Product details
Overview
SMA5J6.0CHE3/61 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on signal and power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps transients to ≤10.3 V at 48.5 A IPPM. It is AEC-Q101 qualified and used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J6.0CHE3/61 datasheet, SMA5J6.0CHE3/61 pinout, SMA5J6.0CHE3/61 application, or SMA5J6.0CHE3/61 equivalent, key selection criteria include bi-directional clamping capability, 150 °C junction temperature rating, RoHS-compliant HE3 suffix qualification, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, enabling robust protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports fast clamping response under 10/1000 μs transients.
The device is rated for 500 W peak pulse power per JEDEC-standard 10/1000 μs waveform, with thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W. It meets MSL Level 1 (260 °C reflow) and is qualified to AEC-Q101 for automotive under-hood and chassis applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0AHE3/61 | Same electrical specs; identical HE3 suffix (AEC-Q101 qualified), same packaging (61 = 7" tape/reel) | No functional difference; alternate ordering code with identical form, fit, and function | Select when matching exact Vishay internal part numbering convention for procurement systems |
| SMC5J6.0CA | Higher power rating (1500 W PPPM), larger DO-214AB (SMC) package, same VWM/VBR/VC specs | Used where higher surge energy absorption is required (e.g., main power rail vs. signal line) | Choose for >500 W surge environments; requires PCB layout change due to larger footprint |
Compared with SMA5J6.0CHE3/61, SMA5J6.0AHE3/61 is an identical device under alternate part numbering, while SMC5J6.0CA offers triple the pulse power in a physically larger package-enabling higher energy handling but requiring board redesign.

FAQ
What is the polarity configuration of SMA5J6.0CHE3/61?
SMA5J6.0CHE3/61 is a bi-directional TVS diode with no polarity marking on the DO-214AC (SMA) package. Its electrical characteristics-including breakdown voltage, clamping voltage, and leakage-are identical in both directions, making it suitable for protecting AC-coupled signals, differential buses, or floating nodes without orientation constraints. This symmetry is confirmed in the Vishay datasheet Document Number 88875, Section "DEVICES FOR BI-DIRECTION APPLICATIONS".
Does SMA5J6.0CHE3/61 meet automotive qualification standards?
Yes, SMA5J6.0CHE3/61 is explicitly AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number and verified in the Vishay datasheet revision 24-Oct-12. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming its suitability for automotive applications such as engine control units, ADAS sensor interfaces, and infotainment system I/O protection.
What is the maximum clamping voltage of SMA5J6.0CHE3/61 under surge conditions?
The maximum clamping voltage (VC) of SMA5J6.0CHE3/61 is 10.3 V, measured at its peak pulse current (IPPM) of 48.5 A under a standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on the protected circuit during worst-case transient events and is guaranteed across the full operating temperature range per the Vishay datasheet Table "ELECTRICAL CHARACTERISTICS".
How does the HE3 suffix differ from the E3 suffix in SMA5J6.0CHE3/61?
The HE3 suffix in SMA5J6.0CHE3/61 denotes RoHS compliance plus AEC-Q101 qualification, whereas the E3 suffix indicates RoHS compliance only (commercial grade). The "H" prefix specifically identifies the automotive-qualified variant, validated for extended temperature operation (−55 °C to +150 °C), enhanced reliability testing, and whisker resistance per JESD 201 Class 2-critical for automotive and industrial deployments where long-term field stability is mandatory.
What PCB pad layout is recommended for optimal thermal performance of SMA5J6.0CHE3/61?
Vishay specifies mounting SMA5J6.0CHE3/61 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated thermal resistance (RθJA = 80 °C/W) and 500 W pulse power handling. Deviating from this layout-such as using smaller pads or insufficient copper area-reduces heat dissipation, increases junction temperature, and may cause premature failure during repetitive surges. The recommendation appears in the "MECHANICAL DATA" section of datasheet 88875.
