Product details
Overview
SMA5J11CHE3/61 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on power and signal lines. It features 11 V stand-off voltage (VWM), 12.2–13.5 V breakdown voltage (VBR), 18.2 V maximum clamping voltage (VC) at 27.5 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 μs waveform. Used in automotive sensor protection and industrial I/O interfaces.
For engineers reviewing the SMA5J11CHE3/61 datasheet, SMA5J11CHE3/61 pinout, SMA5J11CHE3/61 application, or SMA5J11CHE3/61 equivalent, key selection criteria include bi-directional polarity, AEC-Q101 qualification, 150 °C max junction temperature, RoHS-compliant HE3 suffix, and DO-214AC thermal resistance (RθJA = 80 °C/W).
Technical Context
This bi-directional TVS operates symmetrically in both reverse and forward directions, with clamping action triggered when transient voltage exceeds VBR (12.2–13.5 V). Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time under ESD and lightning surge conditions.
Designed for surface-mount placement on 0.2" × 0.2" copper pads per terminal, it delivers 500 W surge handling with low incremental surge resistance and meets MSL Level 1 (260 °C reflow peak). The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous reverse stand-off voltage before clamping begins |
| VBR min/max | 12.2 V / 13.5 V - Breakdown occurs within this range at 1 mA test current |
| VC @ IPPM | 18.2 V at 27.5 A - Clamped voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 500 W - Peak transient power dissipation capability under standardized waveform |
| TJ max | +150 °C - Maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 80 °C/W - Thermal resistance from junction to ambient on standard PCB pad layout |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed across differential or single-ended signal lines upstream of IC input pins. Use Value: Limits transient voltage to ≤18.2 V, preventing damage to 3.3 V/5 V interface logic while maintaining signal integrity during 10/1000 μs surges. | Use Scenario: Safeguarding digital input modules in programmable logic controllers against field-wiring induced transients and relay coil flyback. IC Role / Device Role / Timing Role: Parallel-connected TVS on 24 V DC input channels to shunt surge energy before reaching optocoupler or microcontroller GPIO. Use Value: Withstands repeated 500 W surges without degradation, ensuring >100,000-cycle reliability in factory automation environments. |
| Telecom Line Interface | Consumer Power Adapter ESD Protection |
Use Scenario: Shielding Ethernet PHY magnetics and PoE injectors from lightning-induced common-mode surges on twisted-pair cabling. IC Role / Device Role / Timing Role: Bi-directional TVS deployed across line pairs (e.g., tip/ring) to clamp mode-common transients before transformer primary windings. Use Value: Symmetrical clamping prevents DC bias shift on differential signals and maintains IEEE 802.3af compliance under surge stress. | Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters to protect USB-C PD controllers and battery management ICs. IC Role / Device Role / Timing Role: Clamp placed between +VOUT and GND to absorb output capacitor discharge spikes and ESD events during hot-plug.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J11CA-E3/61 | Same VWM/VBR/VC specs but E3 suffix (commercial grade, not AEC-Q101 qualified) | Lacks automotive qualification; suitable for industrial/commercial designs without automotive reliability requirements | Select SMA5J11CA-E3/61 only if AEC-Q101 is not mandated and cost sensitivity outweighs qualification needs |
| SMCJ11CAHE3/61 | Same bi-directional function but DO-214AB (SMC) package; higher PPPM (1500 W), larger footprint, RθJA = 25 °C/W | Better thermal performance and surge margin; requires PCB redesign due to larger 7.11 mm × 6.22 mm outline vs. SMA's 4.93 mm × 3.99 mm | Choose SMCJ11CAHE3/61 when 1500 W surge rating or lower thermal resistance is required and board space permits |
Compared with SMA5J11CA-E3/61, the SMA5J11CHE3/61 adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance-critical for automotive under-hood use-while sharing identical electrical specs. Versus SMCJ11CAHE3/61, it trades 3× lower surge power and higher thermal resistance for 40 % smaller PCB area and SMT compatibility with tighter pitch layouts.

FAQ
What is the polarity configuration of SMA5J11CHE3/61?
The SMA5J11CHE3/61 is a bi-directional transient voltage suppressor, meaning it functions identically in both forward and reverse bias. Unlike uni-directional variants, it has no cathode band marking and provides symmetrical clamping above ±12.2 V breakdown. This makes SMA5J11CHE3/61 ideal for protecting AC-coupled or differential signal paths where polarity reversal may occur during transients.
Does SMA5J11CHE3/61 meet automotive qualification standards?
Yes, SMA5J11CHE3/61 is AEC-Q101 qualified, as confirmed by its HE3 suffix and Vishay documentation. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-ensuring reliability in automotive under-hood and chassis-mounted applications. The SMA5J11CHE3/61 is explicitly rated for TJ max = +150 °C, supporting engine control and ADAS subsystem deployment.
What is the maximum clamping voltage of SMA5J11CHE3/61 during a surge event?
The SMA5J11CHE3/61 clamps to a maximum of 18.2 V when subjected to its rated 27.5 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This VC value is measured at the device terminals and represents the upper voltage limit imposed on protected circuitry during surge conditions-critical for ensuring downstream ICs with 20 V absolute maximum ratings remain within safe operating limits.
How does the HE3 suffix differ from E3 in SMA5J11CHE3/61?
The HE3 suffix in SMA5J11CHE3/61 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates commercial-grade RoHS compliance only. Both share identical electrical specifications and DO-214AC packaging, but HE3 undergoes additional automotive-specific screening-including extended temperature cycling and mechanical shock testing-making SMA5J11CHE3/61 suitable for automotive safety-critical systems where E3 variants are not permitted.
What PCB layout guidance applies to SMA5J11CHE3/61 for optimal thermal performance?
Vishay specifies that SMA5J11CHE3/61 must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve its rated 500 W peak pulse power and RθJA = 80 °C/W. Reducing pad size increases thermal resistance and de-rates surge capability; adding internal copper planes or thermal vias beneath pads further improves heat dissipation. The SMA5J11CHE3/61 datasheet Fig. 2 provides derating curves for elevated ambient temperatures.
