Product details
Overview
SMA6J6.0A-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.7–7.41 V breakdown voltage (VBR at 10 mA), 9.5 V maximum clamping voltage at 63.2 A (10/1000 µs), 600 W peak pulse power rating, and operates across –55 °C to +150 °C junction temperature range - deployed in DC power rail protection for industrial sensor interfaces.
For engineers reviewing the SMA6J6.0A-E3/61 datasheet, SMA6J6.0A-E3/61 pinout, SMA6J6.0A-E3/61 application, or SMA6J6.0A-E3/61 equivalent, key selection criteria include clamping voltage under 63.2 A surge, unidirectional polarity compatibility with grounded-cathode layouts, thermal resistance (RθJA = 120 °C/W), RoHS-compliant matte tin terminations, and MSL Level 1 moisture sensitivity for reflow compatibility.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (6.7–7.41 V), it avalanches to limit transient energy by diverting surge current to ground. Its low dynamic resistance (0.033 Ω) ensures tight clamping control during 10/1000 µs surges up to 63.2 A.
The device is optimized for PCB-level protection of 5 V–6 V systems - including microcontroller I/O rails, MOSFET gate drivers, and analog sensor supply lines - where fast response (<1 ns), low leakage (<600 µA at 6.0 V), and stable VBR temperature coefficient (5.9 × 10⁻⁴ /°C) are critical for reliability under thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before conduction begins; matches standard 5 V logic supply rails with margin. |
| VBR (min/max) | 6.7 V / 7.41 V at 10 mA - defines guaranteed avalanche onset window; ensures consistent turn-on across production lots and temperature. |
| VC at IPP | 9.5 V at 63.2 A (10/1000 µs) - clamping voltage seen by protected circuit during worst-case surge; stays below 10 V to safeguard 6 V-tolerant ICs. |
| PPPM (10/1000 µs) | 600 W - peak transient energy absorption capability; supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge immunity on 24 V input lines. |
| ID at VWM | 600 µA max - low leakage preserves battery life and avoids false triggering in high-impedance sensor bias networks. |
| RθJA | 120 °C/W - thermal resistance from junction to ambient on standard 5 mm × 5 mm copper pads; dictates derating above 50 °C ambient. |
| Polarity | Unidirectional - cathode-banded configuration requires correct orientation for DC rail protection; not suitable for AC line or bidirectional data lines. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; connected to protected line side in unidirectional clamp configuration. | When used for positive-rail protection, Anode connects to the line being protected (e.g., +6 V supply); Cathode ties to ground. |
| Cathode | Current exit terminal during reverse avalanche; marked by color band; referenced to system ground. | Ground-reference node for clamping action; must be routed with low-inductance path to minimize voltage overshoot during fast transients. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping performance | 9.5 V VC at 63.2 A (10/1000 µs) enables robust protection of 6 V-rated ICs without overvoltage stress. |
| Thermal reliability | Rated for TJ up to +150 °C and MSL Level 1 handling - supports lead-free reflow (260 °C peak) without popcorn failure. |
| Leakage control | 600 µA max ID at VWM minimizes standby current drain in battery-powered sensor nodes and IoT edge devices. |
| Mounting compatibility | SMA footprint aligns with automated pick-and-place equipment; standardized pad layout (5 mm × 5 mm per terminal) ensures repeatable thermal performance. |
| Material compliance | E3 suffix denotes RoHS-compliant, industrial-grade construction with halogen-free options available (M3 suffix). |
Applications
| Industrial Sensor Power Protection | Automotive Body Control Module Inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J6.0A-M3/61 | Halogen-free, RoHS-compliant variant with identical electrical specs and thermal performance; same SMA package and marking code 6AG. | No functional difference; selected where halogen-free material compliance is mandated by end-equipment environmental standards (e.g., EU EcoDesign). | Choose SMA6J6.0A-M3/61 when halogen-free bill-of-materials is required; otherwise SMA6J6.0A-E3/61 satisfies standard industrial RoHS needs. |
| SMC6J6.0A-E3/73 | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package; higher PPPM (1500 W @ 10/1000 µs), lower RθJA (65 °C/W), and 100 A IPPM rating. | Used where higher surge energy handling (>600 W) or improved thermal dissipation is needed - e.g., 24 V industrial power inputs or outdoor telecom enclosures. | Select SMC6J6.0A-E3/73 only if design requires >600 W surge rating or lower thermal resistance; SMA6J6.0A-E3/61 remains optimal for space-constrained 6 V rail protection. |
Compared with SMA6J6.0A-M3/61, the E3/61 variant offers identical protection performance with standard RoHS compliance; versus SMC6J6.0A-E3/73, the SMA version trades surge capacity and thermal headroom for 40 % smaller PCB footprint - making it ideal for dense sensor node layouts where board area is constrained.

FAQ
What is the maximum clamping voltage of the SMA6J6.0A-E3/61 under a 10/1000 µs surge?
The SMA6J6.0A-E3/61 has a maximum clamping voltage (VC) of 9.5 V when subjected to a 63.2 A peak pulse current with a 10/1000 µs waveform. This value is measured at TA = 25 °C on standard 5 mm × 5 mm copper pads and ensures protected circuits remain within safe voltage margins during common surge events such as inductive load switching.
Is the SMA6J6.0A-E3/61 suitable for bidirectional signal line protection?
No, the SMA6J6.0A-E3/61 is a unidirectional TVS diode and is not suitable for bidirectional signal line protection. Its cathode-band marking and electrical characteristics are specified only for reverse-biased operation. For AC or bidirectional data lines like RS-485 or USB D+/D−, a bidirectional variant such as SMA6J6.0CA-E3/61 would be required instead of the SMA6J6.0A-E3/61.
What is the leakage current specification for SMA6J6.0A-E3/61 at its stand-off voltage?
The SMA6J6.0A-E3/61 exhibits a maximum reverse leakage current (ID) of 600 µA at its 6.0 V stand-off voltage (VWM) and TA = 25 °C. This low leakage supports energy-sensitive applications such as battery-powered sensors and ensures minimal impact on high-impedance bias networks upstream of protected ICs.
Does the SMA6J6.0A-E3/61 meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, the SMA6J6.0A-E3/61 meets MSL Level 1 per J-STD-020, with a maximum lead-free reflow peak temperature of 260 °C. This allows uncomplicated use in standard automated assembly processes without dry-packaging or floor-life restrictions - a key advantage for high-volume manufacturing of industrial and consumer electronics using the SMA6J6.0A-E3/61.
How does the thermal resistance of SMA6J6.0A-E3/61 affect its power derating?
The SMA6J6.0A-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 5 mm × 5 mm copper pads. At TA = 50 °C, its power dissipation rating drops to 4.0 W; above that ambient, linear derating applies - for example, at 75 °C ambient, usable PD reduces to ~2.0 W. Proper PCB copper area is essential to maintain SMA6J6.0A-E3/61 reliability under sustained surge conditions.
