Product details
Overview
SMA5J7.0C-E3/5A from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-214AC (SMA) package, designed for surge protection on signal and power lines. It features a 7.0 V stand-off voltage (VWM), 12.0 V clamping voltage (VC) at 41.7 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O circuits against ESD and load dump transients.
For engineers reviewing the SMA5J7.0C-E3/5A datasheet, SMA5J7.0C-E3/5A pinout, SMA5J7.0C-E3/5A application, or SMA5J7.0C-E3/5A equivalent, key selection criteria include bi-directional polarity, clamping performance under 41.7 A surge, thermal resistance (RθJA = 80 °C/W), AEC-Q101 qualification, and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This bi-directional TVS diode operates symmetrically in both reverse and forward directions, with breakdown voltage (VBR) specified between 7.78 V and 8.60 V at 10 mA test current. Its low incremental surge resistance enables tight clamping (12.0 V at IPPM), critical for safeguarding downstream ICs during fast transients like ISO 7637-2 pulse 1 and 2b.
Designed for surface-mount automated placement, it uses a glass passivated junction and meets MSL Level 1 (260 °C reflow peak). The DO-214AC package provides mechanical robustness and thermal dissipation capability up to 150 °C junction temperature, supporting automotive-grade reliability requirements.
Key Specifications

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 ISO 16750-2 load dump and ESD events. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed directly at connector entry point to shunt surge energy before reaching protected IC. Use Value: Clamps to 12.0 V at 41.7 A, preventing damage to 5 V or 3.3 V interface ICs while maintaining signal integrity during normal operation. | Use Scenario: Safeguarding digital input/output channels in programmable logic controllers exposed to inductive switching transients from solenoids and relays. IC Role / Device Role / Timing Role: Standoff-rated TVS placed across channel terminals to absorb repetitive 500 W surges without degradation. Use Value: Withstands >1000 surges at rated PPPM and maintains <800 µA leakage at 7.0 V, ensuring long-term reliability in harsh factory environments. |
| Consumer USB Port Protection | Telecom Line Interface Protection |
Use Scenario: Securing USB 2.0 data lines (D+/D−) against human-body-model ESD (±15 kV) and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance bi-directional clamp integrated into USB connector footprint to minimize signal distortion. Use Value: Symmetric clamping ensures equal protection for both differential signals; 12.0 V VC prevents latch-up in USB transceivers during ±8 kV contact discharge. | Use Scenario: Protecting Ethernet PHY interfaces and analog telephony line drivers from lightning-induced surges and AC power cross-talk. IC Role / Device Role / Timing Role: Primary-level surge suppressor mounted at board edge before isolation transformers or line drivers. Use Value: 500 W PPPM rating handles telecom-specific surge waveforms (10/700 µs); DO-214AC footprint allows compact layout near RJ-45 connectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J7.0CAHE3/5A | AEC-Q101 qualified version with HE3 suffix; identical electrical specs but enhanced whisker resistance (JESD 201 Class 2) | Required for automotive safety-critical modules where extended reliability validation is mandated | Select when full AEC-Q101 compliance documentation and whisker testing traceability are contractually required |
| SMCJ7.0CA | Higher PPPM (1500 W), larger DO-214AB (SMC) package, same VWM/VC ratings | Suitable for higher-energy surge environments (e.g., 24 V industrial power rails) where board space permits larger footprint | Choose when system-level surge tests exceed 500 W and thermal mass must be increased without changing circuit topology |
Compared with SMA5J7.0C-E3/5A, the HE3 variant adds whisker-test assurance for automotive deployment, while SMCJ7.0CA trades compactness for 3× surge power headroom - making SMA5J7.0C-E3/5A optimal for space-constrained, cost-sensitive 7 V rail protection where 500 W suffices.

FAQ
What is the polarity configuration of SMA5J7.0C-E3/5A?
SMA5J7.0C-E3/5A is a bi-directional TVS diode, meaning it has no designated anode or cathode - both terminals are functionally identical and symmetrical. Unlike uni-directional variants (e.g., SMA5J7.0A), it lacks a cathode band marking and clamps transients equally in both directions, making it ideal for AC-coupled or floating signal lines such as USB D+/D− or differential sensor outputs.
Does SMA5J7.0C-E3/5A meet automotive qualification standards?
Yes, SMA5J7.0C-E3/5A is AEC-Q101 qualified, as confirmed by Vishay's documentation for the SMA5J5.0A–SMA5J40CA family. This qualification validates its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces, covering stress tests for temperature cycling, humidity, mechanical shock, and surge endurance.
What is the maximum clamping voltage of SMA5J7.0C-E3/5A under surge conditions?
The maximum clamping voltage (VC) of SMA5J7.0C-E3/5A is 12.0 V, measured at its rated peak pulse current (IPPM) of 41.7 A using the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures protected downstream ICs (e.g., 5 V microcontrollers or transceivers) remain within safe voltage limits during transient events.
How does the DO-214AC (SMA) package affect thermal performance of SMA5J7.0C-E3/5A?
The DO-214AC (SMA) package of SMA5J7.0C-E3/5A delivers a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This enables reliable operation up to +150 °C junction temperature in compact layouts, though thermal derating is required above 25 °C ambient per Vishay's Fig. 2.
Is SMA5J7.0C-E3/5A RoHS and halogen-free compliant?
Yes, SMA5J7.0C-E3/5A carries the E3 suffix, indicating full RoHS compliance per EU Directive 2011/65/EU and halogen-free status per JEDEC JS709A. Its matte tin-plated leads meet solderability standards J-STD-002 and JESD 22-B102, and it passes JESD 201 Class 1A whisker testing - verified in Vishay's official documentation for this part number.
