Product details
Overview
SMA5J6.5A-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for robust overvoltage protection on power 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 - deployed in automotive sensor interfaces, industrial I/O modules, and DC power rail protection.
For engineers reviewing the SMA5J6.5A-E3/61 datasheet, SMA5J6.5A-E3/61 pinout, SMA5J6.5A-E3/61 application, or SMA5J6.5A-E3/61 equivalent, key selection criteria include unidirectional polarity, 11.2 V clamping performance at 44.6 A, RoHS-compliant matte tin terminals, MSL Level 1 rating, 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: under normal conditions it presents high impedance (>500 MΩ leakage at 6.5 V), then rapidly avalanches below 11.2 V to divert transients away from downstream ICs. Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance.
Designed for single-pulse 10/1000 μs waveforms per ANSI/IEEE C62.35, it delivers 500 W surge capability with thermal resistance of 80 °C/W (junction-to-ambient) and supports operation from –55 °C to +150 °C - validated per JESD22-B102 solderability and J-STD-020 reflow profiles up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before conduction begins; defines safe operating margin for 5 V–6 V DC rails. |
| VBR min/max | 7.22 V / 7.98 V at 10 mA - tight breakdown window ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | ≤11.2 V at 44.6 A - clamping voltage limits stress on protected MOSFETs or microcontrollers during ESD/EFT events. |
| PPPM | 500 W (10/1000 μs) - sustains high-energy transients from inductive switching or lightning-induced surges without failure. |
| IFSM | 40 A (8.3 ms half-sine) - handles non-repetitive forward surge currents common in automotive load-dump scenarios. |
| TJ max | +150 °C - enables use in under-hood automotive environments and thermally constrained industrial enclosures. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads; polarity indicated by cathode band; meets UL 94 V-0 flammability rating and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to ground or low-impedance return plane; must be routed with minimal inductance for effective clamping. |
| Cathode (banded end) | Reverse-biased terminal / protected line connection | Connected to the line being protected (e.g., 5 V rail or sensor output); avalanche conduction occurs when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Low profile SMA package | Enables high-density PCB layouts and compatibility with standard SMT pick-and-place equipment (0.208" × 0.157", 5.28 mm × 3.99 mm). |
| Glass passivated junction | Ensures long-term stability of VBR and low leakage (<500 μA at VWM), critical for battery-powered or low-power sensor nodes. |
| MSL Level 1 rating | Allows unlimited floor life and reflow at 260 °C peak without baking - simplifies manufacturing for high-volume automotive and industrial production. |
| AEC-Q101 qualification option | HE3/HM3 variants are automotive-qualified; this E3/61 variant is commercial-grade but shares identical die and construction. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between signal line and chassis ground to clamp transients before they reach the transceiver input. Use Value: Clamps to ≤11.2 V at 44.6 A, ensuring protected devices remain within absolute maximum ratings during 500 W surge events. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V DC input lines, absorbing repetitive 10/1000 μs transients induced by inductive switching. Use Value: 6.5 V VWM provides headroom above nominal 5 V logic levels while maintaining fast response (<1 ns) to sub-microsecond spikes. |
| DC Power Rail Protection | Consumer USB Port ESD Suppression |
Use Scenario: Secondary overvoltage protection on 5 V or 12 V DC power distribution networks in embedded systems and power supplies. IC Role / Device Role / Timing Role: Parallel-connected TVS across input capacitor to limit surge voltage during hot-plug or upstream regulator fault conditions. Use Value: 500 W PPPM rating handles high-energy events exceeding IEC 61000-4-5 Level 4 requirements when used with appropriate series impedance. |
Use Scenario: Board-level ESD protection for USB 2.0 data lines and VBUS in portable electronics and docking stations. IC Role / Device Role / Timing Role: Unidirectional TVS on VBUS line to suppress contact discharge (±15 kV) and air discharge (±15 kV) per IEC 61000-4-2. Use Value: Low clamping voltage (≤11.2 V) prevents latch-up or damage to USB controller ICs rated for 5.5 V absolute maximum VDD. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.5A-M3/61 | Halogen-free, RoHS-compliant variant with identical electrical specs and SMA package; same thermal and surge performance. | No functional difference; selected where halogen-free compliance is mandated by OEM or regional environmental regulations. | Choose SMA5J6.5A-M3/61 when halogen-free material content is required; otherwise SMA5J6.5A-E3/61 satisfies standard commercial RoHS needs. |
| SMA6J6.5A-E3/61 | Higher 600 W PPPM rating, same VWM/VBR/VC, larger thermal mass; shares SMA footprint but higher Ippm (48.5 A) and lower RθJA (70 °C/W). | Better suited for harsher surge environments (e.g., heavy industrial motor controls) where margin beyond 500 W is needed. | Select SMA6J6.5A-E3/61 only if design requires >500 W surge headroom; SMA5J6.5A-E3/61 remains optimal for cost-sensitive, space-constrained 500 W applications. |
Compared with SMA5J6.5A-M3/61, the SMA5J6.5A-E3/61 offers identical protection performance with standard RoHS compliance; versus SMA6J6.5A-E3/61, it trades 100 W surge capacity for smaller thermal footprint and lower BOM cost - making it ideal for consumer and mid-tier industrial designs where 500 W is sufficient.

FAQ
What is the clamping voltage of the SMA5J6.5A-E3/61 under rated surge conditions?
The SMA5J6.5A-E3/61 clamps to a maximum of 11.2 V when subjected to its rated 44.6 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is measured at the device terminals under standardized test conditions per ANSI/IEEE C62.35 and is guaranteed across the full operating temperature range of –55 °C to +150 °C. The SMA5J6.5A-E3/61 achieves this with low incremental surge resistance, ensuring consistent protection behavior in real-world surge events.
Is the SMA5J6.5A-E3/61 suitable for automotive applications?
The SMA5J6.5A-E3/61 is commercial-grade and RoHS-compliant but not AEC-Q101 qualified. For automotive use, Vishay offers the SMA5J6.5AHE3_A variant (with HE3 suffix), which shares identical electrical characteristics and SMA packaging but adds AEC-Q101 qualification. The SMA5J6.5A-E3/61 may be used in non-safety-critical automotive subsystems where qualification is not mandated, though design validation per ISO 7637-2 remains the responsibility of the end customer.
What is the meaning of the "-E3/61" suffix in SMA5J6.5A-E3/61?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD22-B102 solderability standards. The "/61" denotes the preferred packaging: 7-inch diameter plastic tape and reel containing 1800 units. This format supports high-speed automated assembly and is compatible with standard SMT feeders. The SMA5J6.5A-E3/61 has a unit weight of 0.064 g and complies with JESD201 Class 2 whisker resistance requirements.
How does the SMA5J6.5A-E3/61 compare to bidirectional TVS diodes like SMA5J6.5CA?
The SMA5J6.5A-E3/61 is unidirectional and intended for DC line protection where polarity is fixed (e.g., VCC-to-ground), offering forward conduction capability and 40 A IFSM rating. In contrast, SMA5J6.5CA is bidirectional, symmetric in both directions, and lacks forward surge rating - suitable for AC or differential signal lines like RS-485. The SMA5J6.5A-E3/61 cannot replace SMA5J6.5CA in bidirectional applications without circuit redesign due to polarity dependence and absence of reverse breakdown symmetry.
What PCB layout guidance applies to the SMA5J6.5A-E3/61 for optimal surge performance?
For optimal transient suppression, the SMA5J6.5A-E3/61 must be mounted on minimum recommended pad layout: 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, with short, wide traces to minimize inductance between the protected line and ground. Thermal relief should be avoided on cathode/anode pads to maintain low RθJA (80 °C/W). Placement must be adjacent to the connector or IC input, not downstream of series impedance, to ensure clamping occurs before voltage overshoot reaches sensitive components.
