Product details
Overview
3.0SMCJ54A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 54V reverse standoff voltage, 60.0–66.3V breakdown range at 1mA, and 87.1V max clamping voltage at 34.4A peak pulse current. It provides IEC-61000-4-2 ESD protection (30kV air/30kV contact), HBM 8kV, and is used in DC power rail protection for industrial PLCs, telecom power supplies, and automotive body control modules.
For engineers reviewing the 3.0SMCJ54A-13 datasheet, 3.0SMCJ54A-13 pinout, 3.0SMCJ54A-13 application, or 3.0SMCJ54A-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, peak pulse current handling under 10/1000μs surge, 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 VBR (60.0–66.3V), it avalanches into low-impedance conduction to shunt surge energy away from downstream circuitry. Its glass-passivated die ensures stable breakdown and low leakage (<5µA @ 54V).
It is rated for non-repetitive 10×1000μs waveform surges up to 34.4A, with peak power dissipation derated linearly above +25°C (e.g., ~75% at +85°C). The unidirectional configuration requires correct cathode-band orientation on PCB layout to protect positive-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000μs transients without failure |
| Reverse Standoff Voltage (VRWM) | 54V - maximum continuous DC voltage before leakage exceeds 5µA |
| Breakdown Voltage (VBR) | 60.0–66.3V @ 1mA - guaranteed avalanche initiation window for predictable clamping onset |
| Max Clamping Voltage (VC) | 87.1V @ 34.4A - upper limit of voltage seen by protected load during worst-case surge |
| Peak Pulse Current (IPP) | 34.4A - maximum surge current the device can safely clamp per IEC 61000-4-5 |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-hand electrostatic discharge events |
| Operating Temperature | −55°C to +150°C - supports under-hood automotive and industrial environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ54A-13 (Diodes Inc.) | Lower 600W peak power; same 54V VRWM and 87.1V VC, but IPP = 6.9A | Suitable only for low-energy ESD and low-dI/dt transients; insufficient for load dump or lightning | Select when board space is constrained and surge threat level is limited to IEC-61000-4-2 only |
| 1.5SMCJ54A (ON Semiconductor) | Identical 3000W rating, 54V VRWM, and 87.1V VC; same SMC package; minor differences in leakage (<1µA vs. <5µA) | Drop-in compatible for most designs; validated for AEC-Q200 Grade 1 (−40°C to +125°C) | Choose for automotive-qualified supply chain continuity where Diodes' Q-grade version is unavailable |
Compared with SMBJ54A-13, 3.0SMCJ54A-13 delivers >4× higher surge current capacity; versus 1.5SMCJ54A, it offers identical clamping performance but differs in JEDEC qualification scope and traceability documentation.

FAQ
What is the maximum clamping voltage of 3.0SMCJ54A-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 87.1V at 34.4A peak pulse current, measured under the standardized 10×1000μs waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range and represents the highest voltage the protected circuit will experience during a worst-case surge event.
Is 3.0SMCJ54A-13 suitable for bidirectional signal line protection?
No - 3.0SMCJ54A-13 is unidirectional, indicated by its cathode band marking. It protects only positive-going transients on a referenced rail. For bidirectional protection (e.g., RS-485, USB data lines), use the bi-directional variant 3.0SMCJ54CA-13, which has symmetric clamping for both polarities and no polarity marking.
How does thermal derating affect its surge capability above +25°C ambient?
Per Figure 1 in DS30818 Rev. 18, peak pulse power and current are linearly derated: at +85°C ambient, capability drops to ~75% of rated 3000W/34.4A; at +125°C, it falls to ~45%. Layout must include ≥8mm² copper pad area per terminal to maintain thermal performance per test conditions.
Does this TVS require series impedance for optimal protection?
Yes - a series current-limiting resistor or ferrite bead is recommended upstream to reduce di/dt and extend TVS lifetime during repetitive surges. Without it, high di/dt can cause localized heating at the bond wire, degrading clamping consistency over time, especially in applications with frequent transients like motor drives.
