Product details
Overview
SMAJ60C-E3/61 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 60 V stand-off voltage (VWM), 107 V maximum clamping voltage (VC) at 3.7 A peak pulse current (IPPM), 400 W peak pulse power (10/1000 µs), and operates from −55 °C to +150 °C - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the SMAJ60C-E3/61 datasheet, SMAJ60C-E3/61 pinout, SMAJ60C-E3/61 application, or SMAJ60C-E3/61 equivalent, key selection criteria include bi-directional clamping capability, low leakage (<1 µA at 60 V), RoHS-compliant matte tin terminals, MSL Level 1 rating, and compatibility with automated SMT placement on 5.0 × 5.0 mm copper pads.
Technical Context
This bi-directional TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance. Its symmetrical breakdown behavior ensures identical clamping in both polarities, with VBR min/max of 66.7 V / 81.5 V at 1 mA test current.
The device is rated for 400 W peak pulse power (10/1000 µs waveform) up to 78 V; above that threshold, derated to 300 W per specification. Thermal resistance is 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), supporting reliable operation under repetitive surge conditions when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping initiates |
| VC @ IPPM | 107 V - clamped voltage across device during 3.7 A 10/1000 µs surge, limiting downstream stress |
| IPPM | 3.7 A - peak surge current survivable per single 10/1000 µs pulse under defined thermal conditions |
| PPPM | 400 W - peak pulse power dissipation capability at ≤78 V; confirms robustness against common lightning/ESD transients |
| ID @ VWM | <1 µA - ultra-low reverse leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ Range | −55 °C to +150 °C - wide junction temperature range supports under-hood automotive and industrial ambient environments |
| Package | DO-214AC (SMA) - surface-mount outline with 5.28 mm body length, compatible with standard SMT reflow profiles |
Pinout & Package
DO-214AC (SMA) package: bi-directional device with no polarity marking; two terminals are electrically symmetric and interchangeable. Mounting requires 0.2 × 0.2 inch (5.0 × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Either terminal serves as input/output; bidirectional clamping eliminates orientation constraints during PCB layout |
| Cathode Band (absent) | Polarity indicator | Not present - confirms bi-directional construction; no cathode/anode distinction required in circuit design |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 400 W peak pulse power (≤78 V) | Meets IEC 61000-4-5 Level 3 (1 kV surge) requirements when properly laid out |
| MSL Level 1, 260 °C reflow compatible | Supports lead-free assembly without preconditioning or special handling |
| Glass-passivated junction | Ensures stable breakdown characteristics and long-term reliability under repeated surge stress |
| RoHS-compliant matte tin plating | Guarantees solderability per J-STD-002 and whisker resistance per JESD201 Class 1A |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60CA-E3/61 | Identical electrical specs and packaging; "CA" suffix explicitly denotes bi-directional variant per Vishay naming convention - same as SMAJ60C-E3/61 per datasheet footnote (5). | No functional difference; both intended for symmetric AC or floating DC line protection. | Select SMAJ60CA-E3/61 only if internal BOM or procurement system mandates explicit "CA" suffix alignment. |
| SMBJ60C-E3/52 | Same VWM (60 V) and VC (107 V), but higher PPPM = 600 W (10/1000 µs) and SMB package (DO-214AA) with larger thermal mass. | Better suited for higher-energy threats (e.g., IEC 61000-4-5 Level 4); requires larger PCB footprint and different pad layout. | Choose SMBJ60C-E3/52 when surge energy exceeds 400 W capability or when board space allows larger package for improved thermal margin. |
Compared with SMAJ60C-E3/61, SMAJ60CA-E3/61 offers identical protection performance in the same DO-214AC package, while SMBJ60C-E3/52 provides 50 % higher pulse power in a physically larger package - enabling trade-offs between board area, surge margin, and thermal management in industrial and automotive designs.

FAQ
What is the clamping voltage of SMAJ60C-E3/61 under a standard 10/1000 µs surge?
The SMAJ60C-E3/61 exhibits a maximum clamping voltage (VC) of 107 V when subjected to its rated peak pulse current of 3.7 A using the 10/1000 µs waveform. This value is measured at TA = 25 °C with devices mounted on 0.2 × 0.2 inch copper pads per terminal, ensuring consistent performance in production-relevant thermal conditions. The SMAJ60C-E3/61 maintains this clamping behavior symmetrically in both directions due to its bi-directional construction.
Is SMAJ60C-E3/61 RoHS compliant and suitable for lead-free reflow?
Yes, SMAJ60C-E3/61 is RoHS 2002/95/EC compliant and rated for lead-free reflow with a maximum peak temperature of 260 °C (per J-STD-020 MSL Level 1). Its matte tin-plated leads meet J-STD-002 solderability requirements and JESD201 Class 1A whisker testing. The SMAJ60C-E3/61 can be processed in standard Pb-free reflow ovens without preconditioning or special profile adjustments.
How does SMAJ60C-E3/61 differ from uni-directional SMAJ60A-E3/61?
SMAJ60C-E3/61 is bi-directional with symmetrical clamping in both polarities and no cathode band marking, whereas SMAJ60A-E3/61 is uni-directional, featuring a cathode band and forward voltage drop (~3.5 V at 25 A). The SMAJ60C-E3/61 supports AC-coupled or floating lines (e.g., RS-485, Ethernet), while SMAJ60A-E3/61 is intended for DC-biased unidirectional rails. Their VWM, VC, and PPPM ratings are otherwise identical.
What is the maximum reverse leakage current for SMAJ60C-E3/61 at its stand-off voltage?
The SMAJ60C-E3/61 specifies a maximum reverse leakage current (ID) of 1 µA at its 60 V stand-off voltage (VWM) and TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes standby power loss in battery-operated systems. The SMAJ60C-E3/61 maintains this spec across its full operating temperature range per datasheet characterization.
Can SMAJ60C-E3/61 be used in automotive applications requiring AEC-Q200 qualification?
No - SMAJ60C-E3/61 carries the "E3" commercial-grade suffix and is not AEC-Q200 qualified. For automotive use, specify the "HE3" variant (e.g., SMAJ60CHE3/61), which is AEC-Q101 qualified and rated for high-reliability automotive environments. The SMAJ60C-E3/61 is suitable for industrial and consumer applications but lacks the extended temperature cycling, humidity, and lifetime validation required for automotive grade deployment.
