Product details
Overview
SMA5J7.0-E3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-214AC (SMA) package, designed for high-energy surge protection with 7.0 V standoff voltage, 7.78–8.60 V breakdown voltage at 10 mA, 12.0 V clamping voltage at 41.7 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 SMA5J7.0-E3/5A datasheet, SMA5J7.0-E3/5A pinout, SMA5J7.0-E3/5A application, or SMA5J7.0-E3/5A equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, RoHS-compliant matte tin plating, AEC-Q101 qualification (via HE3 suffix variants), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering fast response to transients induced by inductive load switching or ESD events. Its low incremental surge resistance and excellent clamping capability ensure stable voltage limiting during 10/1000 μs waveform surges up to 500 W.
The SMA5J7.0-E3/5A is rated for -55 °C to +150 °C operating junction temperature, exhibits 80 °C/W typical junction-to-ambient thermal resistance, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. Polarity is marked by cathode band; no marking applies to bi-directional variants.

FAQ
What is the maximum clamping voltage of the SMA5J7.0-E3/5A under peak pulse conditions?
The SMA5J7.0-E3/5A has a maximum clamping voltage (VC) of 12.0 V when subjected to its rated peak pulse current of 41.7 A using a 10/1000 μs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on protected circuits during transient events. The SMA5J7.0-E3/5A maintains this clamping performance across its specified operating temperature range and is validated per ANSI/IEEE C62.35 standards.
Is the SMA5J7.0-E3/5A RoHS compliant and lead-free?
Yes, the SMA5J7.0-E3/5A is RoHS compliant and lead-free, as confirmed by the "E3" suffix designation per Vishay's material categorization policy. The matte tin-plated leads meet J-STD-002 solderability requirements and pass JESD 201 Class 1A whisker testing. Full compliance documentation, including substance declarations and test reports, is available upon request for the SMA5J7.0-E3/5A.
Does the SMA5J7.0-E3/5A have AEC-Q101 qualification?
No, the SMA5J7.0-E3/5A is not AEC-Q101 qualified; that certification applies only to variants with the "HE3" suffix (e.g., SMA5J7.0AHE3/5A). The SMA5J7.0-E3/5A is commercial-grade and intended for industrial and consumer applications where automotive qualification is not required. For designs needing AEC-Q101 evidence, the SMA5J7.0-E3/5A must be replaced with its HE3 counterpart.
What is the thermal resistance and maximum junction temperature for the SMA5J7.0-E3/5A?
The SMA5J7.0-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" copper pads, and a maximum junction temperature (TJ max.) of +150 °C. These values are measured under standardized conditions and define safe operating limits for continuous and pulsed power dissipation. Derating curves in the SMA5J7.0-E3/5A datasheet guide thermal design above 25 °C ambient.
How does the SMA5J7.0-E3/5A differ from the SMA5J7.0A-E3/61 variant?
The SMA5J7.0-E3/5A and SMA5J7.0A-E3/61 share identical electrical, thermal, and mechanical specifications; the sole difference is packaging format - the SMA5J7.0-E3/5A uses a 13" diameter tape with 7500 units per reel, while the SMA5J7.0A-E3/61 uses a 7" tape with 1800 units. Both are RoHS-compliant commercial-grade parts. The SMA5J7.0-E3/5A is optimized for high-volume SMT line feeding.
