Product details
Overview
P4SMA510A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for high-energy surge protection on power and signal lines. It features a 510 V breakdown voltage (VBR), 434 V standoff voltage (VWM), 698 V clamping voltage (VC) at 0.43 A peak pulse current, and 400 W peak pulse power rating with a 10/1000 µs waveform - suitable for protecting industrial motor drives and telecom power supplies against lightning-induced transients.
For engineers reviewing the P4SMA510A-E3/5A datasheet, P4SMA510A-E3/5A pinout, P4SMA510A-E3/5A application, or P4SMA510A-E3/5A equivalent, key selection criteria include its unidirectional polarity, SMA (DO-214AC) package, 150 °C maximum junction temperature, low leakage (<1 µA at VWM), and AEC-Q101 qualification readiness (via HE3/HM3 variants).
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below its 434 V standoff voltage and rapidly transitions to low-impedance conduction above its 485–535 V breakdown range. Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns) to transient overvoltages.
The device delivers 400 W peak pulse power (derated to 300 W above 91 V) under standardized 10/1000 µs waveform conditions, with thermal resistance of 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), enabling reliable operation on standard 5.0 mm × 5.0 mm copper pads without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 485 V / 535 V at 1.0 mA test current - defines precise avalanche onset window for predictable clamping behavior |
| VWM | 434 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC at IPPM | 698 V at 0.43 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 400 W - peak surge energy absorption capability under standard waveform, derated above 91 V |
| ID at VWM | <1 µA - ultra-low reverse leakage preserves system efficiency in high-impedance bias networks |
| TJ max | 150 °C - enables use in under-hood automotive and industrial environments with elevated ambient temperatures |
| Package | SMA (DO-214AC) - industry-standard SMD outline with 5.28 mm length, 4.50 mm width, and matte tin-plated leads |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, unidirectional configuration with cathode band marking. Dimensions: 5.28 mm × 4.50 mm × 2.29 mm (L × W × H). Molding compound meets UL 94 V-0; terminals solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |

| Glass passivated junction | Ensures stable, repeatable avalanche performance across temperature and lifetime with minimal parameter drift |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free PCB assembly without moisture sensitivity concerns or baking requirements |
| AEC-Q101 qualification option (HE3/HM3) | Validates reliability for automotive applications including engine control modules and ADAS power domains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ510A | Same VBR range (485–535 V), but SMB package (DO-214AA); 600 W PPPM, higher IPPM (0.67 A), larger footprint (4.57 mm × 3.94 mm) | Better suited for higher-energy surges where board space permits larger package; not drop-in compatible due to different pad layout | Select SMBJ510A when surge energy exceeds 400 W or thermal dissipation requires lower RθJA (90 °C/W vs. 120 °C/W) |
| 1.5KE510A | Through-hole DO-201 package; identical electrical specs (VBR, VC, PPPM), but 1.5 kW rating implies higher single-pulse capability (not repetitive) | Used in legacy designs or prototyping where manual assembly or high single-event robustness is prioritized over SMT automation | Choose 1.5KE510A only for through-hole boards or when evaluating worst-case single-surge survivability beyond repetitive 400 W limits |
Compared with SMBJ510A and 1.5KE510A, P4SMA510A-E3/5A offers optimal balance of compact SMA footprint, automated placement compatibility, and verified 400 W repetitive surge handling - making it preferred for space-constrained, high-volume industrial SMT designs requiring consistent long-term clamping stability.

FAQ
What is the breakdown voltage range for P4SMA510A-E3/5A?
The P4SMA510A-E3/5A has a specified breakdown voltage (VBR) range of 485 V to 535 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight 50 V window ensures consistent clamping behavior across production lots and supports precise overvoltage protection design in high-voltage DC systems.
Is P4SMA510A-E3/5A RoHS-compliant and halogen-free?
Yes, P4SMA510A-E3/5A 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., P4SMA510A-M3/5A) must be selected per Vishay's ordering matrix.
Does P4SMA510A-E3/5A have AEC-Q101 qualification?
The base P4SMA510A-E3/5A is not AEC-Q101 qualified. However, Vishay offers automotive-grade versions under HE3 and HM3 suffixes (e.g., P4SMA510AHE3_B), which are fully AEC-Q101 qualified and intended for automotive powertrain and chassis applications.
What is the maximum clamping voltage of P4SMA510A-E3/5A under surge conditions?
The maximum clamping voltage (VC) of P4SMA510A-E3/5A is 698 V at 0.43 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is critical for ensuring downstream components remain within their absolute maximum ratings.
Can P4SMA510A-E3/5A be used in bidirectional configurations?
No - P4SMA510A-E3/5A is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional operation, Vishay specifies part numbers ending in "CA" (e.g., P4SMA510CA), which provide symmetrical clamping in both polarities and omit the polarity band.
