Product details
Overview
3.0SMCJ6.5A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 6.5V reverse standoff voltage (VRWM), 7.22–7.98V breakdown voltage (VBR) at 10mA, 11.2V max clamping voltage (VC) at 267.9A peak pulse current (IPP), and IEC-61000-4-2 ESD rating of 30kV (air/contact). It is used in industrial power supplies to safeguard downstream regulators and microcontrollers against lightning-induced surges.
For engineers reviewing the 3.0SMCJ6.5A-13 datasheet, 3.0SMCJ6.5A-13 pinout, 3.0SMCJ6.5A-13 application, or 3.0SMCJ6.5A-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, peak pulse current handling under 10/1000μs waveform, thermal derating above +25°C ambient, and SMC package solderability per MIL-STD-202.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias (≤6.5V), it draws ≤500µA leakage; when transient exceeds VBR (7.22–7.98V), it avalanches to clamp voltage at ≤11.2V while diverting up to 267.9A (10×1000μs pulse). Its glass-passivated junction ensures stable breakdown and low capacitance.
It is rated for -55°C to +150°C operating junction temperature, complies with JEDEC high-reliability standards, and is RoHS-compliant with halogen- and antimony-free "Green" construction. The cathode band identifies polarity on the SMC package top view.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000μs transients without failure |
| Reverse Standoff Voltage | 6.5V - maximum continuous DC voltage before significant leakage |
| Breakdown Voltage | 7.22–7.98V @ 10mA - precise avalanche initiation threshold for predictable clamping onset |
| Max Clamping Voltage | 11.2V @ 267.9A - limits voltage seen by protected circuit during worst-case surge |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - withstands human-body and contact discharge events |
| Junction Temp Range | -55°C to +150°C - supports operation in automotive engine bays and industrial enclosures |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with matte tin-plated leads; moisture sensitivity level 1 per J-STD-020; weight ≈0.21g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node in unidirectional configuration |
| Cathode | High-side surge input terminal | Marked with cathode band; connects to protected line (e.g., 5V rail or RS-485 bus) |
Key Features
| Feature | Design Value |
|---|---|
| 3000W peak pulse rating | Enables robust protection against IEC 61000-4-5 Level 4 surges (4kV/2Ω) on 12V/24V systems |

| Lead-free & RoHS-compliant | Meets EU Directive 2015/863/EU with <900ppm Br/Cl and <1000ppm Sb - suitable for green manufacturing |
| Low clamping ratio (VC/VBR ≈ 1.47) | Delivers tight voltage limiting - critical for protecting 3.3V/5V logic with minimal headroom margin |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed upstream of DC-DC converter input capacitor.

Use Scenario: Half-duplex RS-485 transceiver interface on factory automation sensor node. IC Role / Device Role / Timing Role: Bidirectional protection (using 3.0SMCJ6.5CA variant) across A/B differential pair and GND.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A (Diodes Inc.) | Same VRWM/VBR/VC specs but 600W rating (vs. 3000W); SMB package (smaller footprint, lower thermal mass) | Suitable only for lower-energy transients (e.g., HBM ESD), not IEC 61000-4-5 surges | Select when board space is constrained and surge threat level is limited to ESD-only environments |
| 1.5SMCJ6.5A (ON Semiconductor) | Identical 3000W rating, 6.5V VRWM, and SMC package; minor VBR tolerance (7.22–8.00V vs. 7.22–7.98V) and higher IR (1000µA vs. 500µA) | Functionally interchangeable in most 24V industrial designs; requires validation of leakage impact on high-impedance bias networks | Choose for dual-sourcing where Diodes' supply chain constraints exist; verify clamping consistency in final layout |
Compared with SMBJ6.5A, the 3.0SMCJ6.5A-13 delivers 5× higher surge energy handling in the same SMC footprint; versus 1.5SMCJ6.5A, it offers tighter leakage control critical for battery-backed or low-quiescent circuits.

FAQ
What is the maximum allowable PCB trace length between 3.0SMCJ6.5A-13 and the protected IC?
Trace inductance directly impacts clamping performance: for optimal protection, keep total trace length (anode-to-ground + cathode-to-line) under 10mm. Longer traces increase voltage overshoot during fast transients (e.g., ESD), potentially exceeding the protected IC's absolute maximum rating despite the TVS's 11.2V clamping spec.
Does 3.0SMCJ6.5A-13 require a heatsink for continuous operation?
No heatsink is required under normal conditions because the device handles only non-repetitive transients (max 4 pulses/minute per datasheet). However, its 3000W rating assumes mounting on 8.00mm² copper land areas; reducing pad size below this de-rates peak power and may cause thermal runaway during repeated surges.
Can 3.0SMCJ6.5A-13 be used in bidirectional configurations?
No - 3.0SMCJ6.5A-13 is unidirectional and features a cathode band. For bidirectional protection (e.g., AC lines or differential buses), use the pin-compatible 3.0SMCJ6.5CA-13 variant, which has symmetrical breakdown in both polarities and no polarity marking.
How does the 500µA max reverse leakage at VRWM affect low-power battery applications?
At 6.5V standoff, 500µA leakage adds negligible drain in most systems (e.g., 0.013% of a 3.8Ah Li-ion cell's capacity per year), but becomes critical in multi-year coin-cell-powered IoT sensors - in such cases, verify system quiescent current budget allows for this fixed leakage path across all operating temperatures.
