Product details
Overview
3.0SMCJ75A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 75V reverse standoff voltage, 83.3V minimum breakdown voltage at 1.0mA test current, and 121V maximum clamping voltage at 24.8A peak pulse current. It provides IEC-61000-4-2 ESD protection (30kV air/30kV contact), operates from –55°C to +150°C, and is used in DC power rail surge protection for industrial motor drives and telecom power supplies.
For engineers reviewing the 3.0SMCJ75A-13 datasheet, 3.0SMCJ75A-13 pinout, 3.0SMCJ75A-13 application, or 3.0SMCJ75A-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 diode uses glass-passivated silicon junction construction to achieve low leakage (<5μA at 75V), fast response time (<1.0ps), and stable clamping performance across temperature. Its unidirectional configuration enables integration into DC-biased lines where reverse polarity protection is not required.
The device complies with JEDEC high-reliability standards and supports automotive-grade qualification via Q-suffix variants. It is rated for 300A non-repetitive forward surge current (8.3ms half-sine) when mounted on 8.00mm² copper land, with pulse derating following Fig. 1 in DS30818 Rev. 18-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10/1000μs transients without failure under defined mounting conditions |
| Reverse Standoff Voltage (VRWM) | 75V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 83.3–92.1V @ 1.0mA - ensures reliable conduction onset during overvoltage events |
| Clamping Voltage (VC) | 121V @ 24.8A - limits downstream voltage stress to safe levels during surge |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling discharge |
| Operating Temperature | –55°C to +150°C - supports deployment in under-hood automotive and industrial environments |
| Package | SMC (DO-214AB) - surface-mount footprint compatible with automated assembly and thermal relief design |

Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
|
Use Scenario: Protection of 48V DC bus against load dump and inductive kickback in servo drive controllers. IC Role / Device Role / Timing Role: Unidirectional TVS placed between rail and ground to clamp transients within 1.0ps response window. Use Value: Clamps to 121V max at 24.8A, ensuring protected gate drivers and MCU I/O remain below absolute maximum ratings. |

| Automotive Body Control Modules | Renewable Energy Inverters |
|
Use Scenario: Protecting LIN bus power rails and sensor supply lines in BCMs exposed to ISO 7637-2 pulse 5a/b. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing repetitive 10/1000μs pulses up to 3000W without parametric shift. Use Value: Operates reliably from –55°C to +150°C, meeting under-hood thermal requirements without derating penalty. |
Use Scenario: DC-link surge protection in solar microinverters subjected to grid-switching transients. IC Role / Device Role / Timing Role: High-power TVS placed across PV string inputs to limit voltage overshoot during rapid irradiance changes. Use Value: 121V clamping voltage provides ≥15% margin over 100V-rated electrolytic capacitors in DC-link stage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A (Diodes Inc.) | Lower 600W peak power, SMB package (smaller thermal mass), same 75V VRWM and 121V VC | Suitable only for lower-energy transients; limited to ≤10A IPP under 10/1000μs | Select when board space is constrained and surge energy remains below 600W |
| 1.5SMC75A (ON Semiconductor) | Same SMC package and 75V VRWM, but 1500W peak power and 125V VC at 12A IPP | Insufficient for 3000W IEC 61000-4-5 Level 4 compliance; requires parallel devices for equivalent energy handling | Choose only if legacy BOM alignment outweighs need for single-device 3000W capability |
Compared with SMBJ75A and 1.5SMC75A, the 3.0SMCJ75A-13 delivers double the pulse power of the SMBJ and double the clamping current of the 1.5SMC, enabling single-device compliance with IEC 61000-4-5 surge immunity up to 4kV in 2Ω/12Ω coupling networks.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ75A-13 under standard test conditions?
The maximum clamping voltage is 121V at 24.8A peak pulse current, measured using the 10 x 1000μs waveform per Figure 2 in DS30818 Rev. 18-2. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 3.0SMCJ75A-13 RoHS and halogen-free compliant?
Yes - it meets EU Directive 2015/863/EU (RoHS 3) with lead-free finish and contains <900ppm bromine, <900ppm chlorine (total Br+Cl <1500ppm), and <1000ppm antimony compounds, satisfying Diodes' "Green" device definition per their quality documentation.
Does the 3.0SMCJ75A-13 have automotive qualification?
The base part is not AEC-Q200 qualified, but Diodes offers Q-suffix variants (e.g., 3.0SMCJ75AQ-13) manufactured in IATF 16949-certified facilities and qualified to AEC-Q200 for automotive applications requiring change control and PPAP documentation.
How does thermal derating affect the 3.0SMCJ75A-13's peak pulse power above +25°C?
Per Figure 1 in DS30818, peak pulse power linearly derates to 50% at +125°C ambient. At +100°C, it retains ~75% of rated 3000W capability. Derating applies to both power and peak current, and assumes mounting on 8.00mm² copper land per JEDEC test conditions.
