Product details
Overview
SMA5J6.0A-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 10 mA), 10.3 V clamping voltage (VC) at 48.5 A peak pulse current, and 500 W peak pulse power rating with 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients.
For engineers reviewing the SMA5J6.0A-E3/61 datasheet, SMA5J6.0A-E3/61 pinout, SMA5J6.0A-E3/61 application, or SMA5J6.0A-E3/61 equivalent, key selection criteria include clamping performance under 48.5 A surge, thermal resistance (RθJA = 80 °C/W), RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 6.0 V, it avalanches at VBR ≥ 6.67 V and clamps to ≤ 10.3 V at 48.5 A, limiting energy dissipation to 500 W for 10/1000 μs transients. Its glass-passivated junction ensures stable leakage (< 800 μA at VWM) and fast response time (< 1 ns).
Rated for -55 °C to +150 °C junction temperature, it uses a low-profile SMA (DO-214AC) package with MSL Level 1 moisture sensitivity and J-STD-002/JESD 22-B102 solderability compliance. Polarity is marked by a cathode band; no marking on bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.0 V - maximum continuous reverse operating voltage before significant conduction begins; sets threshold for normal operation without leakage penalty. |
| VBR (Breakdown Voltage) | 6.67–7.37 V at 10 mA - guaranteed avalanche initiation range; ensures reliable triggering above system nominal voltage. |
| VC (Clamping Voltage) | 10.3 V at IPPM = 48.5 A - peak voltage seen by protected circuit during worst-case 500 W transient; defines safe margin for downstream components. |
| PPPM (Peak Pulse Power) | 500 W (10/1000 μs) - maximum transient energy absorption capability; determines survivability against common lightning/inductive-spike waveforms. |
| IFSM (Surge Current) | 40 A (8.3 ms half-sine) - unidirectional forward surge rating; validates robustness during power-rail fault events like hot-plug or load dump. |
| TJmax | +150 °C - maximum junction temperature; enables use in high-ambient industrial and automotive under-hood environments. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads. Cathode indicated by a single band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to system ground or lower-potential rail; forms shunt path during overvoltage events. |
| Cathode | Reverse voltage input / Clamping node | Connected to protected line (e.g., 5 V rail or sensor output); conducts avalanche current to anode when VREV > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Low incremental surge resistance | Enables tight clamping (VC − VBR ≈ 3.6 V), minimizing voltage overshoot during fast transients. |
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without preconditioning; eliminates moisture-related popcorning risk. |
| AEC-Q101 qualification option (HE3/HM3) | Validates suitability for automotive electronics where TVS failure could impact functional safety. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 5 V microcontroller supply rails in engine control units exposed to ISO 7637-2 pulse 1 and pulse 2b transients. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between VCC and GND, clamping negative-going spikes and positive load-dump surges. Use Value: Limits rail voltage to ≤10.3 V during 48.5 A transients, preventing latch-up or permanent damage to 5 V logic ICs. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA transmitter) from ESD and inductive kickback in factory automation PLC modules. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, referenced to local ground, absorbing sub-μs ESD events per IEC 61000-4-2 Level 4. Use Value: Sub-1 ns response and <800 μA leakage at 6.0 V preserve signal integrity while enabling fail-safe operation in harsh noise environments. |
| Consumer USB Power Input Protection | Telecom DC Feeder Line Protection |
Use Scenario: Overvoltage suppression on 5 V USB Type-A power inputs in set-top boxes subjected to accidental 12 V adapter misconnection. IC Role / Device Role / Timing Role: Primary shunt clamp on VBUS line, coordinated with upstream fuse and secondary filtering. Use Value: 500 W rating handles sustained overvoltage without thermal runaway; RoHS-compliant E3 suffix meets global regulatory requirements. |
Use Scenario: Secondary protection on -48 V telecom DC feeder lines entering remote radio units, complementing primary gas discharge tube (GDT) stages. IC Role / Device Role / Timing Role: Fast-response TVS bridging feed line to chassis ground, suppressing fast-rising transients missed by slower GDTs. Use Value: Low RθJA = 80 °C/W allows mounting on minimal copper area; 150 °C TJmax supports operation in sealed outdoor enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ6.0A | Same SMA package, identical VWM = 6.0 V and PPPM = 400 W (lower than SMA5J6.0A-E3/61's 500 W); VC = 10.5 V at 43.5 A. | Suitable for lower-energy transients; may require derating in high-surge environments like automotive load dump. | Select SMA5J6.0A-E3/61 when 500 W headroom and tighter clamping (10.3 V vs. 10.5 V) are critical for sensitive 5 V logic. |
| ON Semiconductor 1.5SMC6.0A | DO-214AB (SMB) package - larger footprint (4.58 mm × 3.94 mm vs. SMA's 4.50 mm × 2.79 mm); same VWM, VBR, and PPPM = 500 W. | Requires PCB layout change; better thermal dissipation (RθJA ≈ 60 °C/W) but incompatible with space-constrained designs. | Choose SMA5J6.0A-E3/61 for high-density layouts where SMA's smaller DO-214AC footprint and automated placement compatibility are prioritized. |
Compared with SMAJ6.0A and 1.5SMC6.0A, the SMA5J6.0A-E3/61 delivers superior power density (500 W in smallest outline), tighter clamping, and verified MSL Level 1 reflow compatibility - making it optimal for miniaturized, high-reliability DC rail protection where board space and surge margin are constrained.

FAQ
What is the clamping voltage of the SMA5J6.0A-E3/61 under maximum rated surge current?
The SMA5J6.0A-E3/61 clamps to a maximum of 10.3 V at its rated peak pulse current of 48.5 A (10/1000 μs waveform). This value is measured and guaranteed per Vishay's datasheet Document Number 88875, ensuring predictable overvoltage limiting for protected circuits downstream of the SMA5J6.0A-E3/61.
Is the SMA5J6.0A-E3/61 RoHS-compliant and suitable for lead-free reflow?
Yes, the SMA5J6.0A-E3/61 carries the "E3" suffix indicating RoHS-compliance and qualification for lead-free reflow up to 260 °C peak temperature (MSL Level 1 per J-STD-020). Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, making it compatible with standard SMT assembly processes.
Does the SMA5J6.0A-E3/61 have automotive qualification?
The base SMA5J6.0A-E3/61 is commercial-grade; however, the automotive-qualified variant is SMA5J6.0AHE3_A (with "HE3" suffix), which is AEC-Q101 qualified. The HE3 version shares identical electrical specs but adds stress testing for temperature cycling, humidity, and mechanical shock required in automotive ECUs and ADAS modules.
What is the maximum reverse leakage current of the SMA5J6.0A-E3/61 at its stand-off voltage?
At VWM = 6.0 V and TA = 25 °C, the SMA5J6.0A-E3/61 exhibits a maximum reverse leakage current (ID) of 800 μA. This low leakage preserves power efficiency in always-on systems and avoids false triggering in high-impedance sensing nodes protected by the SMA5J6.0A-E3/61.
How does the SMA5J6.0A-E3/61 differ from bidirectional variants like SMA5J6.0CA?
The SMA5J6.0A-E3/61 is unidirectional and features a cathode band for polarity identification; it blocks forward current and clamps only reverse overvoltages. In contrast, SMA5J6.0CA is bidirectional with symmetrical clamping in both directions and no polarity marking - used where AC signals or dual-polarity transients require protection without regard to DC bias direction.
