Product details
Overview
3.0SMCJ36CA-13 from Diodes Incorporated is a bi-directional 3000W surface-mount transient voltage suppressor (TVS) designed for robust overvoltage protection in DC power rails and signal lines. It features a 36V reverse standoff voltage (VRWM), 40.0–44.2V breakdown voltage (VBR), 58.1V maximum clamping voltage (VC) at 51.6A peak pulse current (IPP), and IEC-61000-4-2 ESD immunity of 30kV (air/contact). It is used in industrial power supplies, automotive infotainment interfaces, and PoE-powered equipment.
For engineers reviewing the 3.0SMCJ36CA-13 datasheet, 3.0SMCJ36CA-13 pinout, 3.0SMCJ36CA-13 application, or 3.0SMCJ36CA-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, peak pulse current handling under IEC 61000-4-5 surge waveforms, thermal derating above +25°C ambient, and SMC package solderability per MIL-STD-202.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<5µA at VRWM), critical for low-power sensor interfaces.
The device complies with IEC-61000-4-2 Level 4 (30kV air/30kV contact) and supports high-reliability applications via JEDEC-qualified construction. Thermal performance is defined by a -55°C to +150°C operating junction range and 100% lead-free, halogen-free "Green" packaging per IATF 16949 manufacturing standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10/1000µs surges up to 51.6A without failure |
| Reverse Standoff Voltage (VRWM) | 36V - maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage (VBR) | 40.0–44.2V @ 1.0mA - precise triggering threshold for overvoltage events |
| Clamping Voltage (VC) | 58.1V @ 51.6A - limits transient voltage seen by downstream circuitry |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling discharge |
| Operating Temperature | -55°C to +150°C - suitable for under-hood automotive and industrial environments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating; terminals are matte tin-plated for reliable solderability per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Input terminal for negative transients | One side of symmetrical bi-directional junction; no polarity marking required |
| Cathode (K) | Input terminal for positive transients | Opposite side of symmetrical bi-directional junction; identical to Anode in function |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping architecture | Enables single-device protection of AC signals or ungrounded buses without polarity concerns |
| Glass-passivated die construction | Ensures stable VBR over temperature and lifetime, with <5µA IR at VRWM |
| 3000W peak pulse rating | Handles IEC 61000-4-5 combination wave surges (e.g., 2Ω/12Ω source impedance) in telecom and industrial ports |
| Lead-free, halogen-free "Green" compliance | Meets RoHS 3 (2015/863/EU) with <900ppm Br, <900ppm Cl, <1000ppm Sb - supports eco-design requirements |
Applications
| Industrial PLC I/O Protection | Automotive Infotainment USB Ports |
|---|---|
Use Scenario: 24V DC input lines on programmable logic controller modules exposed to inductive switching transients from solenoids and relays. IC Role / Device Role / Timing Role: Bi-directional TVS placed upstream of DC-DC converter input to clamp fast-rising spikes before they reach regulation circuitry. Use Value: 58.1V clamping voltage ensures protected 24V rail stays below 60V absolute maximum rating of common buck controllers. |
Use Scenario: USB 2.0 data lines (D+/D−) in head unit designs subjected to ESD during connector insertion or user contact. IC Role / Device Role / Timing Role: Low-capacitance bi-directional TVS placed directly at USB connector to shunt ESD energy before it reaches USB transceiver PHY. Use Value: 30kV IEC-61000-4-2 contact discharge rating meets automotive OEM ESD test requirements without signal integrity degradation. |
| PoE-Powered Surveillance Cameras | Smart Meter Communication Interfaces |
Use Scenario: 48V DC power input on IEEE 802.3af/at powered devices subject to lightning-induced surges on outdoor Ethernet cabling. IC Role / Device Role / Timing Role: Primary surge protector on PoE PD front-end, coordinated with secondary MOV or GDT for multi-stage protection. Use Value: 3000W rating handles 10/1000µs surges up to 51.6A, providing robust first-line defense before downstream TVS arrays. |
Use Scenario: RS-485 communication lines in utility smart meters installed in electrically noisy substations or distribution panels. IC Role / Device Role / Timing Role: Bi-directional TVS on differential bus lines to suppress common-mode surges induced by nearby switching events or ground potential differences. Use Value: Symmetrical clamping ensures equal protection on A/B lines, preserving differential signaling integrity during 1kV/1.2×50µs surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA-13 (Diodes Inc.) | Same VRWM/VC but lower 600W PPK rating and SMB package (smaller 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 |
| SMCJ36CA (ON Semiconductor) | Identical electrical specs and SMC package; minor differences in marking and traceability documentation | Drop-in replacement with same thermal and mechanical footprint; qualified to AEC-Q101 | Prefer for automotive programs requiring AEC-Q101 qualification and PPAP support |
Compared with SMBJ36CA-13, the 3.0SMCJ36CA-13 delivers 5× higher surge energy handling in the same SMC footprint; versus SMCCJ36CA, it offers identical protection performance with Diodes' JEDEC-qualified process and RoHS 3-compliant materials.

FAQ
What is the difference between 3.0SMCJ36CA-13 and 3.0SMCJ36A-13?
The "C" suffix denotes bi-directional configuration, meaning the device clamps transients of either polarity symmetrically. The non-C version (3.0SMCJ36A-13) is uni-directional and features a cathode band marking; it conducts only during positive overvoltage events relative to its marked cathode. This distinction is critical for AC or floating signal line protection.
Can 3.0SMCJ36CA-13 be used in place of a 33V-rated TVS?
No - substituting a 36V VRWM device for a 33V design risks insufficient clamping margin. At 33V system rails, a 33V TVS (e.g., 3.0SMCJ33CA-13) provides tighter clamping (VC = 53.3V) versus 58.1V for the 36V part. Exceeding the protected IC's absolute maximum rating remains possible if the higher VC is not validated against downstream component tolerances.
Is thermal derating required for continuous operation above 25°C ambient?
Yes - the device's peak pulse power must be linearly derated above +25°C per Figure 1 in DS30818. At +85°C ambient, only ~70% of rated 3000W is sustainable; at +125°C, it drops to ~40%. PCB copper area, airflow, and adjacent heat sources must be modeled to ensure safe junction temperature remains ≤+150°C during surge events.
Does 3.0SMCJ36CA-13 meet AEC-Q200 stress testing requirements?
No - while manufactured in IATF 16949-certified facilities and qualified to JEDEC reliability standards, this standard-grade part lacks formal AEC-Q200 qualification. For automotive applications requiring AEC-Q200, Diodes offers the Q-suffix variant (e.g., 3.0SMCJ36CAQ-13), which undergoes additional temperature cycling, humidity bias, and mechanical shock validation.
