Product details
Overview
SMA5J36CAHE3/5A from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 58.1 V clamping voltage (VC) at 8.6 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 SMA5J36CAHE3/5A datasheet, SMA5J36CAHE3/5A pinout, SMA5J36CAHE3/5A application, or SMA5J36CAHE3/5A equivalent, key selection criteria include bidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped shunt protector, responding within picoseconds to transients exceeding its VWM of 36 V. Its bidirectional symmetry ensures identical clamping behavior in both polarities, with guaranteed VBR min/max of 40.0 V / 44.2 V at 1 mA test current and maximum ID leakage of 1.0 µA at VWM.
Thermally, it exhibits RθJA = 80 °C/W and RθJL = 25 °C/W, enabling reliable operation up to TJ = 150 °C when mounted per recommended pad layout. The glass-passivated junction and MSL Level 1 rating support reflow compatibility at 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA - defines precise voltage threshold where avalanche conduction begins |
| VC @ IPPM | 58.1 V at 8.6 A - clamped voltage during 10/1000 µs surge, limiting stress on downstream ICs |
| PPPM | 500 W - peak transient energy absorption capability under standardized waveform |

| Polarity | Bidirectional - provides symmetrical protection without polarity sensitivity on AC or floating lines |
| Package | SMA (DO-214AC) - surface-mount outline with 5.28 mm length, 4.50 mm width, 2.29 mm height |
Pinout & Package
SMA5J36CAHE3/5A uses the standard SMA (DO-214AC) package: molded epoxy case with matte tin-plated leads, no polarity marking (bidirectional type), and MSL Level 1 moisture sensitivity. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per Vishay's thermal derating guidelines.

FAQ
What is the clamping voltage of SMA5J36CAHE3/5A at its rated peak pulse current?
The SMA5J36CAHE3/5A has a maximum clamping voltage (VC) of 58.1 V when subjected to its specified peak pulse current (IPPM) of 8.6 A using the 10/1000 µs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and ensures predictable voltage limiting during surge events. The clamping performance is consistent in both directions due to its bidirectional design, making SMA5J36CAHE3/5A suitable for protecting balanced or floating signal lines.
Is SMA5J36CAHE3/5A qualified for automotive applications?
Yes, SMA5J36CAHE3/5A is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. This certification confirms compliance with stress tests including high-temperature reverse bias, temperature cycling, and ESD robustness required for automotive electronic modules. The device is rated for operation from –55 °C to +150 °C junction temperature, supporting under-hood and cabin applications. SMA5J36CAHE3/5A meets these requirements without derating when mounted per Vishay's recommended pad layout.
What does the "CA" suffix mean in SMA5J36CAHE3/5A?
The "CA" suffix in SMA5J36CAHE3/5A denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both polarities, with identical VBR, VC, and IPPM characteristics regardless of voltage polarity applied. Unlike unidirectional variants (e.g., SMA5J36A), SMA5J36CAHE3/5A has no cathode marking and is used where AC signals, floating grounds, or polarity-agnostic protection are required. This makes SMA5J36CAHE3/5A ideal for differential buses and transformer-coupled interfaces.
What is the maximum leakage current of SMA5J36CAHE3/5A at its stand-off voltage?
The maximum reverse leakage current (ID) of SMA5J36CAHE3/5A is 1.0 µA when biased at its stand-off voltage (VWM) of 36 V and tested at TA = 25 °C. This low leakage ensures minimal power loss and signal interference in always-on or battery-powered systems. Leakage remains within specification across the full operating temperature range, and the device maintains this performance due to its glass-passivated junction structure, which prevents parameter drift under humidity or thermal stress.
How is SMA5J36CAHE3/5A packaged for automated assembly?
SMA5J36CAHE3/5A is supplied in 13-inch plastic tape and reel packaging (package code "5A"), containing 7500 units per reel. It complies with J-STD-002 and JESD 22-B102 for solderability and meets JESD 201 Class 2 whisker resistance. The SMA (DO-214AC) package supports high-speed pick-and-place operations, and its MSL Level 1 rating allows exposure to ambient conditions without baking prior to reflow. The matte tin-plated leads ensure consistent wetting during lead-free reflow profiles up to 260 °C peak.
