Product details
Overview
SMA5J13CHE3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on power and signal lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), 23.3 A peak pulse current (IPPM), and clamps to ≤21.5 V at rated surge. It is AEC-Q101 qualified and used in automotive power rail protection.
For engineers reviewing the SMA5J13CHE3/61 datasheet, SMA5J13CHE3/61 pinout, SMA5J13CHE3/61 application, or SMA5J13CHE3/61 equivalent, key selection criteria include unidirectional polarity, 13 V operating threshold, DO-214AC thermal resistance (RθJA = 80 °C/W), RoHS-compliant matte tin plating, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds VBR, limiting transient energy to protected downstream circuitry. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns).
Designed for 10/1000 µs surge waveforms per IEC 61000-4-5, it delivers 500 W peak pulse power with low incremental surge resistance and clamps at 21.5 V under 23.3 A surge. Thermal performance is characterized by RθJA = 80 °C/W (on 5.0 mm × 5.0 mm copper pads) and RθJL = 25 °C/W.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J13A-E3/61 | Same electrical specs but commercial-grade (non-AEC-Q101); no HE3 whisker qualification | Lacks automotive qualification; suitable for industrial/commercial power supplies only | Select if AEC-Q101 is not required and cost optimization is prioritized |
| SMC5J13AHE3/A | Same VWM/VBR/PPPM, but in larger DO-214AB (SMC) package with higher IPPM (33.3 A) | Higher surge margin and better thermal dissipation; requires larger PCB footprint | Choose when system-level surge testing exceeds 500 W or board layout allows SMC footprint |
Compared with SMA5J13A-E3/61, SMA5J13CHE3/61 adds AEC-Q101 and JESD 201 Class 2 whisker resistance for automotive use; compared with SMC5J13AHE3/A, it trades surge headroom for compact DO-214AC size-ideal where space is constrained but 500 W compliance suffices.

FAQ
What is the polarity configuration of SMA5J13CHE3/61?
SMA5J13CHE3/61 is a unidirectional transient voltage suppressor diode. Its cathode is marked by a band on the DO-214AC package body, and it conducts in reverse bias during overvoltage events. This polarity enables precise clamping on positive-going transients in DC power lines, unlike bi-directional variants which protect both polarities.
Does SMA5J13CHE3/61 meet automotive qualification standards?
Yes, SMA5J13CHE3/61 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control, body electronics, and infotainment systems. The HE3 suffix denotes compliance with JESD 201 Class 2 whisker resistance and RoHS requirements, supporting under-hood reliability.
What is the maximum clamping voltage of SMA5J13CHE3/61 under surge conditions?
The maximum clamping voltage (VC) of SMA5J13CHE3/61 is 21.5 V when subjected to its rated peak pulse current of 23.3 A (10/1000 µs waveform). This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during transient events.
How does the DO-214AC package of SMA5J13CHE3/61 affect thermal performance?
SMA5J13CHE3/61 in DO-214AC (SMA) package has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. This thermal characteristic supports continuous operation up to +150 °C junction temperature in compact automotive modules with limited airflow.
Is SMA5J13CHE3/61 compatible with lead-free reflow soldering processes?
Yes, SMA5J13CHE3/61 meets MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, making it fully compatible with standard lead-free soldering profiles. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for reliable wetting and intermetallic formation.
