Product details
Overview
SMA5J26CA-E3/61 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 26 V stand-off voltage (VWM), 42.1 V maximum clamping voltage (VC) at 11.9 A peak pulse current (IPPM), and 500 W peak pulse power (10/1000 μs waveform), used to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients in automotive and industrial control systems.
For engineers reviewing the SMA5J26CA-E3/61 datasheet, SMA5J26CA-E3/61 pinout, SMA5J26CA-E3/61 application, or SMA5J26CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, low incremental surge resistance, AEC-Q101 qualification eligibility (via HE3 suffix), RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 28.9 V and 31.9 V at 1 mA test current. Its clamping behavior is characterized under standardized 10/1000 μs surge waveforms, delivering consistent VC ≤ 42.1 V up to IPPM = 11.9 A while maintaining thermal resistance RθJA = 80 °C/W.
The device uses a glass-passivated silicon junction and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak. Polarity is unmarked-consistent with bidirectional construction-and it supports operating junction temperatures from –55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 26 V - Maximum continuous reverse working voltage before clamping initiates |
| VBR (min/max) | 28.9 V / 31.9 V - Breakdown threshold range at 1 mA, defining turn-on consistency |
| VC @ IPPM | 42.1 V - Clamped voltage during 500 W surge, limiting stress on protected downstream components |
| IPPM | 11.9 A - Peak surge current handled at 10/1000 μs waveform without failure |
| PPPM | 500 W - Transient energy absorption capacity, enabling robust protection in harsh EMI environments |
| TJ max. | +150 °C - Maximum junction temperature, supporting operation in under-hood automotive and industrial enclosures |
| RθJA | 80 °C/W - Thermal resistance from junction to ambient, guiding PCB copper pad sizing for thermal reliability |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002. No polarity marking - consistent with bidirectional functionality.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional terminal pair | Either end accepts reverse or forward surge; no cathode band marking required |
Key Features
| Feature | Design Value |

| AEC-Q101 qualification path | HE3/HM3 variants available for automotive applications requiring validated stress testing |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V CAN bus power rails and LIN transceivers from load dump and jump-start surges. IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed across VCC and GND upstream of DC-DC converters and interface ICs. Use Value: Limits transient voltage to ≤42.1 V during 500 W surges, preventing latch-up or gate oxide damage in downstream 3.3 V/5 V logic. |

IC Role / Device Role / Timing Role: Primary overvoltage clamp on sensor supply and signal return paths in DIN-rail mounted controllers. Use Value: Maintains signal integrity by clamping sub-μs transients below system-level immunity thresholds (IEC 61000-4-4/5). |
| Consumer Appliance Motor Control | Telecom Power Supply Input |

IC Role / Device Role / Timing Role: First-stage clamping device before bulk capacitance and active regulation circuitry. Use Value: Delivers 500 W peak power handling with <1 ns response time, reducing reliance on slower MOV-based secondary protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J26A-E3/61 | Unidirectional variant; same VWM, VBR, VC, and PPPM, but marked with cathode band and not suitable for AC or floating lines | Requires polarity-aware layout; limited to DC supply rail or unidirectional signal protection | Select only when protecting grounded DC paths where reverse conduction must be blocked |
| SMCJ26CA-E3/73 | Same VWM/VC ratings but in larger SMC (DO-214AB) package; higher IPPM = 22.5 A and PPPM = 1500 W | Occupies ~2.5× PCB area; suited for higher-energy threats (e.g., ISO 16750-2 Load Dump) | Choose when surge threat level exceeds 500 W or board space allows larger footprint for margin |
Compared with SMA5J26CA-E3/61, the unidirectional SMA5J26A-E3/61 offers identical electrical protection in DC-only contexts but lacks AC symmetry, while the SMCJ26CA-E3/73 provides 3× power handling at the cost of footprint - making SMA5J26CA-E3/61 optimal for space-constrained 500 W bidirectional protection.

FAQ
What is the clamping voltage of the SMA5J26CA-E3/61 under a 10/1000 μs surge?
The SMA5J26CA-E3/61 clamps to a maximum of 42.1 V when subjected to its rated peak pulse current of 11.9 A using the standardized 10/1000 μs waveform. This value is measured at the device terminals under defined test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads) and represents the upper limit of voltage seen by protected circuitry during surge events.
Is the SMA5J26CA-E3/61 suitable for automotive applications?
Yes - the SMA5J26CA-E3/61 is RoHS-compliant and manufactured to Vishay's commercial-grade specifications. While the base E3/61 variant is not AEC-Q101 qualified, the pin-compatible SMA5J26CAHE3_A/H variant (same electrical specs, HE3 suffix) is fully AEC-Q101 qualified and intended for automotive use. Designers requiring automotive qualification should specify the HE3 version.
Does the SMA5J26CA-E3/61 have polarity markings?
No - the SMA5J26CA-E3/61 is a bidirectional TVS diode and carries no cathode band or other polarity marking. Its symmetrical construction allows installation in either orientation across protected lines, simplifying layout and eliminating orientation errors during automated assembly.
What is the thermal resistance of the SMA5J26CA-E3/61?
The SMA5J26CA-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes still air conditions and guides thermal design for sustained surge duty cycles or elevated ambient temperatures.
How does the SMA5J26CA-E3/61 differ from the SMA5J26A-E3/61?
The SMA5J26CA-E3/61 is bidirectional, while the SMA5J26A-E3/61 is unidirectional. Both share identical VWM (26 V), VBR (28.9–31.9 V), VC (42.1 V), and PPPM (500 W), but only the "A" version includes a cathode band and blocks reverse current. The "CA" version clamps equally in both directions and has no marking - making it suitable for AC, floating, or differential signal protection.
