Product details
Overview
SMAJ16AE3/TR13 from Microsemi is a unidirectional surface-mount transient voltage suppressor (TVS) designed for primary overvoltage protection of DC power rails and signal lines. It features a 16 V reverse standoff voltage (VWM), 17.8 V minimum breakdown voltage (VBR), 26.0 V maximum clamping voltage (VC) at 19.2 A peak pulse current, and 500 W peak pulse power rating per 10/1000 µs waveform-used in industrial power supplies and automotive control modules.
For engineers reviewing the SMAJ16AE3/TR13 datasheet, SMAJ16AE3/TR13 pinout, SMAJ16AE3/TR13 application, or SMAJ16AE3/TR13 equivalent, key selection criteria include clamping performance under IEC61000-4-5 secondary lightning surge (12 Ω source, Class 2), RoHS-compliant matte-tin plating, and DO-214AC package compatibility with standard SMT reflow profiles.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds VBR = 17.8 V (tested at IBR = 1 mA). Its <100 ps theoretical response time enables effective suppression of ESD per IEC61000-4-2 (±8 kV contact) and EFT per IEC61000-4-4 (±2 kV).
The device is rated for continuous operation from –65 °C to +150 °C, with thermal resistance of 15 °C/W junction-to-lead and 80 °C/W junction-to-ambient on FR4 (1 oz Cu). Its 0.064 g mass and DO-214AC outline support high-density PCB layouts in space-constrained applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16AHE3/TR13 | Same electrical specs but with enhanced screening (avionics-grade temperature cycling, HTRB, surge testing) | Required for aerospace or defense systems requiring MIL-PRF-19500 JANTX-level reliability | Select SMAJ16AHE3/TR13 only if extended qualification testing is mandated by program requirements |
| SMCJ16A-E3/57T | Higher 1500 W rating in DO-214AB (SMC) package; 27.7 V clamping at 54.3 A | Used where higher surge energy handling is needed, but requires larger PCB footprint and layout revision | Choose SMCJ16A-E3/57T only when system-level surge tests exceed 500 W capability of SMAJ16AE3/TR13 |
Compared with SMAJ16AE3/TR13, SMAJ16AHE3/TR13 adds avionics screening without changing clamping behavior, while SMCJ16A-E3/57T trades compact DO-214AC size for 3× higher surge capacity in a larger package-neither is pin-compatible, but both serve overlapping protection roles in different mechanical or reliability contexts.

FAQ
What is the clamping voltage of SMAJ16AE3/TR13 under a 10/1000 µs surge?
The SMAJ16AE3/TR13 has a maximum clamping voltage (VC) of 26.0 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 19.2 A. This value is measured per Figure 2 in the official Microsemi MSC0270A datasheet and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is SMAJ16AE3/TR13 unidirectional or bidirectional?
SMAJ16AE3/TR13 is a unidirectional TVS diode, indicated by the absence of "C" or "CA" in its part number suffix. It conducts only in reverse bias above VBR, with cathode marked by a band on the DO-214AC package. Bidirectional variants (e.g., SMAJ16CAE3/TR13) are separate orderables with symmetrical clamping in both polarities.
Does SMAJ16AE3/TR13 meet IEC61000-4-5 for lightning surge protection?
Yes, SMAJ16AE3/TR13 is rated for secondary lightning protection per IEC61000-4-5 with 12 Ω source impedance at Class 2 level (up to 1 kV test voltage), as confirmed in the Applications/Benefits section of the MSC0270A datasheet. Its 500 W rating and 26.0 V clamping ensure compliance when used with appropriate PCB layout and grounding.
What is the moisture sensitivity level (MSL) of SMAJ16AE3/TR13?
SMAJ16AE3/TR13 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry packing or baking prior to reflow. This simplifies manufacturing logistics and eliminates floor-life tracking for standard SMT assembly.
Can SMAJ16AE3/TR13 replace SMAJ16A in existing designs?
Yes, SMAJ16AE3/TR13 is a direct replacement for SMAJ16A with identical electrical specifications and DO-214AC packaging. The "e3" suffix denotes RoHS-compliant matte-tin plating, and "TR13" indicates 2500-piece tape-and-reel packaging per EIA-481-1-A-both enhancements that maintain full form-fit-function compatibility with legacy SMAJ16A footprints and layouts.
