Product details
Overview
SMA5J9.0-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-214AC (SMA) package, designed for high-energy surge protection with 9.0 V stand-off voltage, 10.0–11.1 V breakdown range, 15.4 V clamping voltage at 5.0 A peak pulse current, and 500 W peak pulse power rating. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMA5J9.0-E3/61 datasheet, SMA5J9.0-E3/61 pinout, SMA5J9.0-E3/61 application, or SMA5J9.0-E3/61 equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, RoHS-compliant matte tin plating, MSL Level 1 qualification, and AEC-Q101 eligibility for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode optimized for transient suppression using a glass-passivated junction. Its 10/1000 μs waveform response delivers 500 W peak pulse power dissipation with low incremental surge resistance and fast clamping action-critical for protecting sensitive downstream circuitry from inductive switching spikes and ESD events.
Designed for surface-mount assembly on 0.2" × 0.2" copper pads per terminal, it exhibits thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), enabling reliable operation across -55 °C to +150 °C ambient conditions without derating below 25 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J9.0AHE3/61 | AEC-Q101 qualified; identical electrical specs; HE3 suffix denotes enhanced whisker resistance (JESD 201 Class 2) | Required for automotive production programs needing full qualification documentation and extended reliability testing | Select when automotive OEM compliance is mandatory; otherwise SMA5J9.0-E3/61 suffices for commercial/industrial use |
| SMCJ9.0A-E3/73 | Higher 1500 W PPPM rating; larger DO-214AB (SMC) package; same VWM/VBR/VC values | Better suited for systems requiring higher surge margin or longer pulse duration immunity | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4; requires PCB footprint change |
Compared with SMA5J9.0AHE3/61 and SMCJ9.0A-E3/73, the SMA5J9.0-E3/61 offers optimal cost-performance balance for non-automotive industrial and consumer applications where 500 W surge immunity and DO-214AC footprint constraints are primary design drivers.

FAQ
What is the maximum clamping voltage of the SMA5J9.0-E3/61 under standard surge conditions?
The SMA5J9.0-E3/61 has a maximum clamping voltage (VC) of 15.4 V when subjected to a 10/1000 μs waveform at 5.0 A peak pulse current. This value is measured per JEDEC/ANSI standards and ensures protected circuit nodes remain below critical voltage thresholds during transient events. The SMA5J9.0-E3/61 maintains this clamping performance across its full operating temperature range.
Is the SMA5J9.0-E3/61 suitable for automotive applications?
The SMA5J9.0-E3/61 is RoHS-compliant and built on Vishay's AEC-Q101-qualified platform, but the E3 suffix denotes commercial-grade qualification. For production automotive use, the SMA5J9.0AHE3/61 variant is required-it carries full AEC-Q101 certification documentation. The SMA5J9.0-E3/61 may be used in automotive prototyping or non-safety-critical subsystems where full qualification is not mandated.
What does the "-E3/61" suffix indicate in SMA5J9.0-E3/61?
The "E3" suffix indicates RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability requirements, plus JESD 201 Class 1A whisker resistance. The "/61" denotes packaging in 7-inch diameter plastic tape and reel, with a base quantity of 1800 units per reel. This format supports automated SMT assembly lines.
How does the SMA5J9.0-E3/61 compare to bi-directional TVS diodes like SMA5J9.0CA?
The SMA5J9.0-E3/61 is unidirectional and features a cathode band for polarity identification, whereas SMA5J9.0CA is bi-directional with no marking. Electrically, the CA version has symmetric breakdown in both directions and double the ID limit for VWM ≤10 V. The SMA5J9.0-E3/61 is preferred for DC power rail protection where polarity is fixed and lower leakage is needed.
What thermal derating applies to the SMA5J9.0-E3/61 above 25 °C ambient?
The SMA5J9.0-E3/61 follows Vishay's standard derating curve: peak pulse power decreases linearly above 25 °C ambient, reaching ~75 % of 500 W at 75 °C and ~50 % at 125 °C. Derating is based on junction-to-ambient thermal resistance of 80 °C/W and assumes mounting on 0.2" × 0.2" copper pads. Full derating data is provided in Figure 2 of the official datasheet.
