Product details
Overview
SMA5J16-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-214AC (SMA) package, designed for high-energy surge protection on power and signal lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 26.0 V clamping voltage (VC) at 19.2 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMA5J16-E3/61 datasheet, SMA5J16-E3/61 pinout, SMA5J16-E3/61 application, or SMA5J16-E3/61 equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, AEC-Q101 qualification (via HE3 variant), RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a silicon avalanche diode optimized for transient suppression in DC power rails and low-speed signal paths. Its glass-passivated junction ensures stable breakdown characteristics, while low incremental surge resistance enables tight clamping during fast transients (e.g., ISO 7637-2 load dump or IEC 61000-4-5 surges).
The SMA5J16-E3/61 is rated for non-repetitive 10/1000 µs pulses up to 500 W, with thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead). It complies with J-STD-020 MSL Level 1 and passes JESD 201 Class 1A whisker testing - confirming suitability for high-reliability surface-mount assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J16AHE3/61 | AEC-Q101 qualified; identical electrical specs but enhanced reliability screening for automotive use. | Required for automotive OEM designs where component qualification is mandatory. | Select SMA5J16AHE3/61 when automotive qualification is required; SMA5J16-E3/61 suffices for commercial/industrial use. |
| SMC5J16A-E3/57T | DO-214AB (SMC) package; same VWM/VC, but higher 2000 W PPPM and larger 7.11 mm × 6.22 mm footprint. | Used where higher surge energy absorption is needed and board space allows larger package. | Choose SMC5J16A-E3/57T only if 2000 W surge rating is required; SMA5J16-E3/61 offers optimal power density for space-constrained layouts. |
Compared with SMA5J16AHE3/61, the SMA5J16-E3/61 omits automotive qualification screening but retains identical clamping performance and thermal behavior; versus SMC5J16A-E3/57T, it delivers 500 W protection in 40% less PCB area - prioritizing compactness over extreme surge capacity.

FAQ
What is the clamping voltage of the SMA5J16-E3/61 under maximum surge conditions?
The SMA5J16-E3/61 exhibits a maximum clamping voltage (VC) of 26.0 V at 19.2 A peak pulse current (IPPM) using a 10/1000 µs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream components like 30 V-rated MOSFETs remain within safe operating area.
Is the SMA5J16-E3/61 suitable for automotive applications?
The SMA5J16-E3/61 is RoHS-compliant and manufactured to Vishay's commercial-grade specifications. While it shares identical electrical characteristics with the AEC-Q101-qualified SMA5J16AHE3/61, the SMA5J16-E3/61 itself is not AEC-Q101 certified. For automotive OEM designs, the HE3-suffixed variant must be selected; SMA5J16-E3/61 remains appropriate for non-automotive industrial and consumer applications.
What is the thermal resistance of the SMA5J16-E3/61, and how does it affect PCB layout?
The SMA5J16-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout; reducing pad size increases thermal impedance and may require derating peak power. Layout must follow Vishay's DO-214AC mounting guidelines to maintain 150 °C TJ capability.
Does the SMA5J16-E3/61 have polarity marking, and how is it oriented on the PCB?
Yes - the SMA5J16-E3/61 is unidirectional and marked with a cathode band at one end of the DO-214AC (SMA) package. During PCB layout, the banded end must connect to ground or the lower-potential reference node, while the anode connects to the line being protected. Incorrect orientation prevents proper clamping and may result in catastrophic failure during surge events.
What is the peak pulse current rating of the SMA5J16-E3/61, and how is it derived?
The SMA5J16-E3/61 supports a peak pulse current (IPPM) of 19.2 A under a 10/1000 µs waveform, calculated from its 500 W peak pulse power (PPPM) and 26.0 V clamping voltage (VC) using IPPM = PPPM/VC. This rating assumes single-event, non-repetitive surge conditions and must be derated for elevated ambient temperatures per Figure 2 in the Vishay datasheet 88875.
