Product details
Overview
SMA5J9.0CAHE3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 9.0 V stand-off voltage (VWM), 10.0–11.1 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), clamping voltage of 15.4 V at 32.5 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J9.0CAHE3/61 datasheet, SMA5J9.0CAHE3/61 pinout, SMA5J9.0CAHE3/61 application, or SMA5J9.0CAHE3/61 equivalent, key selection criteria include bidirectional clamping capability, low incremental surge resistance, MSL Level 1 moisture sensitivity, 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 CA construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns) to transients induced by ESD, lightning, or inductive switching.
The device delivers 500 W peak pulse power under standardized 10/1000 µs waveform conditions when mounted per recommended pad layout, with thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for protected circuitry. |
| VBR (min/max) | 10.0 V / 11.1 V at 1 mA - Confirmed breakdown threshold range ensuring predictable turn-on during overvoltage events. |
| VC @ IPPM | 15.4 V at 32.5 A - Clamped voltage during 500 W surge; determines maximum stress imposed on downstream components. |
| PPPM | 500 W - Peak pulse power handling (10/1000 µs waveform); enables robust protection against IEC 61000-4-5 Level 4 surges. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial environments. |
| Package | SMA (DO-214AC) - Surface-mount package with 5.28 mm × 4.50 mm footprint, compatible with standard reflow profiles and J-STD-020 MSL Level 1. |
Pinout & Package
SMA (DO-214AC) package: molded plastic case with matte tin-plated leads, UL 94 V-0 rated, no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; bidirectional clamping allows connection across any two points needing surge suppression without orientation constraints. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring long-term reliability under thermal cycling and vibration. |
| Glass passivated junction | Ensures stable reverse leakage (<1.0 µA at VWM) and consistent VBR over time and temperature, critical for precision protection circuits. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD), improving protection margin for sensitive ICs like CAN transceivers or ADC front-ends. |
| MSL Level 1 (260 °C peak) | Enables single-pass lead-free reflow without baking or special handling, reducing manufacturing complexity and cost in high-volume SMT lines. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting LIN bus and analog sensor inputs (e.g., temperature, pressure) in engine compartments exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt surge energy before reaching MCU or signal conditioner. Use Value: Maintains signal integrity under 500 W transients while operating reliably at 150 °C ambient, meeting OEM AEC-Q100 stress requirements. |
Use Scenario: Safeguarding 24 V DC digital input modules in factory automation systems subject to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp on field-side terminals, coordinated with upstream fusing and filtering for Class III surge immunity. Use Value: Delivers 15.4 V clamping at 32.5 A, limiting stress on optocoupler input stages and preventing false triggering in noisy industrial environments. |
| Telecom Line Interface | Consumer USB/Display Port ESD Protection |
Use Scenario: Transient suppression on RS-485/RS-232 data lines in base station backhaul equipment subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Fast-response bidirectional TVS placed adjacent to line driver/receiver ICs to absorb common-mode and differential-mode transients. Use Value: Sub-1 ns response time and symmetrical VBR ensure balanced clamping across differential pairs, preserving signal timing and eye diagram integrity. |
Use Scenario: Board-level ESD protection for USB 2.0 and DisplayPort auxiliary channels in laptops and docking stations. IC Role / Device Role / Timing Role: Secondary protection stage after integrated ESD arrays, handling higher-energy discharges exceeding IEC 61000-4-2 ±15 kV contact. Use Value: 500 W rating and low capacitance (typ. <100 pF at 0 V) prevent signal degradation while providing fail-safe clamping during system-level ESD events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J9.0CA-M3/61 | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification; same SMA package and thermal performance. | No functional difference; selected where halogen-free material compliance is mandated by end-equipment environmental policy. | Direct substitution if halogen-free requirement applies; no layout or test changes needed. |
| SMA6J9.0CAHE3/61 | 600 W peak pulse power (vs. 500 W); otherwise identical VWM, VBR, VC, and package; higher IPPM (36.7 A vs. 32.5 A). | Supports higher-energy surge standards (e.g., IEC 61000-4-5 Level 5) or longer-duration transients where 500 W margin is insufficient. | Select when design requires >500 W surge headroom; verify PCB thermal relief and pad layout support for increased dissipation. |
Compared with SMA5J9.0CAHE3/61, the SMA5J9.0CA-M3/61 offers identical protection performance with halogen-free materials, while the SMA6J9.0CAHE3/61 provides 20 % higher pulse power handling-enabling more robust surge margin without changing board layout or mounting method.

FAQ
What does the "CA" suffix indicate in SMA5J9.0CAHE3/61?
The "CA" suffix denotes a bidirectional configuration, meaning the SMA5J9.0CAHE3/61 provides symmetrical clamping in both forward and reverse directions. This eliminates polarity concerns during placement and makes it ideal for protecting AC-coupled signals, differential buses like RS-485, or ungrounded power rails where voltage reversals may occur.
Is SMA5J9.0CAHE3/61 suitable for automotive applications?
Yes, SMA5J9.0CAHE3/61 is AEC-Q101 qualified and carries the "HE3" suffix indicating RoHS-compliance and automotive-grade reliability. It operates from −55 °C to +150 °C, withstands mechanical shock and thermal cycling, and meets stringent automotive surge immunity requirements such as ISO 7637-2 and IEC 61000-4-5 when applied per recommended layout.
What is the clamping voltage of SMA5J9.0CAHE3/61 under surge conditions?
The SMA5J9.0CAHE3/61 clamps to a maximum of 15.4 V at its rated peak pulse current of 32.5 A (10/1000 µs waveform). This value is measured under standardized test conditions with 5.0 mm × 5.0 mm copper pads per terminal, and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event.
How does SMA5J9.0CAHE3/61 differ from unidirectional variants like SMA5J9.0AHE3/61?
Unlike the unidirectional SMA5J9.0AHE3/61-which has a cathode band and conducts only in reverse bias-the SMA5J9.0CAHE3/61 has no polarity marking and clamps equally in both directions. It lacks forward voltage drop specification (VF) since it is not intended for DC forward conduction, making it unsuitable as a rectifier but optimal for bidirectional surge suppression.
What packaging and reel options are available for SMA5J9.0CAHE3/61?
SMA5J9.0CAHE3/61 is supplied in 7-inch diameter plastic tape and reel with a base quantity of 1800 units (package code /61). The device uses standard EIA-481-compliant carrier tape, supports automated pick-and-place, and complies with J-STD-002 and JESD 22-B102 for solderability and whisker resistance.
