Product details
Overview
SMA5J13-E3/61 from Vishay General Semiconductor is a unidirectional 500 W Transient Voltage Suppressor (TVS) diode in DO-214AC (SMA) package, with 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), and 23.3 A peak pulse current (IPPM) under 10/1000 µs waveform - used to protect MOSFETs and signal lines in automotive power electronics against inductive switching transients.
For engineers reviewing the SMA5J13-E3/61 datasheet, SMA5J13-E3/61 pinout, SMA5J13-E3/61 application, or SMA5J13-E3/61 equivalent, this page delivers verified electrical parameters, JEDEC-compliant thermal resistance (RθJA = 80 °C/W), AEC-Q101 qualification status, RoHS-compliant E3 termination, and real-world clamping behavior (VC = 21.5 V at IPPM) for robust overvoltage design validation.
Technical Context
This unidirectional TVS diode operates as a clamping device across power rails or signal paths, activating when reverse voltage exceeds VBR (14.4–15.9 V) to limit transient energy. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM = 13 V) and fast response time (<1 ns).
Designed for surface-mount automation, it uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets MSL Level 1 (260 °C peak reflow). The DO-214AC package provides 80 °C/W junction-to-ambient thermal resistance and supports 40 A non-repetitive forward surge (IFSM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 14.4 V / 15.9 V - Breakdown threshold range at 1 mA test current; defines turn-on consistency |
| VC @ IPPM | 21.5 V - Clamped voltage during 23.3 A 10/1000 µs surge; determines protected circuit's maximum stress |
| PPPM | 500 W - Peak pulse power handling capacity; sets survivability against standardized lightning/surge events |
| IPPM | 23.3 A - Peak surge current capability at VC; directly correlates with PCB trace sizing and layout margin |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance; informs derating above 25 °C ambient |
| TJ max. | +150 °C - Maximum junction temperature; constrains sustained power dissipation in enclosed environments |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode band marking on one end; 0.208" × 0.157" footprint, 0.078" lead width, and 0.100" lead spacing. Designed for automated placement and reflow soldering per J-STD-020 MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path (uni-directional only) | Connected to lower-potential side of protected line; conducts during positive surges if used in reverse-biased configuration |
| Cathode (banded end) | Clamping node (reverse-biased operation) | Connected to higher-potential rail; avalanche conduction initiates here when VWM exceeded |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and low leakage (<1.0 µA) across temperature and lifetime |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients, improving protection margin for downstream ICs |
| RoHS-compliant E3 termination | Matte tin plating meets JESD 201 Class 1A whisker resistance and J-STD-002 solderability standards |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Suppresses load-dump and inductive kickback transients on 12 V battery-fed ECUs and body control modules. IC Role / Device Role: Unidirectional TVS placed between power rail and ground to clamp surges above 13 V. Use Value: Limits peak rail voltage to 21.5 V during 23.3 A transients, preventing damage to 24 V-rated microcontrollers and CAN transceivers. | Use Scenario: Shields analog output lines (e.g., 4–20 mA current loops) from ESD and field-induced spikes in factory automation sensors. IC Role / Device Role: TVS connected between signal line and ground, leveraging fast <1 ns response to divert sub-microsecond threats. Use Value: Maintains signal integrity by clamping transients before they reach precision ADC inputs, with <1.0 µA leakage preserving loop accuracy. |
| Consumer Power Adapter Input Stage | MOSFET Gate Driver Surge Suppression |
Use Scenario: Protects primary-side controller ICs in AC/DC adapters against line surges and capacitor discharge spikes. IC Role / Device Role: Mounted across bulk capacitor terminals to absorb energy from 500 W 10/1000 µs transients. Use Value: Withstands repeated 23.3 A pulses without degradation, enabling compliance with IEC 61000-4-5 Level 3 immunity testing. | Use Scenario: Prevents gate oxide rupture in high-side N-channel MOSFETs during fast-switching power converter turn-off events. IC Role / Device Role: Placed between gate and source to clamp Miller-induced voltage spikes exceeding 13 V. Use Value: Fast avalanche response limits gate-source voltage to 21.5 V, avoiding destructive overvoltage while adding no capacitance penalty to switching node. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J13AHE3/61 | AEC-Q101 qualified variant with identical VWM, VBR, and PPPM; same DO-214AC package and E3 termination | Required for automotive production where full AEC-Q101 documentation and lot traceability are mandated | Select SMA5J13AHE3/61 when automotive PPAP submission or long-term vehicle program support is required |
| SMC5J13A-E3/57T | Higher-power 1500 W SMC package variant; same 13 V VWM, but larger footprint and 35.5 A IPPM | Suitable for systems requiring higher single-pulse energy absorption or extended thermal margin | Choose SMC5J13A-E3/57T only when PCB space allows larger package and surge requirements exceed 500 W |
Compared with SMA5J13-E3/61, the HE3 variant adds formal AEC-Q101 certification without altering electrical performance, while the SMC5J13A-E3/57T trades compactness for 3× pulse power headroom - making SMA5J13-E3/61 optimal for cost-sensitive, space-constrained automotive and industrial designs needing validated 500 W protection.

FAQ
What is the clamping voltage of the SMA5J13-E3/61 under standard surge conditions?
The SMA5J13-E3/61 clamps to 21.5 V when subjected to its rated 10/1000 µs surge waveform at 23.3 A (IPPM). This value is measured at TA = 25 °C with recommended pad layout and represents the maximum voltage seen by downstream components during transient events - critical for ensuring compatibility with 24 V logic and interface ICs.
Is the SMA5J13-E3/61 AEC-Q101 qualified?
No - the SMA5J13-E3/61 carries the commercial-grade E3 suffix and is RoHS compliant but not AEC-Q101 qualified. For automotive production requiring AEC-Q101 certification, the functionally identical SMA5J13AHE3/61 variant must be selected, which shares the same electrical specs and DO-214AC package but includes full qualification documentation.
What does the "-E3/61" suffix indicate in SMA5J13-E3/61?
The "E3" denotes RoHS-compliant matte tin plating meeting JESD 201 Class 1A whisker resistance and J-STD-002 solderability; "61" specifies the preferred packaging code for 7-inch plastic tape-and-reel delivery with 1800 units per reel - standard for SMT assembly lines requiring automated pick-and-place compatibility.
How does the SMA5J13-E3/61 compare to bi-directional TVS diodes like SMA5J13CA?
The SMA5J13-E3/61 is unidirectional and blocks forward current beyond its VF (~3.5 V at 25 A), whereas SMA5J13CA is bi-directional with symmetrical clamping in both polarities. Use SMA5J13-E3/61 for DC power rail protection where polarity is fixed; choose SMA5J13CA only when AC-coupled or bidirectional signal lines require suppression in both directions.
What is the thermal resistance and maximum junction temperature of the SMA5J13-E3/61?
The SMA5J13-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" copper pads, and a maximum junction temperature (TJ) of +150 °C. These values define safe continuous power dissipation limits and require derating above 25 °C ambient per Figure 2 in the Vishay datasheet 88875.
