Product details
Overview
SMA5J10CAHE3/61 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 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V clamping voltage at 29.4 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 μs waveform - used to safeguard automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMA5J10CAHE3/61 datasheet, SMA5J10CAHE3/61 pinout, SMA5J10CAHE3/61 application, or SMA5J10CAHE3/61 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low incremental surge resistance, and compatibility with automated SMT assembly on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 μA at VWM), while the low RθJA of 80 °C/W supports thermal reliability under repetitive surge conditions.
The device complies with ANSI/IEEE C62.35 for transient suppression and meets JESD201 Class 2 whisker resistance. Its MSL Level 1 rating (260 °C peak reflow) and matte tin-plated leads ensure robust solderability per J-STD-002 and JESD22-B102 - critical for automotive-grade production environments.

FAQ
What is the clamping voltage of the SMA5J10CAHE3/61 at its rated peak pulse current?
The SMA5J10CAHE3/61 has a maximum clamping voltage (VC) of 17.0 V when subjected to its peak pulse current (IPPM) of 29.4 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream circuitry remains below safe voltage thresholds during standardized surge events. The SMA5J10CAHE3/61 maintains this clamping performance across its full operating temperature range of -55 °C to +150 °C.
Is the SMA5J10CAHE3/61 suitable for automotive applications?
Yes, the SMA5J10CAHE3/61 is AEC-Q101 qualified and specifically intended for automotive use. Its RoHS-compliant construction, MSL Level 1 reflow rating, and validated performance across -55 °C to +150 °C junction temperature make it appropriate for engine control units, ADAS camera modules, and body electronics. The SMA5J10CAHE3/61 meets automotive surge immunity standards including ISO 7637-2 and ISO 16750-2.
Does the SMA5J10CAHE3/61 have polarity markings?
No, the SMA5J10CAHE3/61 does not have polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., SMA5J10A), it lacks a cathode band and functions identically in both directions - simplifying layout and eliminating orientation errors during automated placement. This symmetry is confirmed in Vishay's datasheet Document Number 88875, Section "Polarity".
What is the thermal resistance of the SMA5J10CAHE3/61?
The SMA5J10CAHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Its junction-to-lead resistance (RθJL) is 25 °C/W. These values are measured under standardized JEDEC conditions and enable accurate thermal modeling for sustained surge duty cycles in enclosed industrial environments.
How does the SMA5J10CAHE3/61 differ from the unidirectional SMA5J10A?
The SMA5J10CAHE3/61 is bidirectional with symmetrical clamping in both polarities and no cathode marking, whereas the SMA5J10A is unidirectional with a cathode band and forward conduction capability. Electrically, SMA5J10CAHE3/61 has identical VWM (10 V), VBR (11.1–12.3 V), and VC (17.0 V) but omits IFSM (40 A) since it lacks forward rectification. Both share the same 500 W PPPM rating and SMA package.
