Product details
Overview
3.0SMCJ110AQ-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 power rails. It features a 110V reverse standoff voltage (VRWM), 177V maximum clamping voltage (VC) at 16.9A peak pulse current (IPP), and IEC-61000-4-2 ESD rating of 30kV (air/contact). It protects 110V DC bus lines against lightning-induced surges and load dump transients.
For engineers reviewing the 3.0SMCJ110AQ-13 datasheet, 3.0SMCJ110AQ-13 pinout, 3.0SMCJ110AQ-13 application, or 3.0SMCJ110AQ-13 equivalent, key selection criteria include clamping voltage margin relative to system operating voltage, peak pulse power handling under 10/1000μs waveform, thermal derating above +25°C ambient, and AEC-Q101 qualification status for automotive use.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (122–134.8V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated die ensures stable breakdown characteristics and long-term reliability under repetitive stress.
The device is rated for 3000W peak pulse power per 10×1000μs waveform, with thermal derating beginning at +25°C (per Fig. 1) and full operational range from –55°C to +150°C junction temperature. It supports both uni-directional (cathode-banded) and bi-directional variants, though this part is unidirectional per marking code HHE and cathode band indication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10/1000μs transients without failure; critical for ISO 7637-2 Load Dump immunity |
| Reverse Standoff Voltage (VRWM) | 110V - maximum continuous DC voltage before leakage exceeds 5μA; sets upper limit for protected rail |
| Clamping Voltage (VC) | 177V @ 16.9A - actual voltage seen by protected IC during worst-case surge; defines overvoltage margin |
| Breakdown Voltage (VBR) | 122–134.8V @ 1mA - guaranteed avalanche initiation window; ensures predictable turn-on behavior |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - qualifies for front-panel and connector-level ESD hardening |
| Operating Temperature | –55°C to +150°C - enables under-hood automotive deployment and industrial motor drive environments |

Applications
| Automotive Power Distribution | Industrial DC Bus Protection |
|---|---|
Use Scenario: Protecting 110V battery-fed ECUs against load dump transients in commercial vehicle electrical systems. IC Role / Device Role / Timing Role: Shunt-type transient voltage suppressor placed directly across main power input, clamping surges within 1ns response time. Use Value: Limits voltage excursion to ≤177V during 120V load dump events, preventing damage to 200V-rated MOSFETs and microcontrollers. |
Use Scenario: Safeguarding programmable logic controller (PLC) power inputs exposed to switching transients from solenoid drivers. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 110V DC supply rail upstream of DC-DC converters and I/O modules. Use Value: Absorbs up to 3000W of transient energy without degradation, maintaining system uptime in factory automation environments. |
| Telecom Power Feeds | Renewable Energy Inverters |
Use Scenario: Surge protection on 110V PoE++ midspan injectors powering remote radio units. IC Role / Device Role / Timing Role: Secondary-stage TVS after GDT-based primary protection, handling residual fast-rising transients. Use Value: Provides precise 177V clamping to protect IEEE 802.3bt-compliant PHY interfaces while meeting EN 61000-4-5 Level 4 requirements. |
Use Scenario: DC-link surge suppression in solar string inverters where PV array open-circuit voltage reaches 110V. IC Role / Device Role / Timing Role: Parallel-connected TVS on DC bus between MPPT stage and inverter bridge, triggered by lightning-induced surges. Use Value: Withstands repeated 10/1000μs surges up to 16.9A without parametric shift, ensuring 25-year field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-Q | 600W peak power, same VRWM and VC; smaller SMB package (3.56mm × 4.60mm) | Limited to lower-energy transients (e.g., ESD-only); unsuitable for load dump | Select when space-constrained and surge energy < 100mJ; verify IEC 61000-4-5 compliance separately |
| SMCJ110A | Same 3000W rating and SMC package, but not AEC-Q101 qualified; RoHS-compliant but not halogen-free | Acceptable for industrial non-automotive use; lacks PPAP support and automotive change control | Choose for cost-sensitive industrial designs where automotive qualification is unnecessary |
Compared with SMBJ110A-Q and SMCJ110A, the 3.0SMCJ110AQ-13 uniquely combines AEC-Q101 qualification, halogen-free construction, and full 3000W capability in the SMC footprint-making it the only option qualified for safety-critical automotive 110V rail protection with traceable lifecycle management.

FAQ
What is the meaning of the 'Q' suffix in 3.0SMCJ110AQ-13?
The 'Q' suffix indicates AEC-Q101 qualification, confirming that the device has passed stress tests for automotive applications-including temperature cycling, highly accelerated life testing (HALT), and ESD robustness. It also signifies PPAP capability and manufacturing in IATF 16949-certified facilities, enabling use in engine control, ADAS, and body electronics systems.
Can this TVS diode be used in bi-directional configurations?
No-3.0SMCJ110AQ-13 is unidirectional, as confirmed by its cathode band marking (HHE code) and electrical specification table listing only uni-directional parameters. For bi-directional protection at 110V standoff, Diodes offers the 3.0SMCJ110CA-13 variant, which lacks the cathode band and supports symmetrical clamping in AC or floating DC applications.
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 areas. Above +25°C, power capability drops per Figure 1: at +85°C ambient, it derates to ~2100W. Effective heat sinking via internal layers and thermal vias is essential to maintain clamping performance during repeated surges in enclosed enclosures.
Is the 177V clamping voltage measured at maximum rated current?
Yes-the 177V clamping voltage (VC) is guaranteed at the maximum peak pulse current (IPP) of 16.9A, tested using the standardized 10×1000μs waveform (Figure 2). This value represents worst-case voltage exposure to downstream components during full-rated surge events, not typical operating conditions.
