Product details
Overview
SMA5J16AHE3/5A 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 (VC) at 19.2 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial power supply rails.
For engineers reviewing the SMA5J16AHE3/5A datasheet, SMA5J16AHE3/5A pinout, SMA5J16AHE3/5A application, or SMA5J16AHE3/5A equivalent, key selection criteria include clamping performance under 19.2 A surge, AEC-Q101 qualification status, thermal resistance (RθJA = 80 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its breakdown threshold is specified at 1 mA test current, with maximum reverse leakage of 1.0 µA at 16 V stand-off voltage.
The device is rated for junction temperatures from –55 °C to +150 °C, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and is qualified to AEC-Q101 for automotive use - confirmed by HE3 suffix and "AEC-Q101 qualified" designation in Vishay's ordering code structure.
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 - breakdown occurs within this range at 1 mA, defining turn-on threshold tolerance |
| VC @ IPPM | 26.0 V at 19.2 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 500 W - peak transient power it can absorb without failure under standard waveform |
| RθJA | 80 °C/W - thermal resistance from junction to ambient, critical for PCB pad layout design |
| TJ max | +150 °C - maximum allowable junction temperature, enabling operation in under-hood automotive environments |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line (e.g., 16 V rail); conducts during overvoltage to shunt surge to ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over lifetime and improved humidity resistance vs. epoxy-passivated alternatives |
| AEC-Q101 qualification | Validates reliability for automotive applications including engine control units and ADAS sensor interfaces |
| MSL Level 1 rating | Enables single-reflow assembly without moisture sensitivity concerns (260 °C peak) |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving clamping precision |
Applications
| Automotive Sensor Protection | Industrial Power Rail Clamping |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp surges above 16 V while remaining inert during normal operation. Use Value: Limits clamped voltage to 26.0 V during 19.2 A surge, preventing damage to 3.3 V/5 V interface ICs downstream. | Use Scenario: Safeguarding 12–24 V DC input stages of PLC I/O modules and motor drive controllers against lightning-induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Primary front-end surge suppressor on main power entry, coordinated with upstream fuses and downstream LC filters. Use Value: Absorbs 500 W transient energy without degradation, maintaining system uptime in harsh factory environments. |
| Consumer Power Adapter Input | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for laptops and monitors, guarding against internal regulator faults or capacitor failures. IC Role / Device Role / Timing Role: Standoff-rated protector on +16 V output rail, activated only during abnormal overvoltage events. Use Value: Withstands repeated 10/1000 µs surges up to 19.2 A while exhibiting <1.0 µA leakage at nominal voltage - preserving efficiency. | Use Scenario: Protecting Ethernet PHY power pins and auxiliary bias rails in PoE-powered switches and base stations from ESD and induced surges. IC Role / Device Role / Timing Role: Fast-response clamping element on 12 V or 24 V bias lines feeding RF front-end components. Use Value: Sub-nanosecond response ensures clamping initiates before sensitive RF ICs experience overstress, validated per IEC 61000-4-5. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J16A-E3/5A | No AEC-Q101 qualification; commercial-grade only; same electrical specs and package | Not approved for automotive production; suitable for consumer/industrial prototypes | Select when AEC-Q101 is not required and cost sensitivity outweighs automotive compliance |
| SMA5J16CAHE3/5A | Bidirectional variant; symmetric clamping in both polarities; VBR min/max = 17.8–19.7 V same, but ID limit doubled for VWM ≤10 V (not applicable here) | Required for AC-coupled or floating signal lines where polarity reversal may occur | Choose only if bidirectional protection is needed - SMA5J16AHE3/5A is strictly unidirectional |
Compared with SMA5J16A-E3/5A, the HE3 suffix adds AEC-Q101 validation and extended temperature reliability; compared with SMA5J16CAHE3/5A, the unidirectional configuration provides tighter leakage control (1.0 µA vs. 2.0 µA for bidirectional at same VWM) and avoids unnecessary symmetry overhead in DC rail protection.

FAQ
What is the clamping voltage of the SMA5J16AHE3/5A under a 10/1000 µs surge?
The SMA5J16AHE3/5A clamps to a maximum of 26.0 V when subjected to its rated peak pulse current of 19.2 A using the standardized 10/1000 µs waveform. This value is measured at the device terminals under specified test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads), and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the SMA5J16AHE3/5A qualified for automotive applications?
Yes, the SMA5J16AHE3/5A is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code and explicit mention in Vishay's documentation. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge endurance - making SMA5J16AHE3/5A suitable for under-hood and cabin ECU designs requiring automotive-grade reliability.
What does the "/5A" in SMA5J16AHE3/5A indicate?
The "/5A" denotes the packaging configuration: 7500 units per 13-inch diameter plastic tape-and-reel. It is part of Vishay's ordering convention where "5A" specifies reel size and quantity, distinct from the "/61" option (1800 units on 7-inch reel). The electrical and reliability characteristics of SMA5J16AHE3/5A remain identical across packaging variants.
How does the SMA5J16AHE3/5A differ from the SMA5J16A-E3/5A?
The SMA5J16AHE3/5A includes AEC-Q101 qualification and is rated for automotive use, whereas the SMA5J16A-E3/5A is commercial-grade only. Both share identical electrical parameters (VWM = 16 V, VC = 26.0 V, PPPM = 500 W) and SMA package, but only SMA5J16AHE3/5A carries the extended reliability validation required for production automotive programs.
What is the maximum reverse leakage current for SMA5J16AHE3/5A at its stand-off voltage?
The maximum reverse leakage current (ID) for SMA5J16AHE3/5A is 1.0 µA when biased at its 16 V stand-off voltage (VWM) and tested at TA = 25 °C. This low leakage preserves system efficiency in always-on circuits and ensures minimal power loss in battery-backed or low-quiescent-current applications using SMA5J16AHE3/5A.
