Product details
Overview
SMA5J6.0CA-E3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for robust overvoltage protection on signal and power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 µs), clamping voltage of 10.3 V at 48.5 A IPPM, and operates from –55 °C to +150 °C junction temperature - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J6.0CA-E3/61 datasheet, SMA5J6.0CA-E3/61 pinout, SMA5J6.0CA-E3/61 application, or SMA5J6.0CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, low incremental surge resistance, AEC-Q101 qualification eligibility (via HE3 suffix), UL 94 V-0 molding compound, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response to transients and stable clamping under repetitive surge conditions. Its symmetrical I-V characteristic enables protection of AC-coupled or differential signal paths without polarity concerns.
The device is rated for 500 W peak pulse power per 10/1000 µs waveform, with thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W, supporting reliable operation in compact PCB layouts when mounted per recommended pad dimensions (5.0 mm × 5.0 mm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe signal swing margin in protected circuit. |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold range ensures predictable turn-on across production lot and temperature. |
| VC @ IPPM | 10.3 V at 48.5 A - Clamping voltage during 500 W transient defines maximum stress imposed on downstream ICs like microcontrollers or transceivers. |
| PPPM | 500 W (10/1000 µs) - Peak surge energy handling capacity determines suitability for ISO 7637-2 Pulse 1/2a/5a or IEC 61000-4-5 Level 3/4 compliance designs. |
| TJ max | +150 °C - Enables use in under-hood automotive environments and high-ambient industrial enclosures without derating. |
| Package | SMA (DO-214AC) - Surface-mount outline with 2.54 mm lead pitch; compatible with standard reflow profiles and J-STD-020 MSL level 1 (260 °C peak). |
Pinout & Package
Package: SMA (DO-214AC), 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) | Bidirectional transient conduction path | Both terminals function identically; no cathode band marking - supports AC line or differential pair protection without orientation constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, RS-485 buses, or transformer-coupled interfaces without external polarity management. |
| 500 W peak pulse power | Supports immunity to severe transients including load dump surges and lightning-induced coupling in 12 V/24 V systems. |
| Glass passivated junction | Ensures long-term reliability and stable VBR drift (< ±5 %) over 1000+ surge events and extended thermal cycling. |
| MSL level 1 rating | Permits standard SMT reflow without pre-baking; compatible with high-volume automated assembly using 7" or 13" tape-and-reel delivery (E3/61 = 1800 pcs/reel). |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0CA-M3/61 | Halogen-free, RoHS-compliant variant with identical electrical specs and SMA package; same 500 W PPPM, 10.3 V VC. | No functional difference; selected where halogen-free material compliance is mandated by OEM or regional environmental policy. | Direct substitution if halogen-free requirement applies; no layout or performance change needed. |
| SMA6J6.0CA-E3/61 | Higher 600 W peak pulse power rating, same VWM/VBR/VC, identical SMA package and pinout; slightly higher RθJA (85 °C/W). | Preferred for designs requiring margin above 500 W (e.g., ISO 7637-2 Pulse 5a worst-case), but consumes more board space due to larger die. | Select SMA6J6.0CA-E3/61 only when validated surge test margins exceed 500 W; otherwise SMA5J6.0CA-E3/61 offers optimal cost/performance balance. |
Compared with SMA5J6.0CA-E3/61, the M3 variant adds halogen-free compliance without altering protection performance, while the SMA6J6.0CA-E3/61 increases surge headroom at the cost of marginally reduced thermal efficiency - both require no PCB redesign but serve distinct compliance or margin requirements.

FAQ
What is the polarity configuration of SMA5J6.0CA-E3/61?
The SMA5J6.0CA-E3/61 is a bidirectional TVS diode with symmetrical anode/cathode terminals and no polarity marking on the SMA package. This allows it to protect AC-coupled or differential signal paths - such as RS-485 or CAN bus lines - without orientation sensitivity. Unlike unidirectional variants (e.g., SMA5J6.0A), the SMA5J6.0CA-E3/61 clamps voltage surges equally in both directions, making it ideal for applications where signal polarity is undefined or alternating.
Does SMA5J6.0CA-E3/61 meet AEC-Q101 qualification?
The base part number SMA5J6.0CA-E3/61 is RoHS-compliant and commercial-grade; AEC-Q101 qualification requires the HE3 or HM3 suffix (e.g., SMA5J6.0CAHE3_A). While SMA5J6.0CA-E3/61 shares identical electrical and thermal specifications with its qualified counterparts, only the HE3/HM3 versions undergo the full stress-test sequence per AEC-Q101. For automotive under-hood applications, specify SMA5J6.0CAHE3_A to ensure certified reliability.
What is the maximum clamping voltage of SMA5J6.0CA-E3/61 under surge conditions?
The SMA5J6.0CA-E3/61 has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current (IPPM) of 48.5 A, measured using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during a 500 W transient event and must be compared against the absolute maximum ratings of downstream components - such as microcontroller I/O pins or transceiver inputs - to ensure safe operation.
Can SMA5J6.0CA-E3/61 be used in place of SMA5J6.0A?
No - SMA5J6.0CA-E3/61 is bidirectional, whereas SMA5J6.0A is unidirectional and features a cathode band marking. Substituting them requires verifying circuit topology: SMA5J6.0CA-E3/61 is appropriate for AC, differential, or polarity-agnostic lines, while SMA5J6.0A suits DC-biased rails where reverse conduction must be blocked. Using SMA5J6.0A in a bidirectional application risks failure during negative transients, and SMA5J6.0CA-E3/61 may allow unwanted leakage in DC-only paths due to symmetrical conduction.
What is the thermal resistance and mounting requirement for SMA5J6.0CA-E3/61?
The SMA5J6.0CA-E3/61 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, as specified in the Vishay datasheet. To maintain rated 500 W surge capability and avoid thermal runaway, PCB layout must follow this minimum pad area; reducing pad size increases RθJA, lowering effective power handling and derating the device at elevated ambient temperatures.
