Product details
Overview
SMA5J7.5CHE3/61 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on signal and power lines. It features a 7.5 V stand-off voltage (VWM), 8.33–9.21 V breakdown voltage (VBR at 1.0 mA), 12.9 V maximum clamping voltage (VC) at 100 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMA5J7.5CHE3/61 datasheet, SMA5J7.5CHE3/61 pinout, SMA5J7.5CHE3/61 application, or SMA5J7.5CHE3/61 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, low incremental surge resistance, RoHS-compliant HE3 suffix, and thermal resistance of 80 °C/W junction-to-ambient.
Technical Context
This device operates symmetrically in both directions, with no polarity marking, making it suitable for AC-coupled or floating signal lines. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the DO-214AC package supports automated placement and meets MSL level 1 (260 °C reflow peak).
The SMA5J7.5CHE3/61 delivers 12.9 V clamping at 100 A IPPM under 10/1000 µs surge, with 1.0 µA max reverse leakage at 7.5 V and 150 °C maximum junction temperature - enabling robust protection in automotive power domains where load dump and ISO 7637-2 pulses are present.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J7.5CA-E3/61 | RoHS-compliant commercial-grade variant (E3 suffix); not AEC-Q101 qualified | Lacks automotive qualification; suitable for consumer or industrial non-automotive use | Select when AEC-Q101 is not required and cost sensitivity favors commercial grade |
| SMC5J7.5CAHE3/61 | Same electrical specs but in larger DO-214AB (SMC) package; RθJA = 35 °C/W vs. 80 °C/W | Higher surge handling margin due to lower thermal resistance; requires larger PCB footprint | Choose for higher-reliability power rail protection where board space permits and thermal performance is critical |
Compared with SMA5J7.5CHE3/61, the E3-suffix alternative lacks automotive qualification but offers identical clamping performance at lower cost, while the SMC5J7.5CAHE3/61 provides superior thermal dissipation in a larger package - enabling longer surge duration support in high-power industrial systems.

FAQ
What is the polarity configuration of SMA5J7.5CHE3/61?
The SMA5J7.5CHE3/61 is a bi-directional TVS diode with symmetrical terminals and no cathode band marking. Both ends function identically regardless of applied voltage polarity, enabling straightforward placement across AC-coupled or floating signal paths without orientation constraints. This design eliminates risk of incorrect installation in automated assembly and simplifies layout for differential interfaces. The SMA5J7.5CHE3/61 achieves this through matched P-N junctions fabricated on a single die.
Does SMA5J7.5CHE3/61 meet automotive qualification standards?
Yes, SMA5J7.5CHE3/61 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, ADAS sensors, and infotainment systems. The HE3 suffix explicitly denotes AEC-Q101 qualification, which covers stress tests such as temperature cycling, highly accelerated life testing (HALT), and humidity bias HTRB. This qualification ensures the SMA5J7.5CHE3/61 maintains specified VBR, VC, and leakage performance across -55 °C to +150 °C operating range.
What is the maximum clamping voltage of SMA5J7.5CHE3/61 under surge conditions?
The SMA5J7.5CHE3/61 exhibits a maximum clamping voltage (VC) of 12.9 V when subjected to a 100 A peak pulse current with a 10/1000 µs waveform. This value is measured at the device terminals under standardized test conditions and represents the upper voltage limit imposed on protected circuitry during worst-case transient events. The low VC relative to VWM (7.5 V) provides a 72 % clamping ratio, ensuring effective protection for 12 V nominal systems and compatible ICs with 16 V absolute maximum ratings.
How does the thermal resistance of SMA5J7.5CHE3/61 affect its surge capability?
The SMA5J7.5CHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. This value directly limits its ability to sustain repeated surges: higher ambient temperatures or insufficient copper area increase junction temperature rise, triggering derating per Figure 2 in the datasheet. For example, at 85 °C ambient, the SMA5J7.5CHE3/61 must be derated to ~70 % of its 500 W rating to avoid exceeding 150 °C TJ max.
What packaging format is used for SMA5J7.5CHE3/61?
SMA5J7.5CHE3/61 is supplied in 7-inch diameter plastic tape and reel format, with a base quantity of 1800 units per reel (package code 61). The tape conforms to EIA-481 standards and supports high-speed pick-and-place equipment. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification, while the "61" delivery mode identifier ensures compatibility with standard SMT feeders. This packaging enables efficient handling in high-volume automotive and industrial manufacturing lines.
