Product details
Overview
P4SMA16AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features a 13.6 V stand-off voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA, 22.5 V maximum clamping voltage (VC) at 17.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - suitable for protecting MOSFET gates, sensor interfaces, and low-voltage DC rails in automotive and industrial control modules.
For engineers reviewing the P4SMA16AHE3/61 datasheet, P4SMA16AHE3/61 pinout, P4SMA16AHE3/61 application, or P4SMA16AHE3/61 equivalent, this device delivers AEC-Q101 qualification, MSL Level 1 moisture sensitivity, glass-passivated junction reliability, and verified clamping performance under repetitive 0.01% duty-cycle surges - critical for robust front-end protection in safety-conscious designs.
Technical Context
The P4SMA16AHE3/61 operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified breakdown range (15.2–16.8 V). Its low incremental surge resistance and sub-nanosecond response time enable effective suppression of fast transients induced by inductive switching or ESD events.
Thermally, it exhibits RθJA = 120 °C/W and RθJL = 30 °C/W, with a maximum junction temperature of +150 °C and power dissipation of 3.3 W on infinite heatsink at 50 °C ambient. The cathode band denotes polarity, and matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.

Applications
| Automotive Sensor Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting analog outputs of pressure/temperature sensors in engine bay or transmission control modules exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output line and chassis ground to clamp transients before reaching ADC input or op-amp buffer. Use Value: Limits clamped voltage to 22.5 V during 400 W surges, preventing latch-up or damage to 3.3 V/5 V signal-conditioning ICs while maintaining <1 µA leakage at 13.6 V nominal. |
Use Scenario: Safeguarding 24 V digital input channels on programmable logic controllers subjected to relay coil flyback and field-wiring ESD. IC Role / Device Role / Timing Role: Standoff-rated TVS on each input channel, shunting surge energy to common ground before reaching optocoupler or Schmitt trigger input stage. Use Value: Withstands 17.8 A peak pulse current and maintains 13.6 V working voltage, ensuring reliable detection of valid 15–30 V logic-high signals while rejecting >22.5 V threats. |
| Consumer Power Supply Clamp | MOSFET Gate Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters and USB PD chargers where 12–20 V rails may experience transformer ringing or feedback loop faults. IC Role / Device Role / Timing Role: Parallel-connected TVS across regulated output capacitor to clamp overshoot during dynamic load steps or regulation failure. Use Value: Fast response and 22.5 V clamping prevent overvoltage damage to connected devices (e.g., smartphones, IoT hubs) while supporting 400 W surge compliance. |
Use Scenario: Gate-source protection of N-channel power MOSFETs in motor drivers and DC-DC converters subject to Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Low-capacitance TVS placed directly across gate and source terminals to limit VGS to safe levels (<20 V) during switching transitions. Use Value: 15.2–16.8 V VBR aligns with typical 12 V gate drive rails; 22.5 V clamping prevents gate oxide rupture while adding negligible capacitance to high-speed switching nodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/61 | Same SMA package, identical VWM/VBR/VC, but rated for 400 W with 10/1000 µs waveform and not AEC-Q101 qualified. | Lacks automotive qualification; suitable for commercial/industrial use only where AEC-Q101 is not mandated. | Select SMAJ16A-E3/61 for cost-sensitive non-automotive designs requiring identical electrical specs without automotive validation. |
| 1.5SMC16A | Higher-power 1500 W SMC package; same VWM (13.6 V) and VC (22.5 V), but larger footprint and higher thermal mass. | Used where higher single-pulse energy absorption is required (e.g., primary-side AC line protection), not PCB-space-constrained locations. | Choose 1.5SMC16A only when surge energy exceeds 400 W capability and board layout allows SMC (DO-214AB) footprint. |
Compared with SMAJ16A-E3/61 and 1.5SMC16A, the P4SMA16AHE3/61 uniquely combines AEC-Q101 qualification, SMA package compactness, and verified 400 W clamping performance - making it the preferred choice for space-limited automotive and industrial edge nodes requiring certified reliability.

FAQ
What is the clamping voltage of the P4SMA16AHE3/61 under peak surge conditions?
The P4SMA16AHE3/61 has a maximum clamping voltage (VC) of 22.5 V at 17.8 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and represents the upper voltage limit imposed on the protected circuit during a 400 W transient event - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P4SMA16AHE3/61 suitable for automotive applications?
Yes, the P4SMA16AHE3/61 is AEC-Q101 qualified, explicitly listed in Vishay's ordering information as an automotive-grade variant (HE3 suffix). It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 requirements - making it approved for use in engine control units, ADAS sensors, and body electronics where reliability under harsh conditions is mandatory.
What does the "HE3/61" suffix indicate in P4SMA16AHE3/61?
The "HE3" suffix denotes RoHS-compliant and AEC-Q101-qualified construction, while "/61" specifies packaging in 7-inch diameter plastic tape-and-reel containing 1800 units. This ordering code ensures traceability, automotive qualification, and compatibility with standard SMT pick-and-place equipment - distinct from commercial-grade E3 or M3 variants.
How does the P4SMA16AHE3/61 compare to bidirectional TVS diodes like P4SMA16CA?
The P4SMA16AHE3/61 is unidirectional and intended for DC line protection with defined polarity (cathode band), whereas P4SMA16CA is bidirectional and used for AC or floating signal lines. Their VWM and VBR differ: P4SMA16AHE3/61 has 13.6 V VWM and 15.2–16.8 V VBR, while P4SMA16CA has 13.6 V VWM and 15.2–16.8 V VBR in both directions - but only the HE3 variant carries AEC-Q101 certification and automotive traceability.
What is the thermal resistance of the P4SMA16AHE3/61, and how does it affect layout design?
The P4SMA16AHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead (RθJL) of 30 °C/W. To maintain safe operation at full 400 W pulse rating, PCB layout must follow Vishay's recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad per terminal - insufficient copper area will cause excessive junction temperature rise and premature failure during repetitive surges.
