Product details
Overview
3.0SMCJ100AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial DC power lines. It features a 100V reverse standoff voltage (VRWM), 162V maximum clamping voltage (VC) at 18.5A peak pulse current (IPP), and IEC-61000-4-2 ESD immunity of 30kV (air/contact). It is AEC-Q101 qualified and used in 12V/24V/48V battery-supplied systems to protect CAN, LIN, and sensor interfaces.
For engineers reviewing the 3.0SMCJ100AQ-13 datasheet, 3.0SMCJ100AQ-13 pinout, 3.0SMCJ100AQ-13 application, or 3.0SMCJ100AQ-13 equivalent, key selection criteria include clamping voltage margin relative to system rail, peak pulse current handling under ISO 7637-2 Pulse 1/2b/5a, thermal derating above +25°C ambient, and SMC package solder joint reliability per J-STD-020 Level 1.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, triggered when transient voltage exceeds its 111V minimum breakdown voltage (VBR) at 1mA test current. Its unidirectional configuration provides forward conduction path during negative transients only when paired with external polarity control.
Clamping performance is defined per 10×1000μs waveform (IEC 61000-4-5), delivering 162V VC at 18.5A IPP while maintaining <5μA reverse leakage at 100V VRWM. Thermal operation spans –55°C to +150°C junction temperature, with pulse power derated linearly above +25°C per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000μs surges up to 18.5A without failure |
| Reverse Standoff Voltage | 100V - maximum continuous DC operating voltage before clamping initiates |
| Breakdown Voltage | 111–122.7V @ 1mA - ensures reliable turn-on margin above 100V rail with tolerance |
| Clamping Voltage | 162V @ 18.5A - limits downstream IC stress to safe level during ISO 7637-2 Pulse 5a |
| ESD Rating | 30kV air/contact per IEC-61000-4-2 - protects against human-hand electrostatic discharge events |
| Operating Temperature | –55°C to +150°C - supports under-hood automotive placement and industrial wide-temp environments |

Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
Use Scenario: Protecting 24V CAN FD bus lines from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between CAN_H/CAN_L and chassis ground to clamp common-mode surges. Use Value: Limits clamping voltage to 162V, staying below ISO 11898-2 receiver absolute max rating while surviving 3000W pulses. |
Use Scenario: Safeguarding 24V digital input channels on programmable logic controllers exposed to relay coil flyback. IC Role / Device Role / Timing Role: Primary surge suppression device mounted at connector entry point before optocoupler input stage. Use Value: Absorbs 18.5A peak current from inductive kickback without latch-up, preserving signal integrity and input threshold stability. |
| EV Battery Management System | Telecom Remote Radio Unit |
Use Scenario: Guarding 48V auxiliary power rails in battery management units against ISO 7637-2 Pulse 5a (load dump). IC Role / Device Role / Timing Role: High-power TVS connected directly across rail-to-ground to clamp fast-rising transients before DC-DC converter input. Use Value: Delivers 3000W peak dissipation with 162V clamping, enabling robust design margin over 48V nominal + 100% tolerance. |
Use Scenario: Protecting RS-485 communication ports on outdoor base station radios from lightning-induced surges. IC Role / Device Role / Timing Role: Secondary-level protection staged after gas discharge tube (GDT), providing low-clamp precision after coarse front-end filtering. Use Value: Achieves sub-100ns response time and 162V clamping to prevent damage to isolated transceivers rated for 200V abs max. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A | Lower peak power (400W), same 100V VRWM, SMC-compatible but smaller SMA package | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy ESD and EFT events | Select only for cost-sensitive non-automotive designs where 3000W surge immunity is not required |
| SMCJ100A | Same 3000W rating and SMC package, but lacks AEC-Q101 qualification and automotive traceability | Acceptable for industrial use but fails OEM automotive BOM approval due to missing PPAP and change control | Choose 3.0SMCJ100AQ-13 when automotive qualification, lot traceability, and IATF 16949 sourcing are mandatory |
Compared with SMAJ100A and SMCJ100A, the 3.0SMCJ100AQ-13 uniquely combines 3000W surge capacity, AEC-Q101 compliance, and full automotive supply chain support-making it the sole option for production-grade vehicle electronics requiring validated reliability and change control.

FAQ
What is the difference between the 'Q' suffix and standard SMCJ parts?
The 'Q' suffix denotes AEC-Q101 qualification: full automotive-grade testing (including temperature cycling, HTRB, and ESD), PPAP documentation, IATF 16949 manufacturing, and controlled change management. Standard SMCJ parts lack these certifications and are intended for industrial use only.
Can 3.0SMCJ100AQ-13 be used in bidirectional configurations?
No-it is unidirectional, indicated by the cathode band. For bidirectional protection, Diodes offers the 3.0SMCJ100CA-13 variant, which has symmetrical clamping in both polarities and no polarity marking. Using the Q-suffix unidirectional part in reverse-biased AC applications risks permanent failure.
How does thermal derating affect its 3000W rating in real-world PCB layouts?
The 3000W rating applies only at +25°C ambient with specified 8.00mm² copper land area. At +100°C ambient, derating reduces peak power to ~1800W (60% per Fig. 1). Layout must provide adequate copper pour and avoid thermal isolation to maintain clamping performance under repeated surges.
Is this device suitable for protecting USB or Ethernet data lines?
No-its 162V clamping voltage and 100V standoff are incompatible with low-voltage data interfaces. It is designed for power-line and high-voltage signal-line protection (e.g., CAN, LIN, 24V/48V sensors). For USB/Ethernet, use low-capacitance TVS arrays like D3V3Z5U or SP3052.
