Product details
Overview
SMA5J8.0-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-214AC (SMA) package, designed for high-energy surge protection on power and signal lines. It features a 8.0 V stand-off voltage (VWM), 8.89–9.83 V breakdown voltage (VBR) at 1 mA, 13.6 V clamping voltage (VC) at 36.8 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMA5J8.0-E3/61 datasheet, SMA5J8.0-E3/61 pinout, SMA5J8.0-E3/61 application, or SMA5J8.0-E3/61 equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, RoHS-compliant matte tin-plated leads, AEC-Q101 qualification (via HE3 variant), 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 optimized for transient suppression in DC power rails and low-voltage signal paths. Its glass-passivated junction ensures stable breakdown behavior, while low incremental surge resistance enables effective clamping during fast-rising ESD or inductive-switching transients.
The SMA5J8.0-E3/61 delivers 500 W peak pulse power handling under standardized 10/1000 µs waveform conditions, with thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), supporting reliable operation up to 150 °C junction temperature in compact surface-mount layouts.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges above 13.6 V. Use Value: Prevents damage to downstream LDOs and microcontrollers by limiting transient voltage to safe levels within 1 ns response time. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors connected to PLC I/O modules. IC Role / Device Role / Timing Role: Standoff protection on 0–10 V or 4–20 mA signal lines against field-induced EFT bursts. Use Value: Maintains signal integrity with only 1.0 µA leakage at 8.0 V, avoiding offset errors in precision measurement circuits. |
| Consumer Power Adapter Input Stage | Telecom DC Feeder Line Protection |
Use Scenario: Secondary-side surge suppression in AC/DC adapters powering USB-C PD devices. IC Role / Device Role / Timing Role: Clamping component across +5 V output and GND to absorb coupling noise from primary-side switching.

IC Role / Device Role / Timing Role: Unidirectional TVS referenced to negative rail to suppress positive-going surges induced by lightning or hot-swap events. Use Value: 13.6 V clamping ensures protected circuitry remains below absolute maximum ratings even during worst-case 10/1000 µs transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J8.0AHE3/61 | AEC-Q101 qualified; identical electrical specs; HE3 suffix denotes automotive-grade whisker testing (JESD201 Class 2) | Required for automotive under-hood modules where qualification traceability is mandatory | Select when automotive PPAP compliance or extended temperature cycling validation is required |
| P6SMB8.0A-E3/52 | Same DO-214AA package; 500 W rating; slightly higher VBR (9.17–10.1 V) and VC (13.5 V); lower IPPM (37.0 A) | Compatible in space-constrained designs but may exhibit earlier clamping onset due to higher VBR | Choose if legacy P6SMB footprint reuse is needed and minor VBR shift is acceptable |
Compared with SMA5J8.0AHE3/61, the SMA5J8.0-E3/61 lacks AEC-Q101 certification but offers identical surge performance and commercial-grade cost; versus P6SMB8.0A-E3/52, it provides tighter VBR tolerance and same clamping voltage in a marginally larger DO-214AC body, enabling higher thermal dissipation in sustained surge scenarios.

FAQ
What is the maximum clamping voltage of the SMA5J8.0-E3/61 under rated surge conditions?
The SMA5J8.0-E3/61 has a maximum clamping voltage (VC) of 13.6 V when subjected to its rated peak pulse current of 36.8 A using the standard 10/1000 µs waveform. This value is measured at the device terminals under specified test conditions and defines the upper voltage limit imposed on protected circuitry during a full 500 W transient event. The SMA5J8.0-E3/61 maintains this clamping performance across its operational temperature range.
Is the SMA5J8.0-E3/61 suitable for automotive applications?
The SMA5J8.0-E3/61 is RoHS-compliant and manufactured to Vishay's commercial-grade specifications, but it is not AEC-Q101 qualified. For automotive applications requiring formal qualification, the SMA5J8.0AHE3/61 variant - which shares identical electrical parameters and adds AEC-Q101 certification - should be selected. The SMA5J8.0-E3/61 may be used in non-safety-critical automotive subsystems where qualification is not mandated, but system-level validation remains the customer's responsibility.
What does the "E3/61" suffix indicate in SMA5J8.0-E3/61?
The "E3" suffix denotes RoHS-compliant, commercial-grade termination meeting JESD201 Class 1A whisker resistance requirements, while "/61" specifies packaging in 7-inch diameter plastic tape and reel with a base quantity of 1800 units. This ordering code confirms the part is supplied in standard SMT-compatible format with matte tin-plated leads and full traceability per Vishay's material categorization policy.
How does the SMA5J8.0-E3/61 compare to bi-directional TVS diodes like SMA5J8.0CA?
The SMA5J8.0-E3/61 is unidirectional and intended for DC line protection where polarity is fixed, whereas SMA5J8.0CA is bi-directional and suited for AC or floating signal lines. The unidirectional SMA5J8.0-E3/61 offers lower leakage (1.0 µA vs. 800 µA for the CA version at VWM) and higher surge current rating (36.8 A vs. 50 A for SMA5J8.0CA), making it preferable for low-leakage DC rail protection. The SMA5J8.0-E3/61 also features a cathode band marking, unlike the unmarked bi-directional variant.
What is the recommended PCB pad layout for optimal thermal and surge performance of the SMA5J8.0-E3/61?
Vishay specifies mounting the SMA5J8.0-E3/61 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 500 W pulse power dissipation and thermal resistance of 80 °C/W. Minimum pad dimensions follow DO-214AC outline drawings, with thermal vias recommended beneath pads for enhanced heat spreading. The SMA5J8.0-E3/61 must be placed outside high-impedance analog traces to avoid coupling noise during clamping events.
