Product details
Overview
SMA5J8.0CHE3/61 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 8.0 V stand-off voltage (VWM), 13.6 V clamping voltage (VC) at 36.8 A peak pulse current (IPPM), and 500 W peak pulse power (10/1000 µs waveform), qualified to AEC-Q101 for automotive electronics.
For engineers reviewing the SMA5J8.0CHE3/61 datasheet, SMA5J8.0CHE3/61 pinout, SMA5J8.0CHE3/61 application, or SMA5J8.0CHE3/61 equivalent, key selection criteria include bi-directional clamping capability, low incremental surge resistance, MSL Level 1 moisture sensitivity, and RoHS-compliant AEC-Q101 qualification for harsh-environment deployment.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 8.89 V and 9.83 V at 1 mA test current. Its clamping performance is characterized under standardized 10/1000 µs surge waveforms, delivering 13.6 V maximum clamping voltage at 36.8 A IPPM.
Thermal design relies on junction-to-lead thermal resistance of 25 °C/W and junction-to-ambient of 80 °C/W (on 5.0 mm × 5.0 mm copper pads). It supports operating junction temperatures from –55 °C to +150 °C and meets JESD201 Class 2 whisker resistance via HE3 suffix.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J8.0AHE3/61 | Same electrical specs and AEC-Q101 qualification; differs only in packaging code (HE3 denotes AEC-Q101 grade, identical to SMA5J8.0CHE3/61) | No functional difference - both are bi-directional, AEC-Q101 qualified, DO-214AC packaged TVS diodes | Select SMA5J8.0CHE3/61 when ordering from standard Vishay commercial-AEC blended reels; verify reel code compatibility with assembly line feeders |
| SMCJ8.0CAHE3/61 | Higher 1500 W PPPM, larger DO-214AB (SMC) package (7.11 mm × 6.22 mm), same VWM/VC ratings | Suitable where higher surge energy absorption is required and PCB space allows larger footprint | Choose SMCJ8.0CAHE3/61 only if system-level testing confirms need for >500 W surge handling; avoid if board area or height constraints apply |
Compared with SMA5J8.0CHE3/61, SMA5J8.0AHE3/61 offers identical protection performance in the same footprint, while SMCJ8.0CAHE3/61 trades compactness for 3× higher pulse power - making SMA5J8.0CHE3/61 optimal for space-constrained automotive and industrial PCBs requiring certified bi-directional clamping.

FAQ
What does the "HE3" suffix indicate in SMA5J8.0CHE3/61?
The "HE3" suffix in SMA5J8.0CHE3/61 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. It confirms the device meets automotive-grade reliability requirements including thermal cycling, humidity resistance, and long-term solderability - distinct from commercial-grade "E3" variants. SMA5J8.0CHE3/61 is fully specified for use in automotive ECUs and ADAS modules.
Is SMA5J8.0CHE3/61 unidirectional or bidirectional, and how is polarity marked?
SMA5J8.0CHE3/61 is a bi-directional TVS diode, meaning it provides symmetrical clamping in both forward and reverse bias conditions. As confirmed in the Vishay datasheet, bi-directional types like SMA5J8.0CHE3/61 have no cathode band or polarity marking - both terminals are functionally identical. This eliminates orientation errors during automated placement and simplifies layout for differential or AC-coupled lines.
What is the maximum clamping voltage of SMA5J8.0CHE3/61 under surge conditions?
The maximum clamping voltage (VC) of SMA5J8.0CHE3/61 is 13.6 V, measured at its rated peak pulse current (IPPM) of 36.8 A under a standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring compatibility with 16 V-tolerant downstream ICs.
Does SMA5J8.0CHE3/61 require derating at elevated ambient temperatures?
Yes, SMA5J8.0CHE3/61 requires derating above TA = 25 °C, as shown in Figure 2 of the Vishay datasheet. Its peak pulse power (PPPM) decreases linearly to zero at +150 °C junction temperature. At 85 °C ambient (with proper PCB copper pad thermal relief), usable PPPM drops to approximately 350 W. Designers must apply thermal modeling using RθJA = 80 °C/W and RθJL = 25 °C/W to ensure safe operation.
Can SMA5J8.0CHE3/61 be used in place of SMA5J8.0AHE3/61?
Yes, SMA5J8.0CHE3/61 and SMA5J8.0AHE3/61 are electrically and mechanically identical - both are bi-directional, AEC-Q101 qualified, DO-214AC packaged TVS diodes with identical VWM, VBR, VC, and PPPM specifications. The "C" in SMA5J8.0CHE3/61 explicitly confirms bi-directionality per Vishay's naming convention; no redesign or layout change is needed when substituting between these two orderable part numbers.
