Overview
P4SMA10A-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for clamping inductive switching transients and ESD events on power and signal lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 27.6 A peak pulse current, and 400 W peak pulse power rating with a 10/1000 µs waveform. It is used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive control modules.
For engineers reviewing the P4SMA10A-E3/61 datasheet, P4SMA10A-E3/61 pinout, P4SMA10A-E3/61 application, or P4SMA10A-E3/61 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal derating curves, and RoHS-compliant commercial-grade sourcing details - all specific to the P4SMA10A-E3/61 variant.
Technical Context
The P4SMA10A-E3/61 operates as a unidirectional avalanche diode with a glass-passivated junction, enabling fast response (<1 ns) to transient overvoltages. Its breakdown voltage is specified at 9.5–10.5 V with 1 mA test current, and it exhibits low incremental surge resistance to maintain stable clamping during repetitive 10/1000 µs pulses.
Thermally, it has a junction-to-ambient thermal resistance of 120 °C/W and a maximum operating junction temperature of 150 °C. It is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine) and meets MSL Level 1 per J-STD-020 with peak reflow at 260 °C.
Key Specifications

|---|---|
| VWM (Stand-off Voltage) | 8.55 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 9.5–10.5 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 14.5 V at 27.6 A - Peak voltage seen by protected circuit during 10/1000 µs surge; critical for downstream IC voltage tolerance. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standard lightning/surge waveform; enables robust protection in 24 V systems. |
| ID (Reverse Leakage) | 10 µA max at 8.55 V - Minimal standby current leakage; preserves low-power system integrity. |
| TJ max | 150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial ambient environments. |
| RθJA | 120 °C/W - Thermal resistance defining self-heating under DC bias; informs pad layout and airflow requirements. |

Use Scenario: Protection of gate drivers and microcontroller I/O pins from inductive kickback generated by solenoid and relay coils in PLC output stages. IC Role / Device Role: Unidirectional TVS placed between driver output and ground to clamp negative transients and prevent latch-up. Use Value: 14.5 V clamping ensures MCU GPIOs (typically rated to 16 V absolute max) remain within safe operating limits during 40 A coil turn-off events. |
Use Scenario: Safeguarding LIN bus transceivers and sensor supply lines against load dump and jump-start transients in door module ECUs. IC Role / Device Role: Standoff-clamp TVS on 12 V rail upstream of LDO regulators to limit input voltage excursions during ISO 7637-2 Pulse 5a events. Use Value: 8.55 V VWM provides 35 % margin above nominal 12 V system, while 400 W rating handles 100 ms load dump energy without degradation. |
| Consumer Power Adapter | Telecom Interface Protection |
|
Use Scenario: Secondary-side overvoltage suppression on 5 V/3.3 V outputs of AC-DC adapters exposed to ESD and capacitive coupling noise. IC Role / Device Role: Low-leakage (10 µA) unidirectional TVS shunting transient energy to ground before reaching USB controller or PMIC. Use Value: 10.5 V VBR ensures no conduction during normal 5.5 V max output ripple, eliminating false triggering during regulation. |
Use Scenario: Front-end protection of RS-485 transceivers connected to long external cables susceptible to lightning-induced surges. IC Role / Device Role: Primary-stage TVS on differential pair (A/B lines) referenced to ground, limiting common-mode overvoltage. Use Value: 14.5 V VC clamps induced surges below RS-485 receiver common-mode range (−7 V to +12 V), preventing damage or data corruption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A (Bourns) | Same VWM (8.55 V), higher VC (16.7 V), larger SMB (DO-214AA) package (4.5 × 3.9 mm vs. 4.5 × 2.7 mm). | Lower power density; requires more PCB area; better thermal dissipation under sustained surges. | Select SMBJ10A only if board layout allows larger footprint and higher clamping voltage is acceptable. |
| 1.5SMC10A (ON Semiconductor) | Identical VWM and VC specs, but in larger SMC (DO-214AB) package (7.1 × 6.2 mm); 1500 W PPPM rating. | Over-specified for 400 W needs; suited for high-energy industrial surge environments where redundancy is required. | Choose 1.5SMC10A only when system-level surge testing demands >1000 W margin or legacy SMC footprint compatibility is mandatory. |
Compared with SMBJ10A and 1.5SMC10A, the P4SMA10A-E3/61 delivers optimal space-constrained protection for 400 W surge events with minimal PCB footprint and precise 14.5 V clamping - making it ideal for dense consumer and automotive electronics where layout area and voltage margin are critical.

FAQ
What is the maximum clamping voltage of the P4SMA10A-E3/61 under a 10/1000 µs surge?
The P4SMA10A-E3/61 has a maximum clamping voltage (VC) of 14.5 V at 27.6 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions and defines the highest voltage the protected circuit will experience during such a transient. The P4SMA10A-E3/61 maintains this clamping performance across its rated junction temperature range and is validated in Vishay's official datasheet revision 09-Jan-2024.
Is the P4SMA10A-E3/61 RoHS-compliant and halogen-free?
Yes, the P4SMA10A-E3/61 carries the "E3" suffix, indicating it is RoHS-compliant and manufactured to Vishay's commercial-grade specifications. It is not halogen-free - that designation applies to "M3" suffix variants (e.g., P4SMA10A-M3/61). The P4SMA10A-E3/61 uses standard molding compound meeting UL 94 V-0 and passes JESD 201 Class 2 whisker testing.
Does the P4SMA10A-E3/61 have AEC-Q101 qualification?
No, the P4SMA10A-E3/61 is a commercial-grade part and is not AEC-Q101 qualified. However, the same die and package are offered in AEC-Q101 qualified versions under ordering codes such as P4SMA10AHE3_A/H (with "HE3" suffix and revision code). The P4SMA10A-E3/61 shares identical electrical and thermal characteristics but lacks the extended automotive qualification testing and traceability documentation.
What is the thermal resistance and maximum junction temperature of the P4SMA10A-E3/61?
The P4SMA10A-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and a maximum operating junction temperature (TJ max) of +150 °C. These values assume mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Derating curves in the Vishay datasheet show power capability decreases linearly above 25 °C ambient, and the P4SMA10A-E3/61 remains functional up to TJ = 150 °C without parametric shift.
How does the P4SMA10A-E3/61 differ from bidirectional variants like P4SMA10CA?
The P4SMA10A-E3/61 is unidirectional and conducts only in reverse bias above VBR, with polarity marked by a cathode band. In contrast, P4SMA10CA is bidirectional - symmetrical in both directions, with no polarity marking and identical VBR/VWM in positive and negative quadrants. The P4SMA10A-E3/61 is selected for DC-coupled lines where polarity is fixed (e.g., 12 V supply rails), whereas P4SMA10CA suits AC or differential signal lines like RS-485.
