Product details
Overview
SMA5J16A-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on power and signal lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 26.0 V clamping voltage at 19.2 A peak pulse current, and 500 W peak pulse power rating with 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMA5J16A-E3/61 datasheet, SMA5J16A-E3/61 pinout, SMA5J16A-E3/61 application, or SMA5J16A-E3/61 equivalent, key selection criteria include clamping performance under 500 W surge, unidirectional polarity with cathode band marking, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, activating when reverse voltage exceeds its VBR range (17.8–19.7 V) to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1.0 μA at 16 V) and fast response time (<1.0 ps), critical for suppressing ESD and inductive switching spikes.
Rated for -55 °C to +150 °C junction temperature, it delivers 500 W peak pulse power dissipation under standardized 10/1000 μs waveform testing, with thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), enabling reliable operation on standard PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 17.8 V / 19.7 V - verified breakdown threshold range at 1 mA test current |
| VC @ IPPM | 26.0 V at 19.2 A - clamping voltage during full 500 W surge event |
| PPPM | 500 W - peak pulse power handling per 10/1000 μs waveform, derated above 25 °C |
| ID @ VWM | <1.0 μA - ultra-low reverse leakage ensures minimal standby power loss |
| TJ max | +150 °C - maximum junction temperature supports under-hood automotive use |
| Package | SMA (DO-214AC) - surface-mount outline with 5.28 mm length, 4.50 mm width, 2.29 mm height |
Pinout & Package
SMA5J16A-E3/61 uses the SMA (DO-214AC) package: molded plastic case with matte tin-plated leads, polarity indicated by a cathode band on the body. Mounting requires minimum 5.0 mm × 5.0 mm copper pads per terminal per JEDEC standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path (cathode-banded end is opposite) | Connected to ground or low-side reference in unidirectional clamp configuration |
| Cathode | Reverse-biased terminal during normal operation | Connected to protected line; conducts only during overvoltage transients above VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling |

| MSL Level 1 (260 °C peak) | Enables standard reflow soldering without moisture sensitivity concerns |
| AEC-Q101 qualification option | HE3/HM3 variants available for automotive-grade deployment with traceable qualification data |
| RoHS-compliant & halogen-free options | E3 suffix = RoHS-compliant commercial grade; M3 = halogen-free RoHS-compliant |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator surge events up to ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between power rail and chassis ground to clamp transients before they reach MCU power pins. Use Value: Clamps to 26.0 V at 19.2 A, limiting stress on 3.3 V/5 V regulators and preventing latch-up in downstream logic. | Use Scenario: Safeguarding analog front-end inputs of pressure/temperature sensors connected to PLC I/O modules. IC Role / Device Role / Timing Role: Reverse-biased TVS on signal line to absorb ESD (IEC 61000-4-2) and inductive kickback from solenoid drivers. Use Value: Sub-1 μA leakage at 16 V preserves signal integrity in high-impedance sensor bridges; fast response prevents ADC saturation. |
| Consumer Power Adapter Output Protection | Telecom DC Power Feeding Line Protection |
Use Scenario: Secondary-side overvoltage suppression in USB-C PD adapters and AC/DC wall adapters. IC Role / Device Role / Timing Role: Clamp device on regulated 5–20 V output rail to prevent damage during feedback loop failure or transient coupling. Use Value: 500 W surge rating handles worst-case fault energy; 16 V VWM aligns with common USB-PD profiles without false triggering. | Use Scenario: Protection of PoE (Power over Ethernet) powered devices against surges induced on 48 V DC feeding lines. IC Role / Device Role / Timing Role: Unidirectional TVS placed between PSE-supplied DC line and PD input stage to absorb lightning-induced surges. Use Value: 26.0 V clamping ensures safe margin below typical 57 V PoE open-circuit voltage while surviving 500 W pulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J16CA-E3/61 | Bidirectional variant; symmetric VBR (17.8–19.7 V) in both polarities; no polarity marking | Required for AC-coupled or floating signal lines where reverse polarity transients occur | Select SMA5J16CA-E3/61 only when bidirectional clamping is mandated by system topology |
| SMC5J16A-E3/61 | Larger SMC (DO-214AB) package; same electrical specs but higher thermal mass (RθJA = 35 °C/W vs. 80 °C/W) | Better suited for high-repetition surge environments or elevated ambient temperatures (>85 °C) | Choose SMC5J16A-E3/61 when board space allows and thermal derating margins are insufficient with SMA |
Compared with SMA5J16A-E3/61, SMA5J16CA-E3/61 enables symmetrical protection without polarity constraints but sacrifices unidirectional leakage advantage; SMC5J16A-E3/61 improves thermal robustness at the cost of footprint size and assembly compatibility with fine-pitch SMT lines.

FAQ
What is the clamping voltage of SMA5J16A-E3/61 under full-rated surge conditions?
The SMA5J16A-E3/61 clamps to 26.0 V when subjected to its maximum rated peak pulse current of 19.2 A, measured using the standardized 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet and reflects actual device behavior under worst-case surge conditions, ensuring protected circuits remain within safe voltage limits. The SMA5J16A-E3/61 achieves this with low incremental resistance and fast junction response.
Is SMA5J16A-E3/61 suitable for automotive applications?
SMA5J16A-E3/61 is RoHS-compliant and qualified for commercial-grade use; however, the AEC-Q101-qualified variant is SMA5J16AHE3_A/E3. While the base SMA5J16A-E3/61 meets many automotive environmental requirements (e.g., -55 °C to +150 °C TJ), formal qualification requires the HE3 suffix. For production automotive ECUs, specify SMA5J16AHE3_A/E3 - the SMA5J16A-E3/61 itself is widely used in non-safety-critical subsystems like infotainment power rails.
What does the "-E3/61" suffix mean in SMA5J16A-E3/61?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads; "/61" denotes packaging in 7-inch diameter plastic tape and reel, with 1800 units per reel. This format supports high-speed pick-and-place assembly. The SMA5J16A-E3/61 is not halogen-free (that requires "M3") nor AEC-Q101 qualified (which requires "HE3" or "HM3"), distinguishing it from automotive-grade versions of the same device.
How does SMA5J16A-E3/61 compare to SMAJ16A in terms of surge capability?
SMA5J16A-E3/61 delivers 500 W peak pulse power, whereas SMAJ16A is rated for 400 W under identical 10/1000 μs conditions. This 25 % higher energy handling stems from optimized chip geometry and thermal design in the SMA5J family. Both share the same SMA package and VWM/VBR specs, but SMA5J16A-E3/61 provides greater margin for severe transients such as ISO 7637-2 Pulse 5a in automotive systems.
Can SMA5J16A-E3/61 be used in bidirectional signal line protection?
No - SMA5J16A-E3/61 is strictly unidirectional and must be installed with correct polarity (cathode band toward the protected line). For bidirectional protection, use SMA5J16CA-E3/61, which exhibits matched breakdown characteristics in both directions and lacks polarity marking. Using SMA5J16A-E3/61 on AC or floating signals risks forward conduction during negative transients, potentially damaging the device or failing to protect.
