Product details
Overview
SMA5J5.0CA-E3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.25 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps transients to ≤9.2 V at 54.3 A IPPM under 10/1000 μs waveform - used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J5.0CA-E3/61 datasheet, SMA5J5.0CA-E3/61 pinout, SMA5J5.0CA-E3/61 application, or SMA5J5.0CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification eligibility (via HE3 suffix), RoHS-compliant matte tin terminations, and thermal resistance (RθJA = 80 °C/W) for surface-mount PCB designs requiring robust ESD and lightning surge immunity.
Technical Context
This bidirectional TVS operates symmetrically across both polarities with identical VBR (6.4–7.25 V), ID ≤800 μA at VWM = 5.0 V, and VC ≤9.2 V at IPPM = 54.3 A. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
The device is rated for TJ = –55 °C to +150 °C, with thermal resistance RθJL = 25 °C/W to leads and RθJA = 80 °C/W on 5.0 mm × 5.0 mm copper pads. It meets ANSI/IEEE C62.35 for transient suppression and is qualified per JESD201 Class 2 for whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse voltage before clamping begins; sets operating margin for 3.3 V/5 V logic and sensor supply rails. |
| VBR min/max | 6.4 V / 7.25 V - guaranteed breakdown range at 10 mA test current; defines minimum trigger threshold and process variation control. |
| VC @ IPPM | ≤9.2 V at 54.3 A - clamping voltage under 10/1000 μs surge; ensures protected ICs see <10 V stress during 500 W transient events. |
| PPPM | 500 W - peak pulse power handling capacity; enables protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges on industrial ports. |
| ID @ VWM | ≤800 μA - reverse leakage at stand-off voltage; low enough to avoid loading 5 V microcontroller inputs or analog sensor outputs. |
| TJ max. | +150 °C - maximum junction temperature; supports operation in under-hood automotive environments and sealed industrial enclosures. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H); matte tin-plated leads compliant with J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional terminal pair | No cathode band; terminals interchangeable - enables single-component protection of AC-coupled or differential signal lines without orientation constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - eliminates need for dual unidirectional devices on balanced lines like RS-485 or CAN bus stubs. |
| Glass-passivated junction | Stable leakage and breakdown over temperature and lifetime - critical for long-term reliability in automotive and industrial deployments. |
| MSL Level 1 | Rated for peak reflow of 260 °C - compatible with standard lead-free SMT assembly without moisture sensitivity concerns. |
| AEC-Q101 qualification path | Available as SMA5J5.0CAHE3_A - enables drop-in use in automotive ECUs where qualification traceability is mandatory. |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|
|
Use Scenario: Protecting ABS wheel speed sensor signal lines from load dump and ISO 7637-2 transients in vehicle chassis harnesses. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between differential pair and PHY IC input pins. Use Value: Limits induced surges to ≤9.2 V while maintaining <800 μA leakage - preserves signal integrity and avoids false triggering in Hall-effect sensors. |
Use Scenario: Safeguarding RS-485 transceivers (e.g., SN65HVD230) on factory floor PLC communication nodes exposed to motor switching noise. IC Role / Device Role / Timing Role: Common-mode transient suppressor across A/B bus lines referenced to ground. Use Value: Absorbs 500 W surges without degradation, enabling compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity requirements. |
| Consumer USB Port ESD | Power Supply Input Stage |
|
Use Scenario: Secondary-level ESD protection on USB 2.0 D+/D– lines downstream of primary TVS arrays in set-top boxes and smart displays. IC Role / Device Role / Timing Role: Fast-response shunt element that activates after primary protection to limit residual voltage to connected PHY. Use Value: Sub-1 ns response and ≤9.2 V clamping prevent latch-up in USB transceivers during ±8 kV contact discharge (IEC 61000-4-2). |
Use Scenario: DC input rail protection (5 V or 12 V) for embedded controllers in HVAC control boards subjected to inductive kickback from relay coils. IC Role / Device Role / Timing Role: Stand-off voltage-aligned shunt clamp placed after bulk filter capacitor and before LDO regulator input. Use Value: 5.0 V VWM matches nominal rail; 500 W PPPM handles repetitive 100 ms surges from 24 V relay back-EMF without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0CA | Lower PPPM (400 W), higher VC (10.8 V at 32.4 A), same VWM/VBR range and SMA package. | Marginally lower surge energy handling; suitable only for sub-Level 3 IEC 61000-4-5 applications. | Select SMAJ5.0CA only when cost sensitivity outweighs need for full 500 W immunity headroom. |
| SMCJ5.0CA | Same electrical specs but in larger SMC (DO-214AB) package; RθJA = 35 °C/W vs. 80 °C/W. | Higher thermal mass enables sustained surge duty cycles; requires 3× PCB area vs. SMA5J5.0CA-E3/61. | Choose SMCJ5.0CA for high-repetition surge environments (e.g., motor drive gate drivers) where board space permits. |
Compared with SMAJ5.0CA and SMCJ5.0CA, SMA5J5.0CA-E3/61 delivers optimal power density: 500 W in the smallest footprint (SMA), enabling compact placement near connectors while maintaining AEC-Q101 upgrade path and industry-standard thermal derating curves.

FAQ
What is the polarity configuration of SMA5J5.0CA-E3/61?
SMA5J5.0CA-E3/61 is a bidirectional TVS diode with symmetrical anode/cathode terminals and no polarity marking. Unlike unidirectional variants (e.g., SMA5J5.0A), it provides identical clamping behavior in both directions - making it ideal for AC-coupled or differential signal lines such as CAN, RS-485, or audio interfaces where voltage reversals occur.
Does SMA5J5.0CA-E3/61 meet AEC-Q101 qualification?
SMA5J5.0CA-E3/61 itself is RoHS-compliant commercial-grade; however, the AEC-Q101 qualified version is designated SMA5J5.0CAHE3_A (with "HE3" suffix and revision code). That variant shares identical electrical specs and package but adds full automotive qualification documentation, traceability, and extended temperature validation - required for under-hood ECU designs.
What is the maximum clamping voltage of SMA5J5.0CA-E3/61 under surge conditions?
The maximum clamping voltage (VC) of SMA5J5.0CA-E3/61 is 9.2 V at a peak pulse current (IPPM) of 54.3 A, tested with a 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures protected downstream ICs remain below absolute maximum ratings during standardized surge events.
How does the thermal performance of SMA5J5.0CA-E3/61 compare to larger package alternatives?
SMA5J5.0CA-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W on 5.0 mm × 5.0 mm copper pads. In contrast, the SMC-packaged SMCJ5.0CA achieves 35 °C/W. While SMA5J5.0CA-E3/61 offers superior power density, its higher RθJA means it requires careful thermal pad design for repeated surge duty cycles - unlike SMCJ5.0CA which better sustains thermal loads.
Can SMA5J5.0CA-E3/61 be used in place of unidirectional TVS diodes like SMA5J5.0A?
No - SMA5J5.0CA-E3/61 is strictly bidirectional and lacks polarity marking, whereas SMA5J5.0A is unidirectional with a cathode band. Substituting SMA5J5.0CA-E3/61 for SMA5J5.0A in DC-biased circuits (e.g., 5 V supply rail protection) may allow forward conduction during normal operation, causing excessive leakage or failure. Always match polarity type to circuit topology.
