Product details
Overview
P4SMA100A-E3/61 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), 85.5 V maximum standoff voltage (VWM), 137 V clamping voltage (VC) at 2.2 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - suitable for protecting MOSFETs and sensor interfaces in industrial power supplies.
For engineers reviewing the P4SMA100A-E3/61 datasheet, P4SMA100A-E3/61 pinout, P4SMA100A-E3/61 application, or P4SMA100A-E3/61 equivalent, key selection criteria include unidirectional polarity, 1.0 µA max reverse leakage at VWM, -65 °C to +150 °C operating junction temperature, and AEC-Q101 qualification eligibility via HE3/HM3 variants - critical for automotive-grade transient suppression in ECU and ADAS subsystems.
Technical Context
The P4SMA100A-E3/61 operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 95–105 V breakdown range. Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients.
It delivers 400 W peak pulse power (derated to 300 W above 91 V) under 10/1000 µs waveform, with thermal resistance RθJA = 120 °C/W and RθJL = 30 °C/W. The cathode band denotes polarity, and it meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
Key Specifications

IC Role / Device Role / Timing Role: Standoff device across input terminals, conducting only during >85.5 V transients to shunt current to ground. Use Value: Maintains <1 µA leakage at 24 V nominal, ensuring clean logic-level detection while surviving repetitive 2.2 A pulses. |
| Telecom Power Supply Output Stage | Consumer Appliance Motor Driver Board |
|

IC Role / Device Role / Timing Role: Secondary-side TVS connected anode-to-ground, cathode-to-output, clamping fast-rising edges. Use Value: Responds in <1 ns to sub-microsecond transients, limiting overshoot to 137 V and preserving PoE controller integrity. |
Use Scenario: Shields H-bridge gate drivers and current-sense amplifiers from inductive kickback during BLDC motor commutation. IC Role / Device Role / Timing Role: Localized TVS on each half-bridge supply rail (15–20 V), placed adjacent to driver ICs. Use Value: Absorbs 400 W single-event surges without degradation, enabling >100,000-cycle motor runtime reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A | Same SMA package, identical VBR (95–105 V), but lower PPPM = 400 W only up to 85 V; derates earlier above 91 V | Less margin for sustained 100 V+ surges; not AEC-Q101 qualified in standard grade | Select when cost sensitivity outweighs automotive qualification or extended high-voltage surge margin |
| 1.5SMC100A | Higher PPPM = 1500 W, DO-214AB package (larger footprint), higher VC = 165 V at 9.1 A | Requires PCB layout change; better for high-energy lightning strikes but overkill for typical load-switching transients | Choose for legacy designs needing higher surge headroom or where DO-214AB is already standardized |
Compared with SMAJ100A and 1.5SMC100A, the P4SMA100A-E3/61 offers optimal balance of compact SMA footprint, verified 400 W capability at 100 V, and AEC-Q101 upgrade path - making it preferred for space-constrained, automotive-qualified, and industrial-grade 24–48 V system protection.

FAQ
What is the clamping voltage of P4SMA100A-E3/61 and how is it measured?
The clamping voltage (VC) of P4SMA100A-E3/61 is 137 V, measured at a peak pulse current (IPPM) of 2.2 A using the standardized 10/1000 µs double-exponential waveform. This value reflects the maximum voltage seen across the device during a surge event and is guaranteed per Vishay's datasheet revision 09-Jan-2024. The P4SMA100A-E3/61 maintains this clamping performance with <5 % variation across its -65 °C to +150 °C operating junction temperature range.
Is P4SMA100A-E3/61 RoHS-compliant and halogen-free?
Yes, P4SMA100A-E3/61 carries the "E3" suffix, indicating RoHS-compliance per EU Directive 2011/65/EU and exemption 7a, with lead content <1000 ppm. It is not halogen-free; for halogen-free and RoHS-compliant versions, specify P4SMA100A-M3/61 (M3 suffix). Both E3 and M3 variants use matte tin-plated leads and meet JESD 201 Class 2 whisker resistance requirements.
Does P4SMA100A-E3/61 meet AEC-Q101 for automotive use?
The base P4SMA100A-E3/61 is commercial-grade and not AEC-Q101 qualified. However, Vishay offers automotive-qualified variants: P4SMA100AHE3_A (HE3 suffix) and P4SMA100AHM3_A (HM3 suffix), both explicitly rated per AEC-Q101 Rev D for stress testing including HTGB, TCT, and ESD. These require separate ordering codes and are marked with revision "A" per datasheet note (1).
What is the maximum reverse leakage current for P4SMA100A-E3/61 at its standoff voltage?
The maximum reverse leakage current (ID) for P4SMA100A-E3/61 is 1.0 µA at its maximum standoff voltage (VWM) of 85.5 V and ambient temperature of 25 °C. This ultra-low leakage ensures minimal power loss and avoids false triggering in high-impedance sensing circuits. Leakage remains ≤5 µA up to 125 °C per thermal derating curves in Figure 2 of the datasheet.
Can P4SMA100A-E3/61 be used in bidirectional configurations?
No, P4SMA100A-E3/61 is strictly unidirectional, indicated by the "A" suffix and cathode band marking. For bidirectional operation, select the "CA" variant (e.g., P4SMA100CA), which has symmetric breakdown in both directions and no polarity marking. Using P4SMA100A-E3/61 in reverse-biased AC applications risks permanent failure due to forward conduction during negative half-cycles.
