Product details
Overview
3.0SMCJ64A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 64V reverse standoff voltage, 71.1–78.6V breakdown range at 1mA, and 103V max clamping voltage at 29.1A peak pulse current. It provides IEC-61000-4-2 ESD protection (30kV air/30kV contact), HBM 8kV, and is used for DC power rail surge suppression in industrial power supplies and automotive ECUs.
For engineers reviewing the 3.0SMCJ64A-13 datasheet, 3.0SMCJ64A-13 pinout, 3.0SMCJ64A-13 application, or 3.0SMCJ64A-13 equivalent, this part delivers verified 3000W peak pulse power handling in SMC package, precise 64V VRWM tolerance, low 5µA leakage at rated voltage, and AEC-Q qualified variants for automotive-grade reliability validation.
Technical Context
This TVS diode operates as a clamping-type overvoltage protector, triggered when transient voltage exceeds its 71.1V minimum breakdown threshold. Its glass-passivated junction ensures stable VBR over temperature and long-term reliability under repetitive surge stress.
Designed for unidirectional operation, it features a cathode band marking and conducts only during negative transients on the anode side. Thermal derating follows JEDEC J-STD-020 Level 1 moisture sensitivity and supports continuous operation from –55°C to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10×1000µs surges up to 29.1A without failure |
| Reverse Standoff Voltage (VRWM) | 64V - maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 71.1–78.6V @ 1mA - precise clamping onset window for predictable protection margin |
| Max Clamping Voltage (VC) | 103V @ 29.1A - limits downstream IC voltage stress during worst-case surge |
| Reverse Leakage (IR) | 5µA @ 64V - negligible standby power loss and minimal impact on high-impedance circuits |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - meets industrial immunity requirements |
| Operating Temperature | –55°C to +150°C - suitable for under-hood automotive and industrial ambient conditions |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating; weight ≈ 0.21g; matte tin-plated leads solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Transient current return path to ground reference | Marked with band; must be tied to system ground or low-impedance return plane |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Ensures stable VBR across temperature and lifetime; eliminates passivation-related drift in harsh environments |
| 3000W peak pulse power rating | Supports high-energy lightning-induced surges (IEC 61000-4-5 Level 4) without degradation |

| RoHS-compliant, halogen-free "Green" design | Meets EU Directive 2015/863/EU with <900ppm Br, <900ppm Cl, <1000ppm Sb - compliant for automotive and industrial green procurement |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 48V DC input stage of programmable logic controller (PLC) power module exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp transients before they reach DC-DC converter ICs. Use Value: Limits voltage to ≤103V during 3000W surges, preventing damage to 100V-input buck controllers and maintaining system uptime. |
Use Scenario: 12V battery-fed microcontroller supply rail in BCM subjected to ISO 7637-2 pulse 1, 2a, and 5a transients. IC Role / Device Role / Timing Role: Primary front-end surge clamp on VBAT line, coordinated with upstream fuse and downstream LC filter. Use Value: Survives 100V/50ms load dump events while holding rail below 103V, avoiding brownout resets and EEPROM corruption. |
| Telecom PoE+ Midspan Surge Protection | Renewable Energy Inverter DC Link |
Use Scenario: 57V PoE+ (IEEE 802.3at) midspan injector output port subject to Ethernet cable ESD and induced surges. IC Role / Device Role / Timing Role: Bidirectional-capable variant (3.0SMCJ64CA-13) used across differential pairs; unidirectional version applied to common-mode rail-to-ground paths. Use Value: Clamps 30kV ESD strikes within nanoseconds, preserving PHY IC integrity without signal distortion on data lines. |
Use Scenario: 600V DC link in solar string inverter exposed to lightning-induced common-mode surges on PV array inputs. IC Role / Device Role / Timing Role: Paired unidirectional TVS units protect gate driver supply rails referenced to high-side switches. Use Value: Maintains gate drive stability by limiting auxiliary supply transients to <103V, preventing false turn-on of 650V SiC MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A (Diodes Inc.) | Same 64V VRWM but lower 600W PPK rating; SMB package (smaller footprint, lower thermal mass) | Limited to sub-10A surge currents; unsuitable for IEC 61000-4-5 Level 4 compliance | Select when space-constrained and surge energy is ≤600W; verify thermal dissipation in PCB layout |
| 1.5SMC64A (ON Semiconductor) | Identical 64V VRWM and 3000W rating, but higher 108V clamping voltage (vs. 103V); slightly wider VBR tolerance (64.0–77.4V) | Higher clamping increases stress on downstream 75V-rated components; less margin for tight-voltage-rail designs | Acceptable where 108V clamping is within system OV threshold; confirm compatibility with existing BOM qualification |
Compared with SMBJ64A and 1.5SMC64A, the 3.0SMCJ64A-13 offers superior clamping performance (103V vs. ≥108V) and identical 3000W surge capacity in a robust SMC package-making it optimal for high-reliability industrial and automotive front-end protection where voltage margin and thermal endurance are critical.

FAQ
What is the polarity configuration of 3.0SMCJ64A-13?
The 3.0SMCJ64A-13 is a unidirectional TVS diode with cathode-band marking. It conducts only when the anode is driven negative relative to cathode-ideal for DC rail protection where polarity is fixed. It does not conduct during positive transients unless paired with a second device or used in bi-directional configuration (3.0SMCJ64CA-13).
Can this TVS diode replace a Zener diode in overvoltage protection circuits?
No-it is not a voltage regulator. While both use PN junctions, the 3.0SMCJ64A-13 is optimized for high-energy transient clamping, not steady-state regulation. Its VBR has wider tolerance (±10.6%), and it lacks the low dynamic impedance needed for precision regulation. Use only for surge suppression, not DC voltage control.
How does the 3000W rating translate to real-world surge duration and repetition?
The 3000W rating applies to non-repetitive 10×1000µs waveform per Fig. 2 in DS30818. Per Fig. 1, derating begins above +25°C ambient; at +85°C, peak power drops to ~2100W. Duty cycle must remain ≤4 pulses/minute to avoid thermal accumulation and ensure long-term reliability.
Is 3.0SMCJ64A-13 qualified for automotive applications?
The base 3.0SMCJ64A-13 is not AEC-Q200 qualified. However, Diodes offers automotive-grade equivalents (e.g., 3.0SMCJ64AQ-13) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. For automotive use, specify the Q-suffix variant and consult Diodes' automotive product portal.
