Product details
Overview
SMCJ9.0A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, with 9.0 V standoff voltage (VWM), 10.0–11.1 V breakdown voltage (VBR at 1 mA), and 1500 W peak pulse power (10/1000 µs). It clamps transients to ≤15.4 V at 97.4 A peak surge current and operates from –55 °C to +150 °C, protecting MOSFETs and ICs in automotive power rails.
For engineers reviewing the SMCJ9.0A-E3/57T datasheet, SMCJ9.0A-E3/57T pinout, SMCJ9.0A-E3/57T application, or SMCJ9.0A-E3/57T equivalent, key selection criteria include unidirectional polarity, 15.4 V clamping voltage at rated IPPM, RoHS-compliant matte tin plating, MSL Level 1 rating, and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ps) to ESD and lightning-induced surges. Its low incremental surge resistance and high peak pulse current capability (97.4 A) enable robust protection of 12 V automotive and industrial DC bus lines without sacrificing signal integrity.
The device operates in avalanche mode above VBR, delivering stable clamping across temperature (0.074 %/°C VBR tempco) and maintaining <10 µA leakage at 9.0 V. Mounted on 8.0 mm × 8.0 mm copper pads, it achieves 75 °C/W junction-to-ambient thermal resistance under standard conditions.
Key Specifications

|---|---|
| Low-profile SMC package | Enables automated placement and fits space-constrained PCB layouts (max height 3.20 mm) |
| Glass-passivated junction | Ensures long-term reliability and stable VBR performance under thermal cycling and humidity |
| MSL Level 1 rating | Allows unlimited floor life and reflow compatibility up to 260 °C peak without baking |
| RoHS-compliant matte tin leads | Guarantees solderability per J-STD-002 and whisker resistance per JESD 201 Class 2 |
| AEC-Q101 qualification path | HE3 suffix variants meet automotive-grade stress testing requirements for powertrain and body electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A-E3/52T | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VWM/VC specs | Suitable for lower-energy surges or space-limited consumer designs where 1500 W headroom is unnecessary | Select when board area is constrained and surge threat level is ≤600 W (e.g., USB port protection) |
| 1.5SMC9.0A | Same SMC package and electrical specs but non-RoHS, legacy Vishay part with different tape/reel packaging | Acceptable for industrial legacy systems requiring identical form-fit-function but no RoHS compliance | Choose only if RoHS exemption applies and traceability to original 88394 spec sheet is confirmed |
Compared with SMBJ9.0A-E3/52T and 1.5SMC9.0A, SMCJ9.0A-E3/57T delivers higher surge robustness in a RoHS-compliant, MSL Level 1–qualified package-critical for automotive and high-reliability industrial deployments where 1500 W clamping margin and process compatibility are mandatory.

FAQ
What is the clamping voltage of the SMCJ9.0A-E3/57T under maximum rated surge current?
The SMCJ9.0A-E3/57T clamps to a maximum of 15.4 V when subjected to its rated peak pulse current of 97.4 A (10/1000 µs waveform). This value is measured at the device terminals under standard test conditions with 8.0 mm × 8.0 mm copper pads per terminal, ensuring predictable overvoltage limiting for downstream components in the SMCJ9.0A-E3/57T protection circuit.
Is the SMCJ9.0A-E3/57T suitable for automotive applications?
Yes-the SMCJ9.0A-E3/57T is RoHS-compliant and manufactured to Vishay's commercial-grade specifications; AEC-Q101 qualified versions are available under the HE3 suffix (e.g., SMCJ9.0AHE3_A/H). While the -E3/57T itself is not pre-qualified, its construction, thermal rating (TJ max = 150 °C), and electrical parameters align with automotive power rail protection requirements when validated per customer qualification protocols.
What does the "E3/57T" suffix indicate in SMCJ9.0A-E3/57T?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "57T" specifies packaging in 7-inch plastic tape-and-reel format with 850 units per reel. This ordering code ensures consistent assembly-line compatibility, J-STD-020 MSL Level 1 handling, and traceable lot control for the SMCJ9.0A-E3/57T in high-volume manufacturing.
How does the SMCJ9.0A-E3/57T differ from bidirectional SMCJ9.0CA variants?
The SMCJ9.0A-E3/57T is unidirectional, featuring a cathode band and conducting only in reverse avalanche mode; SMCJ9.0CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. Their VWM (9.0 V), VBR, and VC values are identical, but SMCJ9.0A-E3/57T must be oriented correctly on PCB, whereas SMCJ9.0CA simplifies layout for AC-coupled or floating lines-key distinction for SMCJ9.0A-E3/57T system integration.
What is the maximum leakage current of the SMCJ9.0A-E3/57T at its standoff voltage?
At its rated standoff voltage of 9.0 V and TA = 25 °C, the SMCJ9.0A-E3/57T exhibits a maximum reverse leakage current (ID) of 10 µA. This low leakage ensures minimal power loss in always-on circuits and avoids false triggering in high-impedance sensing nodes, supporting stable operation across the full –55 °C to +150 °C junction temperature range of the SMCJ9.0A-E3/57T.
