Product details
Overview
SMA5J5.0CAHE3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection. It features a 5.0 V stand-off voltage (VWM), 6.4–7.25 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps transients to ≤9.2 V at 54.3 A IPPM - used to protect automotive sensor signal lines, USB interfaces, and industrial I/O ports against ESD and inductive switching spikes.
For engineers reviewing the SMA5J5.0CAHE3/61 datasheet, SMA5J5.0CAHE3/61 pinout, SMA5J5.0CAHE3/61 application, or SMA5J5.0CAHE3/61 equivalent, key selection criteria include bidirectional polarity, AEC-Q101 qualification, 150 °C junction temperature rating, low clamping voltage under 10/1000 μs surge, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. Its glass-passivated junction enables fast response (<1 ns) and stable clamping across -55 °C to +150 °C operating range, while meeting MSL Level 1 reflow requirements up to 260 °C peak.
The SMA5J5.0CAHE3/61 delivers 500 W peak pulse power under standardized 10/1000 μs waveform conditions, with thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), enabling robust surge handling on standard PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse voltage before clamping begins; defines safe operating window for protected circuitry |
| VBR min/max | 6.4 V / 7.25 V - guaranteed breakdown range at 10 mA test current; ensures reliable turn-on during transients |
| VC @ IPPM | 9.2 V - clamping voltage at 54.3 A peak pulse current; limits stress on downstream ICs like microcontrollers or transceivers |
| PPPM | 500 W - peak pulse power dissipation capability under 10/1000 μs waveform; supports high-energy surge immunity |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive or industrial environments |
| Package | SMA (DO-214AC) - surface-mount package with 0.208" × 0.157" footprint; compatible with standard pick-and-place equipment |
| AEC-Q101 | Qualified - certified for automotive-grade reliability per JESD22-A108; suitable for safety-critical vehicle subsystems |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J5.0CA-M3/61 | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification | No functional difference; selected where halogen-free materials are mandated in final assembly | Choose SMA5J5.0CAHE3/61 for standard RoHS compliance; choose SMA5J5.0CA-M3/61 only if halogen-free requirement applies |
| SMA6J5.0CAHE3/61 | 600 W PPPM rating (vs. 500 W), same VWM/VBR/VC, identical package and AEC-Q101 qualification | Higher surge margin for designs facing more severe ISO 16750-2 or IEC 61000-4-5 threats | Select SMA6J5.0CAHE3/61 when system-level testing requires >500 W surge headroom; otherwise SMA5J5.0CAHE3/61 suffices |
Compared with SMA5J5.0CA-M3/61, the SMA5J5.0CAHE3/61 offers identical protection performance with standard RoHS compliance; versus SMA6J5.0CAHE3/61, it trades 100 W lower peak power for cost and footprint optimization where 500 W meets design margin requirements.

FAQ
What is the clamping voltage of the SMA5J5.0CAHE3/61 under maximum surge conditions?
The SMA5J5.0CAHE3/61 clamps to a maximum of 9.2 V when subjected to its rated peak pulse current of 54.3 A under the standard 10/1000 μs waveform. This value is measured at the device terminals with specified mounting conditions (0.2" × 0.2" copper pads), and represents the upper limit of voltage imposed on protected circuitry during worst-case transients.
Is the SMA5J5.0CAHE3/61 suitable for automotive applications?
Yes, the SMA5J5.0CAHE3/61 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and operation from −55 °C to +150 °C - all validated per automotive reliability standards. It is commonly deployed in ADAS sensors, body control modules, and infotainment interfaces.
How does the bidirectional configuration of SMA5J5.0CAHE3/61 affect PCB layout?
The SMA5J5.0CAHE3/61 has no polarity marking and functions identically in either orientation, simplifying PCB layout and eliminating risk of incorrect placement. This symmetry allows direct placement across differential pairs or AC-coupled lines without directional verification, reducing assembly errors and supporting automated optical inspection.
What is the maximum leakage current of SMA5J5.0CAHE3/61 at its stand-off voltage?
At the 5.0 V stand-off voltage (VWM) and 25 °C ambient temperature, the SMA5J5.0CAHE3/61 exhibits a maximum reverse leakage current of 800 μA. This low leakage ensures minimal impact on power budget and signal integrity in always-on or battery-powered systems.
Does SMA5J5.0CAHE3/61 require derating at elevated temperatures?
Yes, the SMA5J5.0CAHE3/61 must be derated above 25 °C ambient per Figure 2 in the datasheet. Its peak pulse power capability decreases linearly to ~50 % at 125 °C junction temperature. Designers must calculate actual TJ using RθJA (80 °C/W) and ensure thermal design keeps junction temperature within the −55 °C to +150 °C limit.
