Product details
Overview
P4SMA100A-M3/61 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 a 100 V breakdown voltage (VBR = 95–105 V at 1 mA), 137 V maximum clamping voltage (VC) at 2.2 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P4SMA100A-M3/61 datasheet, P4SMA100A-M3/61 pinout, P4SMA100A-M3/61 application, or P4SMA100A-M3/61 equivalent, this device serves as a robust overvoltage protection solution for DC power rails, sensor interfaces, and automotive control modules where fast response (<1 ns), low clamping ratio (1.37×VWM), and halogen-free RoHS compliance are required.
Technical Context
The P4SMA100A-M3/61 operates as a unidirectional avalanche diode with cathode-band polarity marking, leveraging glass-passivated junction technology for stable breakdown and low leakage (<1 µA at 85.5 V). Its thermal resistance (RθJA = 120 °C/W) and junction temperature limit (TJ = 150 °C) support operation under repetitive surge conditions when mounted on 5.0 mm × 5.0 mm copper pads.
It delivers 400 W peak pulse power per 10/1000 µs waveform below 91 V and derates to 300 W above 91 V, with a 0.01% duty cycle rating. The device exhibits a +0.106 %/°C temperature coefficient of VBR, ensuring predictable voltage shift across automotive temperature ranges.
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 |
|---|---|---|---|
| SMBJ100A | Higher package thermal resistance (RθJA = 150 °C/W), same VBR range but 600 W PPPM rating | Preferred for higher-power industrial surge standards (IEC 61000-4-5); less suitable for space-constrained automotive PCBs | Select SMBJ100A only if board layout allows larger SMB footprint and higher surge margin is required beyond 400 W |
| 1.5SMC100A | Same VBR and VC, but DO-214AB package (larger, 7.11 mm × 6.22 mm) and 1500 W PPPM | Used in legacy telecom power supplies requiring higher energy handling; not AEC-Q101 qualified | Choose 1.5SMC100A only for non-automotive, high-reliability AC/DC front-end protection where size is secondary |
Compared with SMBJ100A and 1.5SMC100A, the P4SMA100A-M3/61 offers optimal balance of automotive qualification, compact SMA footprint, and verified 400 W surge capability-making it the preferred choice for new designs targeting AEC-Q101 compliance and PCB area efficiency.

FAQ
What is the maximum clamping voltage of the P4SMA100A-M3/61 under a 10/1000 µs surge?
The P4SMA100A-M3/61 has a maximum clamping voltage (VC) of 137 V at 2.2 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per Figure 1 in Vishay Document 88367 and reflects the actual voltage seen by downstream circuitry during transient events, ensuring protection of 100 V-rated components.
Is the P4SMA100A-M3/61 qualified for automotive applications?
Yes, the P4SMA100A-M3/61 is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure (M3 suffix denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified commercial grade). It is validated for use in automotive environments including engine control, body electronics, and ADAS sensor modules per the January 2024 revision of Document 88367.
What does the "M3" suffix indicate in P4SMA100A-M3/61?
The "M3" suffix in P4SMA100A-M3/61 specifies halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance and MSL Level 1 moisture sensitivity. It distinguishes this variant from E3 (RoHS-compliant only) and HM3 (AEC-Q101 + halogen-free), confirming suitability for green manufacturing and automotive-grade reliability requirements.
How does the thermal resistance of the P4SMA100A-M3/61 affect its surge handling capability?
The P4SMA100A-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 5.0 mm × 5.0 mm copper pads. This value directly limits its ability to dissipate heat during repetitive surges; exceeding the 150 °C junction temperature risks parametric shift or failure, so layout adherence to recommended pad dimensions is critical for rated 400 W performance.
Can the P4SMA100A-M3/61 be used in bidirectional configurations?
No, the P4SMA100A-M3/61 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). Bidirectional operation requires the CA variant (e.g., P4SMA100CA). Using P4SMA100A-M3/61 in reverse-biased signal paths will result in forward conduction and potential damage-its cathode band must face the protected line for correct clamping polarity.
