Product details
Overview
SMA5J6.5C-E3/5A 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 and 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-E3/5A datasheet, SMA5J6.5C-E3/5A pinout, SMA5J6.5C-E3/5A application, or SMA5J6.5C-E3/5A equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, RoHS-compliant matte tin terminations, MSL Level 1 rating, 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, with electrical characteristics defined identically for forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior, low incremental surge resistance, and fast response time (<1 ns) to ESD and lightning-induced transients.
The device is rated for continuous operation from –55 °C to +150 °C junction temperature and meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C). Thermal resistance is 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), enabling reliable power dissipation under repetitive surge conditions when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse stand-off voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - guaranteed breakdown range ensuring consistent turn-on across production lots |
| VC @ IPPM | 11.2 V at 44.6 A - clamping voltage during 10/1000 µs surge; limits protected circuit stress to safe levels |
| PPPM | 500 W - peak pulse power handling capacity; determines survivability against IEC 61000-4-5 Level 4 surges |
| IPPM | 44.6 A - peak pulse current supported at VC; enables protection of 12 V automotive bus lines |
| TJ max. | +150 °C - maximum junction temperature; supports under-hood automotive deployment without derating |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, bi-directional configuration with no polarity marking. Molding compound meets UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bi-directional terminal pair | No polarity designation; terminals function identically in either direction - simplifies PCB layout and eliminates orientation errors |
| Case (body) | Thermal and mechanical interface | DO-214AC body provides thermal path to PCB copper; requires 5.0 mm × 5.0 mm pad per terminal for rated power dissipation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control and ADAS sensor protection |
| Glass passivated junction | Ensures stable VBR tolerance and long-term parameter stability under thermal stress and humidity exposure |
| MSL Level 1 (260 °C peak) | Enables single-pass lead-free reflow without moisture-related popcorning or delamination |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving system-level immunity |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bi-directional clamping element placed directly at connector entry point to shunt surge energy before reaching sensitive ICs. Use Value: Clamps 10/1000 µs surges up to 500 W while holding VC ≤ 11.2 V - prevents latch-up and damage to 5 V or 3.3 V interface ICs. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and field wiring surges in factory automation environments. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input channels, positioned upstream of optocouplers and level-shifting circuitry. Use Value: Withstands repeated 44.6 A pulses and maintains <1 µA leakage at 6.5 V - preserves signal integrity and reduces false triggering. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Transient suppression on Ethernet PHY power rails and auxiliary bias lines in PoE-powered network switches and base stations. IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), providing fast-response clamping for residual high-frequency surges. Use Value: Fast response time (<1 ns) and low VC ensure downstream DC/DC converters and PHY ICs remain within absolute maximum ratings during combined lightning/surge events. | Use Scenario: Input-stage surge protection in AC/DC adapters for smart home devices, where compact size and bi-directional capability simplify design for dual-polarity input filtering. IC Role / Device Role / Timing Role: Stand-off clamping device across bulk capacitor inputs to absorb line-to-line and line-to-ground transients per IEC 61000-4-5. Use Value: DO-214AC footprint enables high-density layout; RoHS-compliant E3 termination supports automated assembly without whisker risk (JESD 201 Class 1A). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.5CAHE3/5A | AEC-Q101 qualified version with HE3 suffix; identical electrical specs but enhanced reliability screening for automotive use | Required for ASIL-B or higher automotive subsystems; not necessary for commercial/industrial grade designs | Select SMA5J6.5CAHE3/5A only when AEC-Q101 certification is mandated by OEM or functional safety requirements |
| SMCJ6.5CA | Higher PPPM (1500 W), larger DO-214AB (SMC) package, same VWM/VC values | Used where higher surge energy handling is needed (e.g., main power rail protection), but requires larger PCB area | Choose SMCJ6.5CA if system-level surge testing exceeds 500 W or if thermal budget allows larger footprint |
Compared with SMA5J6.5C-E3/5A, SMA5J6.5CAHE3/5A adds automotive qualification without changing clamping performance, while SMCJ6.5CA trades compactness for 3× higher surge power - making SMA5J6.5C-E3/5A optimal for space-constrained, cost-sensitive, and AEC-Q101-optional applications.

FAQ
What does the "C" in SMA5J6.5C-E3/5A indicate?
The "C" suffix denotes bi-directional functionality - meaning SMA5J6.5C-E3/5A provides symmetrical clamping in both polarities, unlike uni-directional variants (e.g., SMA5J6.5A). This eliminates polarity marking on the DO-214AC body and simplifies layout for AC-coupled or floating signal lines.
Is SMA5J6.5C-E3/5A RoHS compliant and lead-free?
Yes, SMA5J6.5C-E3/5A is RoHS compliant and lead-free. The "E3" suffix confirms compliance with Directive 2011/65/EU, and its matte tin-plated leads meet J-STD-002 solderability requirements and JESD 201 Class 1A whisker resistance standards.
What is the maximum clamping voltage of SMA5J6.5C-E3/5A under surge conditions?
The maximum clamping voltage (VC) of SMA5J6.5C-E3/5A is 11.2 V at 44.6 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is guaranteed across temperature and ensures protected ICs remain within safe operating voltage limits during standardized surge events.
Can SMA5J6.5C-E3/5A be used in automotive applications?
Yes, SMA5J6.5C-E3/5A is AEC-Q101 qualified and rated for junction temperatures up to +150 °C, making it suitable for under-hood and cabin automotive applications such as sensor interface protection, infotainment power rails, and body control module I/O conditioning.
How does SMA5J6.5C-E3/5A differ from SMA5J6.5A?
SMA5J6.5C-E3/5A is bi-directional with no polarity marking and identical electrical behavior in both directions, whereas SMA5J6.5A is uni-directional with a cathode band and conducts only in reverse bias. SMA5J6.5C-E3/5A is preferred for AC signals or floating nodes; SMA5J6.5A suits DC-biased lines requiring unidirectional crowbar action.
