Product details
Overview
SMA5J6.0C-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 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 10 mA), 500 W peak pulse power (10/1000 μs), 48.5 A peak pulse current (IPPM), and clamps to ≤10.3 V at IPPM. It is used in automotive sensor interface protection and industrial I/O line surge suppression.
For engineers reviewing the SMA5J6.0C-E3/5A datasheet, SMA5J6.0C-E3/5A pinout, SMA5J6.0C-E3/5A application, or SMA5J6.0C-E3/5A equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, RoHS-compliant matte tin plating, and DO-214AC thermal performance with RθJA = 80 °C/W.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<800 μA at VWM), while the low incremental surge resistance enables effective clamping during fast transients such as ESD (IEC 61000-4-2) and EFT (IEC 61000-4-4).
The device is rated for TJ = –55 °C to +150 °C operation and meets AEC-Q101 stress test requirements for automotive use. Its 10/1000 μs waveform rating reflects standardized surge immunity testing per ANSI/IEEE C62.35, and its thermal resistance (RθJL = 25 °C/W) supports reliable power dissipation when mounted on recommended 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse/forward voltage before clamping begins; sets operating margin for protected circuitry. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold range ensuring predictable turn-on under transient stress. |
| IPPM | 48.5 A - Peak surge current it safely diverts during a 10/1000 μs transient without failure. |
| VC @ IPPM | ≤10.3 V - Clamped voltage seen by downstream components; defines maximum stress on protected ICs or MOSFETs. |
| PPPM | 500 W - Peak pulse power handling capacity; determines survivability against high-energy surges like load dump or inductive kick. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments and high-ambient industrial settings. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, bi-directional configuration with no polarity marking (unlike uni-directional variants which feature a cathode band). Molding compound meets UL 94 V-0; terminals are matte tin plated, solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional transient conduction path | No functional distinction between terminals; either terminal serves as anode or cathode depending on transient polarity. |
| Case (body) | Thermal and mechanical interface | DO-214AC body provides mechanical anchoring and contributes to thermal dissipation via PCB copper pad contact. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing - suitable for engine control, ADAS, and body electronics. |
| MSL Level 1 (260 °C peak reflow) | Enables standard SMT assembly without pre-baking; compatible with lead-free reflow profiles per J-STD-020. |
| Glass-passivated junction | Ensures stable VBR tolerance, low leakage drift over time, and resistance to humidity-induced degradation. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a), improving clamping fidelity. |
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 jump-start transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed across signal/power pins to limit transient excursions below IC absolute maximum ratings.

| Consumer Power Adapter Input | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters subjected to lightning-induced surges on DC output rails. IC Role / Device Role / Timing Role: Fast-response clamp across regulated 5 V/12 V outputs to prevent overvoltage propagation to USB ports or downstream SMPS controllers. Use Value: Limits clamped voltage to ≤10.3 V, preserving compliance with USB PD and safety isolation barriers under 10/1000 μs stress. |
Use Scenario: Protecting Ethernet PHYs and DSL line drivers from induced surges on twisted-pair telecom lines. IC Role / Device Role / Timing Role: Bi-directional TVS placed differentially across data pairs to suppress common-mode transients without distorting signal integrity. Use Value: Maintains <1 pF junction capacitance at VWM, minimizing insertion loss and return loss impact on 100 MHz+ signal bandwidths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ6.0CA | Same DO-214AC package, VWM = 6.0 V, VC = 10.3 V, but rated for 400 W PPPM (vs. 500 W); lower IPPM (40 A). | Marginally lower surge handling; acceptable for non-automotive or lower-risk industrial use. | Select if cost sensitivity outweighs need for full 500 W headroom or AEC-Q101 validation. |
| ON Semiconductor 1.5SMC6.0CA | DO-214AB (SMB) package - larger footprint (5.3 mm × 4.1 mm vs. SMA's 4.5 mm × 2.8 mm); same VWM/VC, but higher thermal resistance (RθJA ≈ 100 °C/W). | Requires PCB layout change; less suitable for space-constrained automotive modules. | Choose only when existing SMB footprint is fixed and thermal derating is acceptable. |
Compared with SMA5J6.0C-E3/5A, SMAJ6.0CA offers cost efficiency at reduced surge margin, while 1.5SMC6.0CA trades compactness and thermal performance for broader distributor availability - making SMA5J6.0C-E3/5A optimal for AEC-Q101–mandated, space-limited, high-reliability designs.

FAQ
What does the "C" suffix in SMA5J6.0C-E3/5A indicate?
The "C" in SMA5J6.0C-E3/5A denotes bi-directional functionality - meaning the device provides symmetrical transient suppression in both polarities, unlike uni-directional variants (e.g., SMA5J6.0A) that require correct orientation. This eliminates polarity concerns during placement and simplifies design for AC-coupled or differential signal lines. The SMA5J6.0C-E3/5A is fully characterized for identical VBR, VC, and IPPM in either direction.
Is SMA5J6.0C-E3/5A RoHS compliant and lead-free?
Yes, SMA5J6.0C-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 standards. It also passes JESD 201 Class 1A whisker testing, ensuring long-term interconnect reliability in automated assembly and thermal cycling environments.
What is the maximum clamping voltage of SMA5J6.0C-E3/5A under surge conditions?
The maximum clamping voltage (VC) of SMA5J6.0C-E3/5A is 10.3 V when subjected to its rated peak pulse current (IPPM = 48.5 A) under a 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet and represents the highest voltage downstream components will experience during worst-case transient events - critical for ensuring compatibility with 5 V or 3.3 V logic interfaces.
Can SMA5J6.0C-E3/5A be used in place of a uni-directional TVS like SMA5J6.0A?
No - SMA5J6.0C-E3/5A is bi-directional and lacks polarity marking, whereas SMA5J6.0A is uni-directional with a cathode band. Substituting them requires verifying circuit topology: SMA5J6.0C-E3/5A is appropriate for AC signals or floating nodes, while SMA5J6.0A must be oriented correctly for DC-biased lines. Using SMA5J6.0C-E3/5A in a uni-directional application adds no penalty but forfeits the tighter VF specification (3.5 V at 25 A) available only in uni-directional versions.
What is the thermal resistance of SMA5J6.0C-E3/5A, and how does it affect layout?
SMA5J6.0C-E3/5A has 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. To maintain reliability under repeated surges, PCB layout must replicate this minimum copper area - undersized pads increase junction temperature, accelerating degradation and reducing surge lifetime. The device's RθJL = 25 °C/W further emphasizes the importance of robust thermal connection to the PCB ground plane.
