Product details
Overview
SMA5J15CAHE3/61 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 15 V stand-off voltage (VWM), 24.4 V maximum clamping voltage at 20.5 A peak pulse current, 500 W peak pulse power rating, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J15CAHE3/61 datasheet, SMA5J15CAHE3/61 pinout, SMA5J15CAHE3/61 application, or SMA5J15CAHE3/61 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (1.63×VWM), RoHS-compliant + AEC-Q101 qualified construction, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients exceeding its reverse stand-off voltage. Its bidirectional symmetry ensures identical clamping behavior in both polarities, with breakdown voltage (VBR) specified between 16.7 V and 18.5 V at 1 mA test current.
Thermal performance is defined by junction-to-ambient thermal resistance of 80 °C/W and maximum junction temperature of 150 °C. It meets J-STD-020 MSL Level 1 and withstands 260 °C reflow peak temperature, supporting robust manufacturing integration.

FAQ
What is the clamping voltage of the SMA5J15CAHE3/61 under a 10/1000 μs surge?
The SMA5J15CAHE3/61 clamps to a maximum of 24.4 V when subjected to its rated peak pulse current of 20.5 A under the standardized 10/1000 μs waveform. This value is measured at the device terminals with recommended 5.0 mm × 5.0 mm copper pads and represents the upper limit of voltage let-through during surge events, ensuring downstream components remain within safe operating limits.
Is SMA5J15CAHE3/61 suitable for automotive applications?
Yes, SMA5J15CAHE3/61 is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix. It supports operating junction temperatures from -55 °C to +150 °C, passes humidity and temperature cycling tests per AEC-Q101, and is rated for under-hood environments where transient immunity and long-term reliability are critical-making it appropriate for ECUs, body control modules, and ADAS power supplies.
How does the bidirectional configuration of SMA5J15CAHE3/61 affect its circuit implementation?
The SMA5J15CAHE3/61 has no polarity marking and exhibits symmetrical clamping in both directions, making it ideal for AC-coupled lines, differential buses (e.g., RS-485), or ungrounded DC rails where voltage reversals may occur. Unlike unidirectional TVS diodes, it eliminates the need for orientation verification during placement and ensures consistent protection regardless of signal polarity or ground reference shifts.
What is the maximum reverse leakage current of SMA5J15CAHE3/61 at its stand-off voltage?
The SMA5J15CAHE3/61 exhibits a maximum reverse leakage current (ID) of 1.0 μA when biased at its 15 V stand-off voltage (VWM) and tested at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes quiescent power draw in battery-powered systems without compromising surge response speed or clamping accuracy.
Can SMA5J15CAHE3/61 be used in parallel for higher surge current handling?
No-SMA5J15CAHE3/61 should not be paralleled without external current-balancing resistors due to parameter variation between units. Minor differences in breakdown voltage (16.7–18.5 V) cause uneven current sharing during transients, risking thermal runaway in the lower-VBR unit. For higher surge ratings, select a single higher-power device such as SMA6J15CAHE3/61 instead of paralleling SMA5J15CAHE3/61 units.
