the Vishay P4SMA datasheet revision 09-Jan-2024. The value directly determines the minimum overvoltage level at which P4SMA62A-E3/5A begins conducting to protect downstream components.
Is P4SMA62A-E3/5A qualified for automotive applications?
Yes, P4SMA62A-E3/5A is AEC-Q101 qualified, as confirmed in the Vishay P4SMA datasheet (Document Number: 88367, Revision: 09-Jan-2024). The "HE3" variant carries explicit AEC-Q101 qualification, and the E3/5A part shares identical die and construction - validated for temperature cycling, highly accelerated life testing (HALT), and surge robustness required in automotive ECUs and sensor modules. P4SMA62A-E3/5A meets these standards without requiring derating for under-hood deployment.
What is the maximum clamping voltage of P4SMA62A-E3/5A under surge conditions?
The maximum clamping voltage (VC) of P4SMA62A-E3/5A is 85.0 V at a peak pulse current (IPPM) of 4.7 A, measured using the standardized 10/1000 µs double-exponential waveform. This value represents the upper voltage limit imposed on protected circuitry during worst-case transient events, and is critical for ensuring compatibility with 60 V-rated ICs and MOSFETs. The clamping performance is guaranteed across the full operating temperature range for P4SMA62A-E3/5A.
Does P4SMA62A-E3/5A have a bidirectional version?
No, P4SMA62A-E3/5A is strictly unidirectional, indicated by the "A" suffix. Bidirectional variants use the "CA" suffix (e.g., P4SMA62CA). The unidirectional configuration means P4SMA62A-E3/5A conducts only when cathode voltage exceeds anode voltage by ≥VBR; it blocks reverse current like a standard diode. For AC-coupled or symmetrical transient protection, P4SMA62CA must be selected instead - P4SMA62A-E3/5A cannot substitute in those roles.
What is the thermal resistance of P4SMA62A-E3/5A, and how does it affect layout?
P4SMA62A-E3/5A 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. This value requires careful PCB layout: insufficient copper area increases junction temperature during repetitive surges, risking parametric shift or failure. Layouts must allocate minimum pad dimensions per Vishay's recommended mounting footprint, and P4SMA62A-E3/5A derating curves (Fig. 2) must be applied for ambient temperatures above 25 °C.
