Product details
Overview
SMA5J5.0C-E3/5A from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on signal and power lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps to ≤9.2 V at 54.3 A peak pulse current - used in automotive sensor protection and industrial I/O interfaces.
For engineers reviewing the SMA5J5.0C-E3/5A datasheet, SMA5J5.0C-E3/5A pinout, SMA5J5.0C-E3/5A application, or SMA5J5.0C-E3/5A equivalent, key selection criteria include bi-directional surge capability, AEC-Q101 qualification, low clamping voltage under 10/1000 µs waveform, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with electrical characteristics valid across reverse and forward directions per ANSI/IEEE C62.35. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while low incremental surge resistance enables effective energy diversion during ESD or lightning-induced transients.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 (260 °C reflow peak). Thermal resistance is 80 °C/W junction-to-ambient (RθJA) and 25 °C/W junction-to-lead (RθJL), supporting reliable operation in compact PCB layouts with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - guaranteed breakdown range defining turn-on threshold |
| VC @ IPPM | ≤9.2 V at 54.3 A - clamping voltage under standardized 10/1000 µs surge, limiting downstream stress |
| PPPM | 500 W - peak pulse power handling capacity for transient suppression |
| ID @ VWM | ≤800 µA - low leakage current preserves signal integrity in standby |
| TJ max | +150 °C - enables use in under-hood automotive and high-temperature industrial environments |

FAQ
What does the "C" in SMA5J5.0C-E3/5A signify?
The "C" in SMA5J5.0C-E3/5A explicitly denotes a bi-directional configuration, meaning the device provides symmetrical transient suppression in both forward and reverse directions. This distinguishes it from uni-directional variants (e.g., SMA5J5.0A), and aligns with Vishay's naming convention where "CA" suffixes indicate bi-directional types. The SMA5J5.0C-E3/5A maintains identical VWM, VBR, and PPPM ratings in either polarity.
Is SMA5J5.0C-E3/5A AEC-Q101 qualified?
No - SMA5J5.0C-E3/5A carries the E3 suffix, indicating RoHS-compliant commercial-grade qualification. For AEC-Q101 qualification, the correct part is SMA5J5.0CAHE3/5A (HE3 suffix). The datasheet confirms AEC-Q101 applies only to HE3-suffixed variants, not E3-suffixed parts like SMA5J5.0C-E3/5A.
What is the clamping voltage of SMA5J5.0C-E3/5A under surge conditions?
The SMA5J5.0C-E3/5A clamps to a maximum of 9.2 V when subjected to its rated 10/1000 µs peak pulse current of 54.3 A. This VC value is measured at the device terminals under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during transient events.
Can SMA5J5.0C-E3/5A be used in place of SMA5J5.0A?
No - SMA5J5.0C-E3/5A is bi-directional, while SMA5J5.0A is uni-directional with a cathode band marking. Substituting them requires verifying circuit polarity and surge directionality. Uni-directional parts conduct forward surge current (IFSM = 40 A), whereas bi-directional types like SMA5J5.0C-E3/5A suppress equally in both directions but lack forward conduction rating.
What is the thermal resistance of SMA5J5.0C-E3/5A?
The SMA5J5.0C-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead resistance (RθJL) of 25 °C/W, measured on 0.2" × 0.2" copper pads per JEDEC standards. These values assume proper PCB layout and define safe power derating above 25 °C ambient.
