Product details
Overview
SMA5J6.5C-E3/61 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on signal or power lines. It features a 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), 44.6 A peak pulse current (IPPM), and 11.2 V maximum clamping voltage (VC) - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMA5J6.5C-E3/61 datasheet, SMA5J6.5C-E3/61 pinout, SMA5J6.5C-E3/61 application, or SMA5J6.5C-E3/61 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage performance (<1.0 µA at VWM) and fast response time (<1 ns), critical for suppressing ESD and inductive switching spikes.
The device delivers 500 W surge handling per 10/1000 µs waveform under derated conditions up to +150 °C junction temperature, with thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W - supporting reliable operation in compact, thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum reverse stand-off voltage before conduction; defines safe operating window for protected circuitry |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - guaranteed breakdown threshold ensuring consistent clamping onset across production lots |
| VC @ IPPM | 11.2 V at 44.6 A - clamped voltage during 500 W transient; limits stress on downstream ICs like microcontrollers or transceivers |
| IPPM | 44.6 A - peak surge current capacity under standard 10/1000 µs waveform; validates robustness against ISO 7637-2 Pulse 1/2a/5a |
| TJ max. | +150 °C - maximum junction temperature; enables use in under-hood automotive environments and industrial enclosures |
| MSL Level | Level 1 (J-STD-020) - no floor life limitation or bake requirement prior to reflow; simplifies SMT manufacturing flow |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including HTOL, TC, and ESD testing per AEC specification |
Pinout & Package
DO-214AC (SMA) surface-mount package: molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-020 and JESD 22-B102; no polarity marking (bi-directional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | No functional distinction between terminals; either end connects to protected line, other to ground or reference plane |
| Case (exposed lead frame) | Thermal and electrical connection | Integral heat-sinking path to PCB copper; contributes to RθJL = 25 °C/W performance |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded sensor outputs without polarity concerns |
| Glass-passivated junction | Ensures low and stable reverse leakage (<1.0 µA at VWM) over temperature and lifetime, critical for low-power sensor nodes |
| AEC-Q101 qualification | Validates suitability for automotive applications including body control modules, ADAS camera interfaces, and infotainment I/O protection |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients, improving margin for 3.3 V or 5 V logic-level components |
| MSL Level 1 compliance | Eliminates pre-reflow baking and floor-life tracking, reducing manufacturing overhead in high-volume SMT lines |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and jump-start transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed between signal line and chassis ground, responding within <1 ns to limit excursion beyond 11.2 V.

| Consumer USB Port Protection | Telecom Line Interface |
Use Scenario: Guarding USB 2.0 D+/D− lines in set-top boxes and smart displays against ESD events per IEC 61000-4-2 ±15 kV contact discharge. IC Role / Device Role / Timing Role: Low-capacitance bi-directional clamp (CJ ≈ 100 pF at 0 V) placed adjacent to connector, clamping both polarities equally. Use Value: Maintains signal rise/fall times <1 ns while suppressing ESD-induced latch-up in USB PHYs without data corruption. | Use Scenario: Protecting Ethernet PHY magnetics and RJ-45 interface circuits in VoIP phones and small-cell base stations from lightning-induced surges. IC Role / Device Role / Timing Role: Primary surge suppression stage on twisted-pair lines, coordinated with gas discharge tubes for multi-stage protection. Use Value: Absorbs first 500 W of surge energy (10/1000 µs) to prevent saturation of downstream GDTs and ensure system-level immunity to ITU-T K.20/21. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.5CAHE3/61 | AEC-Q101 qualified variant with identical electrical specs; HE3 suffix denotes whisker test class 2 compliance | Required for automotive safety-critical modules where enhanced metallurgical reliability is mandated (e.g., ASIL-B) | Select SMA5J6.5CAHE3/61 when AEC-Q101 qualification is contractually required and class 2 whisker resistance is specified |
| SMCJ6.5CA | Higher 1500 W PPPM rating in larger DO-214AB (SMC) package; same VWM/VC but 128 A IPPM | Suitable for higher-energy threats (e.g., ISO 7637-2 Pulse 5b); requires larger PCB footprint and thermal relief | Choose SMCJ6.5CA when surge threat level exceeds 500 W or when board layout allows DO-214AB footprint |
Compared with SMA5J6.5C-E3/61, SMA5J6.5CAHE3/61 adds whisker-test assurance without electrical trade-offs, while SMCJ6.5CA trades compact size for 3× surge energy handling - making the original optimal for space-constrained AEC-Q101-compliant designs needing 500 W protection.

FAQ
What is the polarity configuration of SMA5J6.5C-E3/61?
SMA5J6.5C-E3/61 is a bi-directional TVS diode with symmetrical terminal behavior - neither end is marked as anode or cathode. This allows it to clamp voltage transients regardless of polarity, making it ideal for protecting AC-coupled lines, differential buses, or ungrounded sensor outputs without orientation constraints during assembly.
Does SMA5J6.5C-E3/61 meet automotive reliability standards?
Yes, SMA5J6.5C-E3/61 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and ESD per JS-001. Its construction - glass-passivated junction, DO-214AC package, and matte tin plating - supports operation in automotive under-hood environments up to +150 °C junction temperature.
What is the maximum clamping voltage of SMA5J6.5C-E3/61 during a 500 W transient?
The maximum clamping voltage (VC) of SMA5J6.5C-E3/61 is 11.2 V at 44.6 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value ensures protected ICs - such as 5 V microcontrollers or CAN transceivers - remain within their absolute maximum voltage ratings during surge events.
Is SMA5J6.5C-E3/61 compatible with lead-free reflow processes?
Yes, SMA5J6.5C-E3/61 is RoHS-compliant (E3 suffix) and rated for lead-free reflow with a maximum peak temperature of 260 °C per J-STD-020. It meets MSL Level 1, meaning it can be stored indefinitely at ambient conditions and placed directly into reflow without baking or moisture sensitivity concerns.
How does the thermal performance of SMA5J6.5C-E3/61 affect PCB layout?
SMA5J6.5C-E3/61 has RθJA = 80 °C/W and RθJL = 25 °C/W, indicating efficient heat transfer to PCB copper. To maintain reliability, mount it on minimum recommended 5.0 mm × 5.0 mm copper pads per terminal - this layout ensures junction temperature stays within the +150 °C limit during repeated 500 W surges.
