Product details
Overview
SMA5J6.5-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR at 10 mA), 500 W peak pulse power (10/1000 µs), 44.6 A peak pulse current (IPPM), and clamps to ≤11.2 V at rated surge. It is widely used in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMA5J6.5-E3/61 datasheet, SMA5J6.5-E3/61 pinout, SMA5J6.5-E3/61 application, or SMA5J6.5-E3/61 equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, AEC-Q101 qualification (via HE3 variant), RoHS-compliant matte tin plating, and MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode operates as a voltage-clamping device in series with the protected line, conducting only when reverse voltage exceeds VBR. Its glass-passivated junction ensures stable leakage (<500 µA at VWM) and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients.
Designed for surface-mount placement on 0.2" × 0.2" copper pads per terminal, it delivers 500 W surge capability under standardized 10/1000 µs waveform conditions. Thermal resistance is 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - Ensures predictable turn-on threshold across production lot |
| IPPM | 44.6 A (10/1000 µs) - Sustains high-energy surges without failure under standard test condition |
| VC | ≤11.2 V at IPPM - Limits downstream voltage stress to safe levels for 5 V logic and analog ICs |
| PPPM | 500 W - Peak pulse power handling capacity defines robustness against IEC 61000-4-5 surge events |
| TJ max | +150 °C - Enables use in under-hood automotive and high-temperature industrial environments |
| RθJA | 80 °C/W - Guides PCB thermal pad design for sustained power dissipation |
Pinout & Package
DO-214AC (SMA) surface-mount package with molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102; cathode indicated by band at one end.

| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free reflow processes without preconditioning or dry-pack requirements |
| 500 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 Level 4 (4 kV line-to-ground) surge immunity requirements |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 5 V supply lines in engine control units (ECUs) and body control modules (BCMs) from load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between VIN and GND, absorbing energy before it reaches downstream regulators and microcontrollers. Use Value: Clamps to ≤11.2 V during 44.6 A surge, preventing latch-up or permanent damage to 5 V-rated components while maintaining system uptime. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) in industrial pressure and temperature transmitters exposed to field wiring transients. IC Role / Device Role / Timing Role: Standoff protector on signal path, remaining non-conductive below 6.5 V and activating within nanoseconds upon overvoltage. Use Value: Low leakage (<500 µA) avoids signal offset errors; fast response preserves signal integrity during ESD events per IEC 61000-4-2. |
| Consumer USB Port ESD Protection | Telecom DC Power Input Protection |
Use Scenario: Secondary-level ESD protection on VBUS line of USB 2.0 ports in set-top boxes and smart displays. IC Role / Device Role / Timing Role: High-power TVS placed after primary polymer PTC, providing low-clamping backup for ±15 kV contact discharge events. Use Value: 11.2 V clamping voltage ensures USB PHY ICs (rated to 6.5 V abs max) remain within safe operating area during multi-kV transients. | Use Scenario: Front-end surge suppression on 12 V DC input of telecom remote radio units (RRUs) mounted on cell towers. IC Role / Device Role / Timing Role: Primary transient shunt on main power entry, diverting lightning-induced surges away from DC/DC converters and FPGAs. Use Value: 500 W rating supports repeated exposure to IEC 61000-4-5 2 kV/500 A surges without degradation, extending field service life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.5A-E3/61 | Same electrical specs and package; differs only in marking code (5AK vs. unspecified); identical VBR, VC, and PPPM | No functional difference; both intended for uni-directional 6.5 V rail protection | Select SMA5J6.5A-E3/61 if traceability to original Vishay marking code is required for audit or legacy BOM alignment |
| SMA6J6.5A-E3/61 | Higher 600 W PPPM, same VWM/VBR, but larger DO-214AB (SMB) package (4.58 mm × 3.94 mm vs. 4.50 mm × 2.79 mm) | Requires PCB footprint change; suitable where higher surge margin is prioritized over board space | Choose SMA6J6.5A-E3/61 only when design requires >500 W surge headroom and layout allows larger SMB footprint |
Compared with SMA5J6.5A-E3/61, the SMA5J6.5-E3/61 offers identical protection performance in the same DO-214AC package but may differ in internal traceability coding; versus SMA6J6.5A-E3/61, it trades 100 W peak power for 30% smaller PCB area and lower thermal mass-critical for dense automotive modules.

FAQ
What is the polarity configuration of SMA5J6.5-E3/61?
The SMA5J6.5-E3/61 is a unidirectional transient voltage suppressor diode. Its cathode is marked by a band on the DO-214AC (SMA) package body, and it conducts only when the cathode is biased positively relative to the anode-making it suitable for DC rail protection where polarity is fixed. This differs from bi-directional variants (e.g., SMA5J6.5CA) that protect AC or bidirectional signal lines.
Does SMA5J6.5-E3/61 meet AEC-Q101 qualification?
The SMA5J6.5-E3/61 itself is RoHS-compliant commercial-grade; however, the HE3-suffixed variant (e.g., SMA5J6.5AHE3/61) is explicitly AEC-Q101 qualified. For automotive applications requiring formal qualification, the HE3 version must be specified-SMA5J6.5-E3/61 shares identical electrical and mechanical characteristics but lacks the certified test report package.
What is the maximum clamping voltage of SMA5J6.5-E3/61 at its rated peak pulse current?
The SMA5J6.5-E3/61 clamps to a maximum of 11.2 V when subjected to its rated 44.6 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet and defines the upper voltage limit imposed on protected circuitry during surge events.
Can SMA5J6.5-E3/61 be used in place of SMA5J6.5A-E3/61?
Yes-SMA5J6.5-E3/61 and SMA5J6.5A-E3/61 share identical electrical specifications (VWM = 6.5 V, VBR = 7.22–7.98 V, VC ≤ 11.2 V, PPPM = 500 W) and DO-214AC packaging. The "A" suffix denotes Vishay's standard marking code (5AK); absence of "A" in the part number does not indicate functional deviation, and both are interchangeable in design.
What is the thermal resistance specification for SMA5J6.5-E3/61?
The SMA5J6.5-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" copper pads per terminal, and a junction-to-lead resistance (RθJL) of 25 °C/W. These values guide thermal pad sizing and airflow requirements to maintain TJ ≤ 150 °C under repetitive surge conditions.
