Product details
Overview
3.0SMCJ36A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode designed for primary 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, and IEC-61000-4-2 ESD immunity (30kV air/30kV contact). It is used in industrial power supplies to safeguard downstream DC-DC converters against lightning-induced surges.
For engineers reviewing the 3.0SMCJ36A-13 datasheet, 3.0SMCJ36A-13 pinout, 3.0SMCJ36A-13 application, or 3.0SMCJ36A-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current capability 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 crowbar device: when transient voltage exceeds its breakdown threshold (40.0–44.2V), it avalanches into low-impedance conduction, diverting surge current away from sensitive circuitry while holding voltage across the protected node ≤58.1V. Its glass-passivated die ensures stable leakage and repeatable clamping performance.
It is rated for 3000W peak pulse power (10×1000μs waveform), 300A non-repetitive forward surge current (8.3ms half-sine), and operates across –55°C to +150°C junction temperature. The unidirectional configuration includes a cathode band for polarity identification and requires correct orientation in series with the protected line.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10/1000μs transients without failure; defines maximum energy absorption capacity |
| Reverse Standoff Voltage (VRWM) | 36V - maximum continuous DC or RMS voltage before significant leakage; sets operating rail compatibility |
| Breakdown Voltage (VBR) | 40.0–44.2V @ 1.0mA - guaranteed avalanche initiation range; determines earliest clamping onset |
| Clamping Voltage (VC) | 58.1V @ 51.6A - maximum voltage seen by protected circuit during full-rated surge; critical for IC survivability |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - qualifies for direct interface protection in harsh industrial environments |
| Junction Temperature Range | –55°C to +150°C - enables deployment in under-hood automotive modules and high-temperature industrial enclosures |
Pinout & Package
Package: SMC (DO-214AB), surface-mount molded plastic body with matte tin-plated leads; UL 94V-0 flammability rating; 0.21g typical weight; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-to-cathode conduction path | Current flows from anode to cathode during forward surge; cathode must connect toward protected load side in unidirectional configuration |
| Anode (unmarked end) | Transient return path | Connected to ground or low-impedance return plane; completes surge current loop during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| 3000W peak pulse power dissipation | Enables robust protection against IEC 61000-4-5 Level 4 (4kV line-to-earth) surges without thermal runaway |
| Glass-passivated die construction | Ensures stable VBR tolerance and low leakage (<5µA @ VRWM) over 10+ year field life |
| Lead-free, RoHS-compliant, halogen-free "Green" finish | Meets IPC-J-STD-020 moisture sensitivity level 1 and automotive PPAP requirements without post-process reflow concerns |
| Excellent clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream 48V-rated components such as CAN transceivers or microcontroller I/O |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
|
Use Scenario: Protection of 48V DC input stage in variable-frequency drives exposed to inductive kickback and utility grid transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of bulk capacitor and PFC controller. Use Value: Clamps 1kV/0.5Ω surge to ≤58.1V, preventing MOSFET gate oxide rupture and bootstrap capacitor overvoltage failure. |

| Automotive Body Control Modules | Renewable Energy Inverters |
|
Use Scenario: Input rail protection in 12V/24V BCMs subjected to ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 5a (load dump). IC Role / Device Role / Timing Role: First-line defense on battery feed, positioned before fuse and main regulator.

Use Scenario: DC-link overvoltage suppression in solar string inverters where PV array transients couple into MPPT input. IC Role / Device Role / Timing Role: Bidirectional-capable variant used (3.0SMCJ36CA-13); here, unidirectional version applied on grounded-negative PV input. Use Value: Absorbs 6kV/0.5Ω combination wave per IEC 61000-4-5, limiting voltage overshoot to <60V on 600V-rated SiC gate drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A (Diodes Inc.) | Lower peak power (600W), same VRWM/VBR/VC, SMB package (smaller footprint, lower thermal mass) | Not suitable for IEC 61000-4-5 Level 4; limited to sub-1kV surges in space-constrained consumer electronics | Select when board area is constrained and surge threat level is ≤IEC Level 2; verify thermal derating at >+85°C ambient |
| 1.5SMCJ36A (ON Semiconductor) | Same electrical specs but 1500W peak power (50% lower), identical SMC package, JEDEC JESD22-A114 HBM 8kV rating | Insufficient for 3000W surge events; requires parallel placement or higher-tier TVS for full industrial compliance | Use only in cost-sensitive designs with verified lower surge exposure; confirm clamping margin remains >20% above protected IC VABS MAX |
Compared with SMBJ36A and 1.5SMCJ36A, the 3.0SMCJ36A-13 delivers double the surge energy handling of the SMBJ and twice the peak power of the 1.5SMCJ, enabling single-device compliance with IEC 61000-4-5 Level 4 in 48V industrial systems without thermal compromise.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ36A-13 under full-rated surge conditions?
The maximum clamping voltage (VC) is 58.1V at 51.6A peak pulse current, measured using the standardized 10×1000μs waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range and defines the absolute upper voltage limit imposed on protected circuitry during worst-case transient events.
Can the 3.0SMCJ36A-13 be used in bidirectional configurations?
No-the "A" suffix denotes unidirectional operation with a cathode band; bidirectional variants use the "CA" suffix (e.g., 3.0SMCJ36CA-13). Using the unidirectional part in reverse-biased AC applications risks catastrophic failure due to lack of reverse avalanche capability and excessive leakage beyond VRWM.
How does the SMC package affect thermal performance compared to SMA or SMB?
The SMC package offers ~2.5× the thermal mass and ~30% lower junction-to-ambient resistance versus SMA, enabling sustained 3000W pulse dissipation without localized overheating. Its larger pad layout (8.00mm² recommended land area) supports efficient heat spreading into PCB copper, critical for repeated surge duty cycles.
Is the 3.0SMCJ36A-13 qualified for automotive applications?
The standard 3.0SMCJ36A-13 is not AEC-Q200 qualified; however, Diodes offers automotive-grade equivalents with "Q" suffix (e.g., 3.0SMCJ36AQ-13) that undergo additional testing for temperature cycling, mechanical shock, and humidity resistance, and are manufactured in IATF 16949-certified facilities.
