Product details
Overview
P4SMA10AHE3/5A 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 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 27.6 A peak pulse current, and 400 W peak pulse power capability with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the P4SMA10AHE3/5A datasheet, P4SMA10AHE3/5A pinout, P4SMA10AHE3/5A application, or P4SMA10AHE3/5A equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 120 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
The P4SMA10AHE3/5A operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to suppress transient overvoltages induced by inductive switching or ESD events. Its unidirectional configuration enables integration into DC-biased circuits where reverse conduction must be blocked.
Rated for 150 °C maximum junction temperature and compliant with J-STD-020 MSL Level 1 (260 °C peak reflow), it supports high-reliability automotive applications when ordered with HE3 suffix. The device derates linearly above 25 °C ambient per Figure 2, maintaining 300 W peak pulse power capability above 91 V - though P4SMA10AHE3/5A operates at lower voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 8.55 V - maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown |
| VBR (Breakdown Voltage) | 9.5–10.5 V at 1 mA test current - ensures predictable avalanche onset within tight tolerance band |
| VC (Clamping Voltage) | 14.5 V at 27.6 A IPPM - limits downstream voltage stress during 10/1000 µs transient events |
| PPPM (Peak Pulse Power) | 400 W - sustains short-duration surges without failure when mounted on 5.0 mm × 5.0 mm copper pads |
| ID (Reverse Leakage) | 10 µA max at VWM - minimizes standby power loss in battery-powered or low-power sensor interfaces |
| TJ max | 150 °C - enables operation in under-hood automotive environments and industrial enclosures |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by band marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connects to protected line; conducts surge current to ground when voltage exceeds VBR |
| Anode (unmarked end) | Reference node / ground return | Typically tied to system ground or low-impedance return path to complete clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV) without derating on standard PCB layouts |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive powertrain and body electronics requiring zero-defect reliability and extended temperature operation |
| Glass passivated junction | Improves long-term stability and moisture resistance versus epoxy-passivated alternatives in humid environments |
| MSL Level 1 (260 °C peak) | Supports single-reflow assembly without preconditioning; eliminates moisture-related popcorning risk |
| Low profile SMA package | Reduces board space vs. DO-15 or SMB; compatible with high-density routing and automated optical inspection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VWM (8.55 V), identical SMA package, but rated for 400 W only up to 85 V; no AEC-Q101 qualification | Limited to commercial/industrial use; not approved for automotive under-hood deployment | Select SMAJ10A only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
| 1.5SMC10A | Higher package thermal resistance (RθJA = 150 °C/W vs. 120 °C/W); same electrical specs but larger SMC (DO-214AB) footprint | Requires more PCB area; less suitable for space-constrained modules like ADAS camera boards | Choose 1.5SMC10A only if higher surge energy handling beyond 400 W is required and layout permits larger footprint |
Compared with SMAJ10A and 1.5SMC10A, P4SMA10AHE3/5A uniquely combines AEC-Q101 qualification, optimized thermal performance in compact SMA, and guaranteed 400 W clamping across full temperature range - making it the preferred choice for automotive and high-reliability industrial designs.

FAQ
What is the clamping voltage of P4SMA10AHE3/5A at its rated peak pulse current?
The P4SMA10AHE3/5A has a maximum clamping voltage (VC) of 14.5 V at 27.6 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per datasheet Fig. 1. The clamping performance ensures downstream components see limited overvoltage stress during surge events, and this specification is guaranteed across the full operating temperature range for P4SMA10AHE3/5A.
Is P4SMA10AHE3/5A suitable for automotive applications?
Yes, P4SMA10AHE3/5A is AEC-Q101 qualified, as confirmed by the HE3 suffix and documentation in Vishay's P4SMA series datasheet (Rev. 09-Jan-2024). It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 requirements. This makes P4SMA10AHE3/5A appropriate for under-hood and body electronics where reliability under thermal and mechanical stress is critical.
What is the standoff voltage (VWM) and why does it matter for P4SMA10AHE3/5A?
The standoff voltage (VWM) of P4SMA10AHE3/5A is 8.55 V - the maximum DC or continuous reverse voltage the device can block without entering avalanche conduction. This parameter ensures normal circuit operation (e.g., 5 V or 12 V rails) remains unaffected while still allowing rapid clamping when transients exceed the breakdown threshold. Selecting a VWM correctly relative to system operating voltage prevents false triggering and leakage-related power loss in P4SMA10AHE3/5A deployments.
How does the thermal resistance of P4SMA10AHE3/5A affect its surge handling capability?
P4SMA10AHE3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W. This directly impacts its ability to sustain repetitive surges: higher RθJA means greater junction temperature rise per watt of dissipated energy. For reliable 400 W pulse handling, the device must be mounted on minimum recommended 5.0 mm × 5.0 mm copper pads to achieve specified ratings. Exceeding ambient temperature or reducing pad size degrades P4SMA10AHE3/5A's effective surge capacity per Fig. 2 derating curves.
What packaging format does P4SMA10AHE3/5A ship in, and how does it impact manufacturing?
P4SMA10AHE3/5A ships in 13-inch diameter plastic tape and reel (ordering code /5A), containing 7500 units per reel. This format supports high-speed pick-and-place assembly with standard SMT feeders. The SMA (DO-214AC) package is MSL Level 1 rated for peak reflow of 260 °C, eliminating bake requirements and enabling single-pass reflow - a key advantage for P4SMA10AHE3/5A in high-throughput automotive and industrial manufacturing lines.
