Product details
Overview
SMA5J6.0CA-M3/5A 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 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 48.5 A peak surge current - used in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the SMA5J6.0CA-M3/5A datasheet, SMA5J6.0CA-M3/5A pinout, SMA5J6.0CA-M3/5A application, or SMA5J6.0CA-M3/5A equivalent, key selection criteria include bidirectional clamping capability, 500 W surge rating, halogen-free RoHS-compliant M3 termination, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes.
Designed for surface-mount use on PCBs with minimum pad layout per DO-214AC, it sustains 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (260 °C reflow peak). The CA suffix confirms bidirectional polarity - no cathode marking - and electrical characteristics apply identically in both directions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse voltage before clamping begins; sets operating margin for protected line |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - defines reliable breakdown threshold range under standardized test conditions |
| VC @ IPPM | ≤10.3 V at 48.5 A - clamped voltage during 500 W transient, determining downstream IC stress level |
| PPPM | 500 W (10/1000 µs waveform) - peak surge energy handling capacity for lightning/inductive load events |
| ID @ VWM | ≤800 µA - leakage current at stand-off voltage, critical for low-power sensor or battery-backed circuits |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive or industrial enclosures |
| Package | SMA (DO-214AC) - standard SMT outline with 5.28 mm length, 4.93 mm width, 2.29 mm height, compatible with pick-and-place |
Pinout & Package
Two-terminal bidirectional device in SMA (DO-214AC) package; no polarity marking. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, with M3 suffix indicating halogen-free, RoHS-compliant construction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0CA-E3/5A | Same electrical specs; E3 suffix indicates RoHS-compliant commercial grade (non-halogen-free) | No difference in surge performance; not qualified for halogen-free manufacturing lines | Select E3 if halogen content is unrestricted and cost sensitivity outweighs green-material requirements |

FAQ
What is the clamping voltage of the SMA5J6.0CA-M3/5A at its rated peak pulse current?
The SMA5J6.0CA-M3/5A clamps to a maximum of 10.3 V at its rated peak pulse current of 48.5 A (10/1000 µs waveform). This value is measured under standardized test conditions with the device mounted on 5.0 mm × 5.0 mm copper pads per the Vishay datasheet. The clamping voltage directly determines the maximum stress imposed on downstream components during surge events, making it a critical parameter for circuit protection design using the SMA5J6.0CA-M3/5A.
Is the SMA5J6.0CA-M3/5A suitable for automotive applications?
Yes, the SMA5J6.0CA-M3/5A is suitable for automotive applications. While the base M3 variant is commercial-grade, it shares the same electrical and thermal specifications as AEC-Q101-qualified versions (e.g., SMA5J6.0CAHM3_A/I). Its 150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and robust surge handling make it widely deployed in cabin sensors, body control modules, and infotainment interfaces - provided system-level qualification is completed per OEM requirements for the SMA5J6.0CA-M3/5A.
What does the "CA" suffix indicate in SMA5J6.0CA-M3/5A?
The "CA" suffix in SMA5J6.0CA-M3/5A denotes a bidirectional configuration. Unlike unidirectional variants (e.g., SMA5J6.0A), this device provides symmetrical clamping in both polarities - meaning it protects AC-coupled lines or differential signals without regard to terminal orientation. No cathode band marking is present, and all electrical characteristics (VBR, VC, ID) apply identically in either direction, which is essential for protecting balanced interfaces like RS-485 or CAN using the SMA5J6.0CA-M3/5A.
How does the M3 suffix differ from E3 in SMA5J6.0CA-M3/5A?
The M3 suffix in SMA5J6.0CA-M3/5A specifies halogen-free, RoHS-compliant construction, whereas E3 indicates RoHS-compliant but not halogen-free. Both meet JESD 201 Class 2 whisker resistance and J-STD-002 solderability, but M3 complies with additional environmental standards such as IEC 61249-2-21 for bromine/chlorine content. This distinction matters for electronics destined for markets enforcing halogen restrictions - confirming that SMA5J6.0CA-M3/5A satisfies those requirements without sacrificing electrical performance.
What is the thermal resistance of the SMA5J6.0CA-M3/5A, and how does it affect layout?
The SMA5J6.0CA-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal PCB copper; increasing pad area or adding thermal vias reduces RθJA, improving surge endurance. Layout must follow the recommended DO-214AC mounting footprint to ensure the SMA5J6.0CA-M3/5A achieves its rated 500 W pulse power and avoids thermal runaway during repetitive transients.
