Product details
Overview
SMA5J16-E3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on DC power rails and signal lines. It features 16 V stand-off voltage (VWM), 26.0 V clamping voltage (VC) at 19.2 A peak pulse current (IPPM), 500 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMA5J16-E3/5A datasheet, SMA5J16-E3/5A pinout, SMA5J16-E3/5A application, or SMA5J16-E3/5A equivalent, key selection criteria include clamping performance under 10/1000 µs transients, unidirectional polarity 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: when reverse voltage exceeds 16 V (VWM), it avalanches at 17.8–19.7 V (VBR min/max), limiting transient energy to ≤26.0 V at 19.2 A. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at VWM).
Thermal design relies on RθJA = 80 °C/W (typ.) and RθJL = 25 °C/W (typ.), with maximum junction temperature of +150 °C. It meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 1A whisker testing due to its E3 suffix.
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 1.0 mA test current; defines turn-on threshold |
| VC @ IPPM | 26.0 V at 19.2 A - Clamped voltage during 10/1000 µs surge; determines protected circuit's max stress level |
| PPPM | 500 W - Peak pulse power handling capability; sets surge energy limit (e.g., 500 W × 1 ms = 0.5 J) |
| IFSM | 40 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports inrush or fault-current events |
| TJ max | +150 °C - Maximum junction temperature; constrains thermal design margin in enclosed environments |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, low-profile case with cathode band marking. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal (cathode-banded end is opposite) | Connected to lower-potential side (e.g., GND) in unidirectional configuration; enables clamping only during reverse overvoltage |
| Cathode | Reverse-biased terminal (marked with band) | Connected to protected line (e.g., 12 V rail); avalanche conduction occurs when voltage exceeds VWM relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| Low incremental surge resistance | Enables tight clamping (26.0 V at 19.2 A), minimizing voltage overshoot during fast transients |
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress |
| AEC-Q101 qualification | Validated for automotive under-hood and body-control module applications per stress test requirements |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without moisture-induced failure risk |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator switching transients. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between power rail and ground, clamping surges above 16 V. Use Value: Limits rail voltage to ≤26.0 V during 19.2 A transients, preventing damage to downstream regulators and microcontrollers. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) in PLC I/O modules exposed to field-wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: Point-of-entry TVS on signal line, referenced to local ground, suppressing ±15 kV ESD (IEC 61000-4-2) and 40 A lightning surges. Use Value: Low leakage (<1.0 µA) avoids signal offset errors; fast response preserves signal integrity in sub-100 ns transients. |
| Consumer USB Power Port Protection | Telecom DC Feeder Line Protection |
Use Scenario: Securing 5 V/9 V USB PD input stages in portable chargers and docking stations against hot-plug and cable discharge events. IC Role / Device Role / Timing Role: Unidirectional TVS between VBUS and GND, sized for 500 W pulse handling and 16 V nominal operation.

IC Role / Device Role / Timing Role: Series-connected unidirectional TVS on feed line, with cathode toward load, blocking reverse faults while clamping positive surges. Use Value: Withstands 40 A IFSM, enabling robust protection in central office and remote cabinet deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J16AHE3/5A | AEC-Q101 qualified variant with identical electrical specs; HE3 suffix denotes enhanced whisker resistance (JESD 201 Class 2) | Required for automotive safety-critical modules where Class 2 whisker immunity is mandated | Select SMA5J16AHE3/5A when AEC-Q101 compliance and higher whisker resistance are mandatory; otherwise SMA5J16-E3/5A suffices for commercial/industrial use |
| SMC5J16A-E3/57T | Same VWM/VC but in larger DO-214AB (SMC) package; higher IPPM (21.6 A → 32.5 A) and PPPM (1500 W) | Suitable for higher-energy surge environments (e.g., industrial motor drives) where PCB space allows larger footprint | Choose SMC5J16A-E3/57T only if 1500 W surge rating is required and DO-214AB layout is acceptable; SMA5J16-E3/5A remains optimal for space-constrained designs needing 500 W |
Compared with SMA5J16AHE3/5A and SMC5J16A-E3/57T, the SMA5J16-E3/5A offers the best balance of AEC-Q101 readiness, compact DO-214AC footprint, and 500 W surge capability-making it ideal for cost-sensitive automotive body electronics and industrial control panels where board area is constrained.

FAQ
What is the clamping voltage of the SMA5J16-E3/5A under a 10/1000 µs surge?
The SMA5J16-E3/5A 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 circuits during surge events. The SMA5J16-E3/5A maintains this clamping performance consistently across its operational temperature range.
Is the SMA5J16-E3/5A suitable for automotive applications?
Yes, the SMA5J16-E3/5A is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and body electronics. Its construction includes glass-passivated junctions, MSL Level 1 moisture sensitivity, and JESD 201 Class 1A whisker resistance-all validated per automotive stress test requirements. The SMA5J16-E3/5A is commonly deployed in engine control units, lighting modules, and infotainment power supplies where transient immunity to load dump and ISO 7637-2 pulses is critical.
How does the E3 suffix affect the SMA5J16-E3/5A?
The E3 suffix on SMA5J16-E3/5A indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads that meet J-STD-002 and JESD 22-B102 solderability standards. It also certifies compliance with JESD 201 Class 1A whisker testing, ensuring reliability in high-vibration environments. The "5A" denotes packaging in 13-inch tape-and-reel format with 7500 units per reel-distinct from the "61" code used for 7-inch reels.
What is the maximum operating temperature for the SMA5J16-E3/5A?
The SMA5J16-E3/5A has a maximum junction temperature (TJ) of +150 °C and an operating junction/storage temperature range of -55 °C to +150 °C. This rating allows reliable operation in under-hood automotive environments and industrial enclosures. Thermal design must account for RθJA = 80 °C/W (typ.) and RθJL = 25 °C/W (typ.), especially under sustained power dissipation or elevated ambient conditions.
Does the SMA5J16-E3/5A have polarity marking, and how is it oriented in circuit?
Yes, the SMA5J16-E3/5A is unidirectional and features a visible cathode band on the package body. In circuit, the banded end (cathode) connects to the line being protected (e.g., 12 V rail), while the anode connects to ground. This orientation ensures the device remains non-conductive during normal operation (reverse-biased below VWM = 16 V) and avalanches only during overvoltage events, diverting surge current safely to ground. The SMA5J16-E3/5A must not be installed in reverse polarity.
