Product details
Overview
P4SMA480A-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-voltage DC line protection in industrial power supplies and telecom infrastructure. It features a 456 V to 504 V breakdown voltage (VBR), 408 V maximum standoff voltage (VWM), 658 V clamping voltage (VC) at 0.46 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the P4SMA480A-E3/61 datasheet, P4SMA480A-E3/61 pinout, P4SMA480A-E3/61 application, or P4SMA480A-E3/61 equivalent, key selection criteria include high-voltage clamping integrity, SMA (DO-214AC) package compatibility with automated SMT lines, AEC-Q101 qualification status, thermal resistance (RθJA = 120 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
The P4SMA480A-E3/61 operates as a unidirectional avalanche-clamping device, triggered when reverse voltage exceeds its 456–504 V breakdown range at 1.0 mA test current. Its glass-passivated junction ensures stable leakage performance (<1.0 µA at VWM) and fast response time (<1.0 ns) to transient events.
It delivers 400 W peak pulse power under standard 10/1000 µs waveform conditions on 5.0 mm × 5.0 mm copper pads, with derated capability above 25 °C ambient per Fig. 2. The device is rated for -65 °C to +150 °C operating junction temperature and meets J-STD-020 MSL Level 1 reflow profile (260 °C peak).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ480A-E3/52 | Same VBR range (456–504 V), but SMB package (DO-214AA); 600 W PPPM, higher IPPM (0.68 A), RθJA = 90 °C/W | Better power handling and thermal performance, but 25 % larger footprint than SMA | Select when board space allows and higher surge margin is required beyond 400 W |
| 1.5SMC480A | Same electrical specs, but SMC (DO-214AB) package; 1.5 kW PPPM, RθJA = 65 °C/W, 2× larger body than SMA | Designed for high-reliability industrial power systems requiring >1000 surge cycles | Choose for mission-critical 480 V DC systems where extended lifetime under repeated transients is mandatory |
Compared with P4SMA480A-E3/61, SMBJ480A-E3/52 offers superior thermal dissipation and surge margin in a moderately larger package, while 1.5SMC480A provides industrial-grade ruggedness and longevity at the cost of significant PCB area-making P4SMA480A-E3/61 optimal for space-constrained, high-volume telecom and automation designs.

FAQ
What is the breakdown voltage range of the P4SMA480A-E3/61?
The P4SMA480A-E3/61 has a specified breakdown voltage (VBR) range of 456 V to 504 V at a test current of 1.0 mA. This range ensures consistent avalanche initiation across production lots and supports precise coordination with system overvoltage thresholds in 480 V DC applications. The value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay P4SMA datasheet revision 09-Jan-2024.
Is the P4SMA480A-E3/61 AEC-Q101 qualified?
Yes, the P4SMA480A-E3/61 is AEC-Q101 qualified under revision "B" for high-voltage variants (P4SMA250A to P4SMA540A). This qualification covers stress tests including HTGB, HTRB, TCT, and ESD, validating suitability for automotive power electronics such as onboard chargers and battery disconnect units. The "B" suffix is implied in the ordering code structure per Vishay's documentation.
What is the maximum clamping voltage of the P4SMA480A-E3/61 under surge conditions?
The P4SMA480A-E3/61 exhibits a maximum clamping voltage (VC) of 658 V when subjected to its rated peak pulse current of 0.46 A using the 10/1000 µs waveform. This value represents the upper limit of voltage seen by downstream circuitry during a full-power transient event and is critical for ensuring compatibility with 700 V-rated power semiconductors.
Does the P4SMA480A-E3/61 meet UL safety standards?
Yes, the P4SMA480A-E3/61 is Underwriters Laboratories (UL) recognized under file E136766 and standard UL 497B for surge protective devices, with QVGQ2 classification. This approval confirms its suitability for use in telecom and industrial equipment requiring certified overvoltage protection, including installations subject to NEC Article 725 and IEC 62368-1.
What is the thermal resistance of the P4SMA480A-E3/61, and how does it affect layout?
The P4SMA480A-E3/61 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 mandates minimum pad area and copper thickness in PCB layout to avoid thermal runaway during repetitive surge events; reducing pad size increases RθJA and requires corresponding power derating per Fig. 2 in the datasheet.
