Product details
Overview
SMA5J8.0CA-E3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal or power lines. It features a 6.4 V minimum breakdown voltage (VBR), 8.0 V maximum stand-off voltage (VWM), 13.6 V clamping voltage (VC) at 36.8 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the SMA5J8.0CA-E3/61 datasheet, SMA5J8.0CA-E3/61 pinout, SMA5J8.0CA-E3/61 application, or SMA5J8.0CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, low incremental surge resistance, AEC-Q101 qualification eligibility (via HE3 suffix), 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 both polarities, with symmetrical electrical characteristics per direction. Its glass-passivated junction ensures stable breakdown behavior, and thermal resistance of 80 °C/W (junction-to-ambient) supports operation up to 150 °C junction temperature under defined PCB layout conditions.
The SMA5J8.0CA-E3/61 delivers 13.6 V clamping voltage at 36.8 A (10/1000 µs), with ≤1.0 µA reverse leakage at 8.0 V and fast response time typical of TVS diodes. It meets MSL level 1 per J-STD-020 and is rated for non-repetitive surge events only - not intended for continuous overvoltage regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum steady-state reverse voltage before significant leakage; defines safe operating window for protected circuit. |
| VBR (min) | 6.4 V - Minimum voltage at which avalanche conduction begins at 1 mA test current; ensures reliable triggering above system operating voltage. |
| VC @ IPPM | 13.6 V - Clamped voltage during 36.8 A 10/1000 µs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 500 W - Peak pulse power handling capacity; defines transient energy absorption limit under standardized waveform. |
| IPPM | 36.8 A - Peak surge current supported at VC; correlates directly with line impedance and surge source strength. |
| TJ max | 150 °C - Maximum junction temperature; sets thermal derating boundary for sustained surge repetition or ambient temperature rise. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional - no polarity marking; molded case meets UL 94 V-0; matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically in either polarity; no cathode band marking distinguishes bidirectional configuration. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J8.0CA-M3/61 | Halogen-free, RoHS-compliant variant with identical electrical specs and SMA package. | No functional difference; selected where halogen-free material compliance is mandated. | Choose when environmental compliance requires halogen-free construction without altering circuit design. |
| SMA6J8.0CA-E3/61 | 600 W peak pulse power rating (vs. 500 W), same VWM/VC, identical SMA package and pinout. | Higher energy handling enables longer surge duration tolerance or higher impedance line protection. | Prefer when system-level surge testing exceeds IEC 61000-4-5 Level 4 or requires margin beyond 500 W. |
Compared with SMA5J8.0CA-E3/61, the M3 variant offers identical protection performance with halogen-free materials, while the SMA6J8.0CA-E3/61 provides 20 % higher pulse power headroom - both retain the same footprint and clamping behavior, enabling drop-in replacement only where documentation explicitly confirms compatibility.

FAQ
What is the clamping voltage of the SMA5J8.0CA-E3/61 under a 10/1000 µs surge?
The SMA5J8.0CA-E3/61 has a maximum clamping voltage (VC) of 13.6 V at 36.8 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 88875), and defines the upper voltage limit imposed on protected circuitry during transient events. The SMA5J8.0CA-E3/61 maintains this clamping performance symmetrically in both directions due to its bidirectional construction.
Is the SMA5J8.0CA-E3/61 suitable for automotive applications?
Yes - the SMA5J8.0CA-E3/61 is RoHS-compliant and eligible for AEC-Q101 qualification when ordered with HE3 or HM3 suffixes. While the base SMA5J8.0CA-E3/61 itself is commercial-grade, its electrical and thermal specifications (TJ max = 150 °C, MSL Level 1, glass-passivated junction) align with automotive subsystem requirements such as body control modules and sensor interfaces. The SMA5J8.0CA-E3/61 is commonly deployed in non-safety-critical automotive functions where transient immunity to ISO 7637-2 pulses is required.
Does the SMA5J8.0CA-E3/61 have polarity markings?
No - the SMA5J8.0CA-E3/61 is a bidirectional TVS diode and carries no cathode band or polarity marking on the SMA (DO-214AC) package. Its symmetrical construction means both terminals perform identically regardless of applied voltage polarity. This distinguishes it from unidirectional variants like SMA5J8.0A-E3/61, which feature a visible cathode band. The SMA5J8.0CA-E3/61 must be mounted without orientation dependency.
What is the maximum reverse leakage current for the SMA5J8.0CA-E3/61 at its stand-off voltage?
The SMA5J8.0CA-E3/61 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated stand-off voltage (VWM) of 8.0 V, measured at TA = 25 °C. This low leakage ensures minimal power loss and avoids interference with high-impedance signal paths or precision reference circuits. The SMA5J8.0CA-E3/61 maintains this specification across its full operating temperature range, supporting reliable performance in battery-powered and low-quiescent-current designs.
Can the SMA5J8.0CA-E3/61 be used in place of a unidirectional TVS like SMA5J8.0A-E3/61?
No - the SMA5J8.0CA-E3/61 is bidirectional and lacks polarity marking, making it unsuitable as a direct replacement for unidirectional devices such as SMA5J8.0A-E3/61 in circuits requiring DC bias or asymmetric clamping. Using the SMA5J8.0CA-E3/61 in a unidirectional application may cause unintended conduction during normal forward-biased operation. Always verify circuit topology: SMA5J8.0CA-E3/61 is intended only for AC, floating, or dual-rail signal protection where symmetrical clamping is required.
