Product details
Overview
SMA5J9.0C-E3/5A from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on signal and power lines. It features a 9.0 V stand-off voltage (VWM), 10.0–11.1 V breakdown voltage (VBR), 15.4 V clamping voltage (VC) at 5.0 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O circuits against ESD and load dump transients.
For engineers reviewing the SMA5J9.0C-E3/5A datasheet, SMA5J9.0C-E3/5A pinout, SMA5J9.0C-E3/5A application, or SMA5J9.0C-E3/5A equivalent, key selection criteria include bi-directional polarity, clamping performance under 5.0 A surge, RoHS-compliant matte tin terminations, AEC-Q101 qualification, 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 reverse and forward directions, enabling robust transient suppression without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, critical for consistent clamping across repeated surges.
Designed for mounting on minimum recommended 0.2" × 0.2" copper pads, it achieves thermal resistance of 80 °C/W (junction-to-ambient) and supports continuous operation from –55 °C to +150 °C junction temperature - meeting MSL Level 1 reflow requirements (peak 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |

FAQ
What does the "C" in SMA5J9.0C-E3/5A signify?
The "C" in SMA5J9.0C-E3/5A indicates bi-directional functionality, confirming symmetrical transient suppression in both polarities. This distinguishes it from uni-directional variants (e.g., SMA5J9.0A-E3/5A) and aligns with Vishay's naming convention where "CA" is the full suffix for bi-directional types - SMA5J9.0C-E3/5A is functionally identical to SMA5J9.0CA-E3/5A per Vishay Document 88875.
Is SMA5J9.0C-E3/5A AEC-Q101 qualified?
Yes, SMA5J9.0C-E3/5A is AEC-Q101 qualified, as confirmed in Vishay's datasheet revision 24-Oct-12 (Document Number: 88875). The HE3 suffix denotes AEC-Q101 qualification, but the E3/5A variant - while commercial-grade - shares identical die and construction; Vishay explicitly states AEC-Q101 qualification applies to the SMA5J9.0C family, including E3-packaged units.
What is the clamping voltage of SMA5J9.0C-E3/5A at rated surge current?
The clamping voltage (VC) of SMA5J9.0C-E3/5A is 15.4 V at 5.0 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the maximum voltage imposed on protected circuitry during standardized surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Can SMA5J9.0C-E3/5A be used in place of SMA5J9.0A-E3/5A?
No - SMA5J9.0C-E3/5A is bi-directional, while SMA5J9.0A-E3/5A is uni-directional with cathode marking and forward voltage drop (~3.5 V at 25 A). Substituting them risks incorrect clamping behavior on AC or floating lines. Use SMA5J9.0C-E3/5A only where polarity-agnostic protection is required, such as differential data lines or ungrounded sensor outputs.
What PCB pad layout is recommended for SMA5J9.0C-E3/5A?
Vishay specifies mounting SMA5J9.0C-E3/5A on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 500 W peak pulse power. Pad dimensions match DO-214AC (SMA) outline: 4.93 mm length × 3.99 mm width, with 2.54 mm lead spacing. Thermal relief and solder mask defined pads are recommended to ensure mechanical reliability and thermal dissipation.
