Overview
P4SMA16AHE3/5A 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 16 V standoff voltage (VWM), 17.8 V maximum clamping voltage at 1 A peak pulse current, 400 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the P4SMA16AHE3/5A datasheet, P4SMA16AHE3/5A pinout, P4SMA16AHE3/5A application, or P4SMA16AHE3/5A equivalent, this device is selected for robust overvoltage protection in DC power rails, sensor interfaces, and MOSFET gate drivers where low clamping voltage, fast response (<1 ns), and high surge reliability are required.
Technical Context
The P4SMA16AHE3/5A operates as a unidirectional avalanche diode with cathode-banded polarity, leveraging glass-passivated junction technology for stable breakdown behavior and low leakage (<1 µA at 13.6 V). Its thermal resistance (RθJA = 120 °C/W) and 150 °C max junction temperature support operation in compact PCB layouts with minimal copper area.
It delivers 400 W peak pulse power under standardized 10/1000 µs waveform conditions when mounted on 5.0 mm × 5.0 mm copper pads, with derated capability above 25 °C ambient per Fig. 2. The device exhibits 0.086 %/°C temperature coefficient of breakdown voltage and meets J-STD-020 MSL Level 1 reflow profile (260 °C peak).

IC Role / Device Role / Timing Role: Low-capacitance TVS on signal lines to absorb ESD (IEC 61000-4-2 ±8 kV contact) without distorting millivolt-level signals. Use Value: Sub-1 µA leakage at 13.6 V prevents loading of high-impedance sensor bridges or op-amp inputs. |
| DC-DC Converter Input Protection | MOSFET Gate Driver Transient Suppression |
Use Scenario: Front-end protection for buck/boost converters in telecom power supplies exposed to AC line surges and hot-swap transients. IC Role / Device Role / Timing Role: Primary surge clamp on VIN rail upstream of input filter capacitors and controller ICs. Use Value: 400 W rating handles repetitive 10/1000 µs surges up to 0.01% duty cycle, matching typical telecom surge test profiles. |
Use Scenario: Preventing gate oxide damage in high-side N-channel MOSFET drivers subjected to Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Fast-response TVS across gate-source terminals to limit VGS excursion during switching transitions. Use Value: <1 ns response time ensures clamping occurs before gate driver propagation delay (~10–50 ns), preserving FET reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5A (Vishay) | Same VWM (13.6 V), same package, but 400 W rating applies only up to 91 V; P4SMA16AHE3/5A maintains full 400 W rating. | Not AEC-Q101 qualified; suitable for commercial/industrial, not automotive. | Select P4SMA16AHE3/5A when AEC-Q101 compliance and consistent 400 W performance are mandatory. |
| 1.5SMC16A (ON Semiconductor) | Same VWM (13.6 V), same 400 W rating, but SMC (DO-214AB) package - 2.5 mm wider than SMA, requiring PCB layout change. | Also AEC-Q101 qualified (1.5SMC16AQ), but larger footprint limits use in space-constrained modules. | Choose P4SMA16AHE3/5A for tighter board space and identical SMA footprint compatibility with existing designs. |
Compared with SMAJ16A-E3/5A and 1.5SMC16A, the P4SMA16AHE3/5A uniquely combines AEC-Q101 qualification, full 400 W rating across its entire operating range, and the smallest standardized surface-mount TVS footprint (SMA), enabling drop-in replacement in automotive and high-density industrial layouts without sacrificing surge margin.

FAQ
What is the maximum clamping voltage of the P4SMA16AHE3/5A under surge conditions?
The P4SMA16AHE3/5A has a maximum clamping voltage (VC) of 22.5 V at 1 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 transient events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is the P4SMA16AHE3/5A suitable for automotive applications?
Yes, the P4SMA16AHE3/5A is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 09-Jan-2024. Its qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing per AEC standards, making it suitable for under-hood and cabin electronics including body control modules, lighting drivers, and infotainment power supplies where automotive-grade reliability is mandated.
What does the "HE3" suffix indicate in P4SMA16AHE3/5A?
The "HE3" suffix in P4SMA16AHE3/5A denotes RoHS-compliant construction and AEC-Q101 qualification per Vishay's ordering nomenclature. Specifically, "H" indicates AEC-Q101 qualification, "E3" signifies RoHS-compliant (lead-free) matte tin plating, and "/5A" specifies packaging in 13-inch tape-and-reel with 7500 units per reel - all verified in the Ordering Information table on page 3 of document 88367.
How does the P4SMA16AHE3/5A compare to bidirectional TVS diodes like P4SMA16CA?
The P4SMA16AHE3/5A is unidirectional and intended for DC line protection where polarity is fixed (e.g., +12 V rail to GND), offering lower leakage and higher surge margin in one direction. In contrast, P4SMA16CA is bidirectional and used for AC or floating signal lines (e.g., RS-485, CAN), with symmetric clamping but higher leakage at VWM. The P4SMA16AHE3/5A cannot replace P4SMA16CA in AC-coupled applications due to polarity dependence.
What is the thermal resistance and maximum junction temperature of the P4SMA16AHE3/5A?
The P4SMA16AHE3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on minimum recommended pad layout (0.2" × 0.2" copper), and a maximum junction temperature (TJ) of +150 °C. These values are specified in the Thermal Characteristics table (page 3) and enable reliable operation in ambient temperatures up to +125 °C when proper PCB copper area is provided.
