Product details
Overview
SMAJ6.0E3/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 6.0 V working peak standoff voltage (VWM), 6.67 V minimum breakdown voltage (VBR) at 10 mA, 10.3 V maximum clamping voltage (VC) at 48.5 A peak pulse current, and 500 W peak pulse power rating per 10/1000 µs waveform-used in industrial power supplies, automotive body control modules, and USB port ESD hardening.
For engineers reviewing the SMAJ6.0E3/TR13 datasheet, SMAJ6.0E3/TR13 pinout, SMAJ6.0E3/TR13 application, or SMAJ6.0E3/TR13 equivalent, this page delivers verified electrical parameters, IEC61000-4-2/4-4/4-5 compliance context, DO-214AC package layout, and RoHS-compliant unidirectional TVS selection guidance for high-reliability PCB-level surge suppression.
Technical Context
The SMAJ6.0E3/TR13 operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its 6.67 V breakdown threshold. Its sub-100 ps theoretical response time enables effective suppression of electrostatic discharge (ESD) events and fast-rising switching transients.
It is rated for 500 W peak pulse power at 25 °C using the standardized 10/1000 µs double-exponential waveform, with thermal resistance of 15 °C/W junction-to-lead and 80 °C/W junction-to-ambient on FR4 board. Standby leakage remains ≤800 µA at 6.0 V VWM, supporting low-power system integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; sets DC rail compatibility limit. |
| VBR (Min @ IBR) | 6.67 V @ 10 mA - Guaranteed avalanche initiation threshold; ensures predictable turn-on margin above VWM. |
| VC @ IPP | 10.3 V @ 48.5 A - Clamped voltage during 500 W surge; defines worst-case protected-circuit overvoltage stress. |
| PPP | 500 W @ 10/1000 µs - Peak transient energy handling capacity; validates suitability for IEC61000-4-5 Class 4 secondary lightning. |
| ID @ VWM | ≤800 µA - Reverse leakage at rated standoff; ensures minimal quiescent power loss in battery-powered systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | Same VWM (6.0 V), lower VC (10.3 V vs. 10.3 V), identical IPP (48.5 A), but non-RoHS (SnPb plating). | Not suitable for new RoHS-compliant designs; requires leaded assembly process and fails EU WEEE compliance reporting. | Select SMAJ6.0A only for legacy repair or military avionics programs requiring SnPb finish and MA/MX screening. |
| SMBJ6.0A-E3/52 | Same VWM/VBR/VC, but SMB (DO-214AA) package - 20% smaller footprint, 400 W rating (vs. 500 W), higher thermal resistance. | Lower power handling limits use in high-energy surge environments (e.g., outdoor metering); reduced creepage/clearance may affect safety certification. | Choose SMBJ6.0A-E3/52 only when board space is constrained and peak surge energy is confirmed ≤400 W per IEC61000-4-5 test plan. |
Compared with SMAJ6.0A and SMBJ6.0A-E3/52, SMAJ6.0E3/TR13 uniquely combines RoHS compliance, full 500 W surge rating, and DO-214AC thermal performance - making it the preferred choice for new industrial and automotive designs requiring both regulatory alignment and robust transient immunity.

FAQ
What is the clamping voltage of SMAJ6.0E3/TR13 at its rated peak pulse current?
The SMAJ6.0E3/TR13 has a maximum clamping voltage (VC) of 10.3 V at 48.5 A peak pulse current (IPP) under the 10/1000 µs waveform. This value is measured per Figure 2 in the official Microsemi datasheet MSC0270A and defines the upper voltage limit imposed on protected circuitry during a full-rated 500 W transient event.
Is SMAJ6.0E3/TR13 unidirectional or bidirectional?
SMAJ6.0E3/TR13 is a unidirectional transient voltage suppressor, indicated by the absence of "C" or "CA" in its part number. It conducts only in reverse bias (cathode-to-anode), making it suitable for DC power rail protection where forward conduction must be blocked - unlike bidirectional variants such as SMAJ6.0CAE3/TR13.
Does SMAJ6.0E3/TR13 meet IEC61000-4-5 Class 4 lightning surge requirements?
Yes, SMAJ6.0E3/TR13 meets IEC61000-4-5 Class 4 secondary lightning protection when tested with 42 Ω source impedance, as confirmed in the Microsemi datasheet's Applications/Benefits section. Its 500 W rating and 10.3 V clamping voltage ensure compliance for 12 V systems with defined coupling network parameters.
What is the package type and mounting style of SMAJ6.0E3/TR13?
SMAJ6.0E3/TR13 uses the DO-214AC (SMA) surface-mount package with C-bend leads, conforming to JEDEC standards. It is designed for reflow soldering on FR4 PCBs using the recommended pad layout on page 5 of MSC0270A, and carries MSL Level 1 rating - no dry pack or baking required prior to assembly.
What does the "TR13" suffix indicate in SMAJ6.0E3/TR13?
The "TR13" suffix denotes tape-and-reel packaging per EIA-481-1-A standard: 12 mm carrier tape, 2500 units per 13-inch reel. This format supports automated SMT placement and is distinct from the "TR" variant (750 units per 7-inch reel) - both share identical electrical and mechanical specifications.
