Product details
Overview
P4SMA62AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) in the 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 a 10/1000 µs waveform - suitable for protecting automotive-grade MOSFETs and sensor interfaces against inductive switching surges.
For engineers reviewing the P4SMA62AHE3/61 datasheet, P4SMA62AHE3/61 pinout, P4SMA62AHE3/61 application, or P4SMA62AHE3/61 equivalent, this AEC-Q101 qualified TVS diode delivers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for automotive infotainment power rails, industrial I/O protection, and telecom line interface designs requiring robust ESD and surge immunity.
Technical Context
The P4SMA62AHE3/61 operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and stable breakdown characteristics across -65 °C to +150 °C junction temperature range. Its clamping action begins at VWM = 53.0 V and fully engages at VC = 85.0 V under 4.7 A transient current, limiting energy dissipation to safe levels for downstream ICs.
Designed for surface-mount assembly on 0.2" × 0.2" copper pads, it sustains 40 A non-repetitive forward surge current (8.3 ms half-sine) and maintains thermal resistance of 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), enabling reliable operation without heatsinking in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse operating voltage before significant leakage; defines circuit's normal operating margin before clamping initiates. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 85.0 V at 4.7 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case transient; directly limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Sustained transient energy absorption capability; validated per JEDEC standard waveform for reliability in automotive and industrial environments. |
| IPPM (Peak Pulse Current) | 4.7 A - Maximum transient current the device safely diverts; derived from VC and PPPM, defining surge handling capacity. |
| TJmax | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial settings. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronic systems per stress test requirements including HTOL, TCT, and ESD; enables use in ASIL-B compatible designs. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance. Cathode indicated by band on body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR. |
| Anode (unbanded end) | Reference / return path | Typically tied to system ground or lower-potential rail; completes clamping path during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables protection against ISO 7637-2 Pulse 1/2a/5a surges and IEC 61000-4-5 Line Surge (1 kV/2 Ω) without derating in standard PCB layouts. |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive powertrain and body electronics; eliminates need for additional qualification testing in Tier-1 supply chains. |
| Glass-passivated junction | Ensures stable VBR tolerance (±5 %), low leakage (<1 µA at VWM), and long-term reliability under thermal cycling. |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free reflow profiles without preconditioning; simplifies manufacturing and reduces BOM risk. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD, relay bounce), improving protection margin for 3.3 V/5 V logic interfaces. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A-E3/52 (Vishay) | Higher VWM = 64 V, same SMA package but SMB (DO-214AA) footprint; 600 W PPPM, VC = 103 V at 5.8 A. | Requires PCB layout change (larger pad spacing); suited for higher-voltage rails where 53 V standoff is insufficient. | Select when system VMAX exceeds 58 V and higher clamping margin is acceptable. |
| 1.5SMC62A (ON Semiconductor) | Same VWM/VBR/VC specs, SMC (DO-214AB) package; 1500 W PPPM, but larger footprint and 2× thermal resistance (RθJA = 240 °C/W). | Not drop-in: incompatible pad layout and higher board space; better for high-energy surges where PCB area permits. | Choose only if 1500 W rating is mandatory and layout revision is feasible. |
Compared with SMBJ64A-E3/52 and 1.5SMC62A, the P4SMA62AHE3/61 offers optimal balance of AEC-Q101 compliance, compact SMA footprint, and precise 53 V standoff - making it the preferred choice for space-constrained automotive and industrial PCBs where exact voltage coordination and reflow compatibility are critical.

FAQ
What is the clamping voltage of the P4SMA62AHE3/61 under standard test conditions?
The P4SMA62AHE3/61 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 JEDEC standards and represents the highest voltage the protected circuit will experience during a defined transient event. The P4SMA62AHE3/61 maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C) and is validated for repetitive surge duty cycles up to 0.01 %.
Is the P4SMA62AHE3/61 suitable for automotive applications?
Yes, the P4SMA62AHE3/61 is AEC-Q101 qualified and carries the HE3 suffix indicating automotive-grade construction. It undergoes stress testing for high-temperature operating life, temperature cycling, and ESD robustness required for automotive electronics. The P4SMA62AHE3/61 is commonly deployed in body control modules, infotainment power supplies, and sensor interfaces where ISO 16750-2 compliance and long-term reliability under thermal cycling are essential.
What does the "HE3" suffix mean in P4SMA62AHE3/61?
The "HE3" suffix in P4SMA62AHE3/61 denotes RoHS-compliant, AEC-Q101 qualified construction with matte tin-plated leads and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade E3/M3 versions and confirms qualification for automotive use per stress test requirements including HTOL, TCT, and mechanical shock. The P4SMA62AHE3/61 also meets MSL Level 1 for lead-free reflow processing.
How does the P4SMA62AHE3/61 compare to bidirectional TVS diodes like P4SMA62CA?
The P4SMA62AHE3/61 is unidirectional and intended for DC line protection where polarity is fixed (e.g., VCC-to-GND), offering tighter VBR tolerance and lower leakage than its bidirectional counterpart P4SMA62CA. The P4SMA62AHE3/61 cannot replace P4SMA62CA in AC-coupled or floating signal paths. For applications requiring symmetric clamping on both polarities, P4SMA62CA is required - but the P4SMA62AHE3/61 provides superior performance in single-polarity automotive and industrial power rails.
What is the thermal resistance of the P4SMA62AHE3/61, and how does it affect PCB layout?
The P4SMA62AHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" copper pads per Vishay's recommended layout. This value assumes no external heatsinking and defines allowable power dissipation at ambient temperature. To maintain TJ ≤ 150 °C, average power must stay below ~275 mW at 25 °C ambient. The P4SMA62AHE3/61 does not require thermal vias or large copper pours for typical transient-duty applications, but layout adherence to the specified pad dimensions is critical for rated surge performance.
