Product details
Overview
3.0SMCJ17A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 17V standoff voltage, 27.6V clamping voltage at 10.9A peak pulse current, and IEC-61000-4-2 ESD rating of 30kV (air/contact). It protects DC power rails and signal lines in industrial motor drives, telecom power supplies, and automotive body control modules against lightning-induced surges and EFT.
For engineers reviewing the 3.0SMCJ17A-13 datasheet, 3.0SMCJ17A-13 pinout, 3.0SMCJ17A-13 application, or 3.0SMCJ17A-13 equivalent, this device is selected for high-energy surge immunity in 24V/48V systems where clamping voltage margin, low leakage (<5µA @ 17V), and SMC package thermal robustness are critical design constraints.
Technical Context
This TVS operates as a silicon avalanche diode, triggered when reverse voltage exceeds its 17V VRWM threshold, entering low-impedance conduction to clamp transients within 1 ns. Its glass-passivated die ensures stable breakdown characteristics across -55°C to +150°C operating range.
The device sustains 3000W peak pulse power per 10×1000µs waveform and handles 300A non-repetitive forward surge current under 8.3ms half-sine conditions. Its unidirectional polarity requires cathode-band orientation toward positive rail for proper protection configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - clamps 10×1000µs transients without failure in industrial surge environments |
| Reverse Standoff Voltage (VRWM) | 17V - maximum continuous DC voltage before clamping initiates; matches 24V system nominal rails |
| Clamping Voltage (VC) | 27.6V @ 10.9A - limits downstream IC voltage stress during 1kV EFT or 6kV lightning surge |
| Breakdown Voltage (VBR) | 18.9–20.9V @ 1mA - tight 10.5% tolerance ensures predictable turn-on across temperature |
| Leakage Current (IR) | <5µA @ 17V - negligible standby power loss in always-on battery-backed circuits |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects front-panel interfaces against human handling events |
| Operating Temperature | -55°C to +150°C - qualified for under-hood automotive and industrial enclosure deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A (Diodes Inc.) | Lower 600W peak power, SMB package, same 17V VRWM and 27.6V VC | Suitable only for sub-IEC 61000-4-5 Level 2 surges; limited thermal mass for repeated events | Select when board space is constrained and surge energy is ≤600W |
| 1.5SMCJ17A (ON Semiconductor) | Same 3000W rating and 17V/27.6V specs, but JEDEC MO-136 (SMC) footprint differs in leadform tolerances | Requires revalidation of solder joint reliability due to minor package dimensional variance | Select when sourcing from ON Semi's qualified automotive supply chain is required |
Compared with SMBJ17A and 1.5SMCJ17A, the 3.0SMCJ17A-13 delivers identical clamping performance with higher thermal mass for multi-pulse resilience, while maintaining full SMC footprint compatibility for drop-in replacement in existing layouts.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ17A-13 under standard test conditions?
The maximum clamping voltage (VC) is 27.6V at 10.9A 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 (-55°C to +150°C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 3.0SMCJ17A-13 suitable for bidirectional signal line protection?
No - it is a unidirectional TVS diode with a cathode band marking, designed exclusively for DC power rail protection. For bidirectional signal lines such as RS-485 or USB data pairs, the bi-directional variant 3.0SMCJ17CA-13 must be used, which has symmetrical clamping in both polarities and no polarity indicator.
How does the SMC package affect thermal performance compared to SMA or SMB?
The SMC package provides 2.5× greater thermal mass than SMB and 4× greater than SMA, enabling sustained 3000W pulse dissipation without thermal runaway. Its 8mm² copper land requirement (per datasheet Fig. 1) delivers 30% lower junction-to-board thermal resistance, critical for repeated surge duty cycles in enclosed enclosures.
Does this part meet AEC-Q200 requirements for automotive use?
The base 3.0SMCJ17A-13 is not AEC-Q200 qualified; however, Diodes offers the automotive-grade Q-suffix variant 3.0SMCJ17AQ-13, which undergoes additional stress testing including temperature cycling, humidity bias HAST, and mechanical shock per AEC-Q200 Rev D, and is manufactured in IATF 16949-certified facilities.
