Product details
Overview
SMA5J5.0CAHE3_A/I 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 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps transients to ≤9.2 V at 54.3 A IPPM - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line circuits.
For engineers reviewing the SMA5J5.0CAHE3_A/I datasheet, SMA5J5.0CAHE3_A/I pinout, SMA5J5.0CAHE3_A/I application, or SMA5J5.0CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, 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 silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bidirectional construction. Its 10/1000 μs waveform response enables suppression of lightning-induced surges and inductive switching transients without degradation under repeated stress.
Thermal performance is defined by RθJA = 80 °C/W and RθJL = 25 °C/W, supporting operation from –55 °C to +150 °C. The SMA (DO-214AC) package meets UL 94 V-0 flammability rating and J-STD-020 MSL Level 1 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins; sets threshold for protection activation in bidirectional mode. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - guaranteed avalanche onset range ensures consistent turn-on across production lots. |
| VC @ IPPM | 9.2 V at 54.3 A - clamping voltage during 500 W surge defines worst-case overvoltage seen by downstream ICs. |
| PPPM | 500 W - peak pulse power handling per 10/1000 μs waveform; determines survivability against IEC 61000-4-5 Level 4 surges. |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive and high-ambient industrial environments. |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H); matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; current flows bidirectionally during overvoltage events - no cathode band marking required. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMA package | Enables compact PCB layout in space-constrained modules such as automotive ECUs and IoT edge nodes. |
| Glass-passivated junction | Ensures stable VBR and leakage performance over time and temperature, critical for long-life industrial deployments. |
| MSL Level 1 rating | Supports single-reflow assembly without moisture sensitivity concerns - eliminates bake requirements pre-SMT. |
| 500 W peak pulse power | Provides robust immunity to IEC 61000-4-5 4 kV/2 Ω surge tests on 24 V supply rails and CAN/LIN bus lines. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt surge energy before reaching ADC front-end or signal conditioner. Use Value: Limits transient voltage to ≤9.2 V, preserving 12-bit ADC accuracy and preventing latch-up in microcontroller input pins. |
Use Scenario: Shielding 24 V digital input channels in programmable logic controllers from field-wiring induced surges and ground bounce. IC Role / Device Role / Timing Role: Standoff-rated TVS placed between terminal block and optocoupler input, absorbing repetitive 500 W transients without degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J5.0CAHM3_A/I | Halogen-free variant with identical electrical specs and AEC-Q101 qualification; same thermal and surge ratings. | No difference in circuit design or layout; substitution requires only material compliance verification (RoHS + halogen-free). | Select when halogen-free bill-of-materials is mandated by OEM or regional environmental regulations. |
| SMCJ5.0CAHE3_A/I | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package; higher RθJA (50 °C/W vs. 80 °C/W) and 1500 W PPPM rating. | Better thermal dissipation and higher surge capacity; requires larger PCB footprint and different pad layout. | Choose for higher-reliability industrial systems where 1500 W surge margin or extended thermal lifetime is required. |
Compared with SMA5J5.0CAHE3_A/I, the SMA5J5.0CAHM3_A/I offers identical protection performance with halogen-free construction, while the SMCJ5.0CAHE3_A/I delivers triple the pulse power rating in a larger package - enabling longer surge endurance in thermally constrained designs without changing clamping behavior.

FAQ
What is the polarity configuration of SMA5J5.0CAHE3_A/I?
The SMA5J5.0CAHE3_A/I is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants, it has no cathode band marking and functions identically across both terminals - essential for protecting AC-coupled or differential signal lines where polarity is undefined.
Is SMA5J5.0CAHE3_A/I qualified for automotive applications?
Yes, SMA5J5.0CAHE3_A/I is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114. This certification confirms its suitability for under-hood and chassis-mounted automotive electronics where reliability under thermal and mechanical stress is mandatory.
What is the maximum clamping voltage for SMA5J5.0CAHE3_A/I at rated surge current?
The SMA5J5.0CAHE3_A/I clamps to a maximum of 9.2 V at its rated peak pulse current (IPPM) of 54.3 A, measured under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-rated surge event.
Does SMA5J5.0CAHE3_A/I require special PCB layout considerations?
Yes - for optimal thermal and surge performance, SMA5J5.0CAHE3_A/I must be mounted on minimum recommended 5.0 mm × 5.0 mm copper pads per terminal, per Vishay's datasheet fig. 2. Smaller pads reduce heat dissipation and increase risk of solder joint failure during repetitive surges.
How does the HE3 suffix affect the specifications of SMA5J5.0CAHE3_A/I?
The HE3 suffix denotes RoHS-compliant construction with AEC-Q101 qualification - it does not alter electrical parameters. SMA5J5.0CAHE3_A/I retains identical VWM (5.0 V), VBR (6.4–7.07 V), VC (9.2 V), and PPPM (500 W) as the base SMA5J5.0CA, while adding automotive-grade reliability validation and lead-free plating.
