Product details
Overview
SMA5J13AHE3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on DC power rails and signal lines. It features 13 V stand-off voltage (VWM), 21.5 V maximum clamping voltage (VC) at 23.3 A peak pulse current (IPPM), 500 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J13AHE3/61 datasheet, SMA5J13AHE3/61 pinout, SMA5J13AHE3/61 application, or SMA5J13AHE3/61 equivalent, key selection criteria include clamping performance under 10/1000 µs transients, unidirectional polarity with cathode band marking, thermal resistance (RθJA = 80 °C/W), and RoHS-compliant AEC-Q101 qualification for automotive electronics.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, triggering when reverse voltage exceeds 14.4–15.9 V breakdown (VBR) at 1 mA test current. Its low incremental surge resistance and fast response time enable effective suppression of ESD, lightning-induced surges, and inductive switching transients.
Designed for surface-mount placement on PCBs with minimum 0.2" × 0.2" copper pads per terminal, it supports automated assembly and meets J-STD-020 MSL Level 1 (260 °C peak reflow). The glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and long-term reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 14.4 V / 15.9 V - Breakdown voltage range at 1 mA, defining precise turn-on threshold |
| VC @ IPPM | 21.5 V - Clamped voltage during 23.3 A 10/1000 µs surge, limiting stress on downstream ICs |
| PPPM | 500 W - Peak pulse power handling capability under standardized surge waveform |
| IPPM | 23.3 A - Maximum non-repetitive surge current the device safely clamps without failure |
| TJ max | 150 °C - Maximum junction temperature, enabling operation in under-hood automotive environments |
| RθJA | 80 °C/W - Thermal resistance from junction to ambient, guiding heatsinking requirements on standard FR-4 |

FAQ
What is the breakdown voltage range of the SMA5J13AHE3/61?
The SMA5J13AHE3/61 has a guaranteed breakdown voltage (VBR) range of 14.4 V to 15.9 V at 1 mA test current, measured per ANSI/IEEE C62.35. This defines its precise conduction threshold under reverse bias and ensures consistent clamping behavior across production lots and temperature ranges.
Is the SMA5J13AHE3/61 suitable for automotive applications?
Yes, the SMA5J13AHE3/61 is AEC-Q101 qualified and explicitly designated for automotive use with suffix "HE3". It meets stringent reliability, temperature cycling, and surge endurance requirements for engine control, body electronics, and infotainment systems operating from -55 °C to +150 °C junction temperature.
What does the "HE3" suffix indicate in SMA5J13AHE3/61?
The "HE3" suffix in SMA5J13AHE3/61 denotes RoHS-compliant construction plus full AEC-Q101 qualification. It distinguishes this variant from commercial-grade "E3" parts and confirms compliance with automotive stress testing standards including HTRB, HTGB, and temperature cycling.
How is polarity identified on the SMA5J13AHE3/61 package?
The SMA5J13AHE3/61 uses a visible cathode band on the SMA (DO-214AC) case to mark the cathode terminal. During circuit layout, the banded end must connect to the protected line (e.g., 12 V rail), while the anode connects to ground - reversing polarity prevents proper clamping function.
What is the maximum clamping voltage of the SMA5J13AHE3/61 under surge conditions?
The SMA5J13AHE3/61 clamps to a maximum of 21.5 V when subjected to its rated 23.3 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed across temperature and ensures downstream ICs see controlled overvoltage stress during transient events.
