Product details
Overview
3.0SMCJ160AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 160V reverse standoff voltage (VRWM), 259V maximum clamping voltage (VC) at 11.6A peak pulse current (IPP), and IEC-61000-4-2 ESD immunity up to 30kV (air/contact). It is used in automotive power supply inputs requiring AEC-Q101 qualification.
For engineers reviewing the 3.0SMCJ160AQ-13 datasheet, 3.0SMCJ160AQ-13 pinout, 3.0SMCJ160AQ-13 application, or 3.0SMCJ160AQ-13 equivalent, key selection criteria include clamping performance under 10/1000μs surge, thermal derating above +25°C, unidirectional polarity marking, and SMC package compatibility with IPC-7351B land patterns.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during transients, leveraging avalanche breakdown to shunt surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<5µA at VRWM).
The device is rated for -55°C to +150°C operating junction temperature and exhibits defined pulse derating per Fig. 1 of DS30818 Rev. 18–2: peak power drops to ~70% at +100°C ambient. It supports single-pulse 8.3ms half-sine surges up to 300A when mounted on 8.00mm² copper land areas.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10×1000μs surge without failure under specified mounting conditions |
| Reverse Standoff Voltage (VRWM) | 160V - maximum continuous DC or RMS voltage before significant leakage begins |
| Clamping Voltage (VC) | 259V @ IPP = 11.6A - limits transient voltage seen by protected ICs to ≤259V |
| Breakdown Voltage (VBR) | 178–196.7V @ IT = 1mA - defines onset of avalanche conduction with tight tolerance |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling electrostatic discharge |
| Operating Temperature | -55°C to +150°C - qualified for under-hood automotive environments and industrial power systems |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating; weight ≈0.21g; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode Band (Marked End) | Anode Reference / Ground-Side Terminal | Identifies cathode; connects to protected line; anode ties to system ground or lower-potential rail |
| Unmarked End | Cathode / High-Side Terminal | Connects to input/power rail being protected; conducts avalanche current toward ground during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 3000W Peak Pulse Power | Enables robust protection against ISO 7637-2 Pulse 1/2a/5a transients in 12V/24V automotive systems |
| Glass-Passivated Die | Ensures long-term reliability and stable VBR drift <±5% over 1000hr HTOL testing at 150°C |
| AEC-Q101 Qualified | Validated for automotive use including stress tests: HTRB, HTGB, TCT, UHAST, and ESD per JESD22 |
| Lead-Free & Halogen-Free | Complies with RoHS 3 (2015/863/EU) and Diodes' "Green" definition: Br+Cl <1500ppm, Sb <1000ppm |
Applications
| Automotive Power Input Protection | Industrial DC Power Rail Clamping |
|---|---|
Use Scenario: 12V/24V battery-fed ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor. Use Value: Clamps ISO 7637-2 Pulse 5a (75V/100ms) to ≤259V, preventing damage to upstream PMICs and microcontrollers. |
Use Scenario: 48V telecom rectifier output subjected to lightning-induced surges on outdoor plant wiring. IC Role / Device Role / Timing Role: Primary surge shunt device located at board edge before DC-DC converter input. Use Value: Absorbs 3000W 10×1000μs transients without degradation, maintaining system uptime in harsh environments. |
| Automotive CAN Transceiver Protection | Smart Sensor Signal Line Guarding |
Use Scenario: CAN_H/CAN_L lines in vehicle body control modules interfacing with external harnesses. IC Role / Device Role / Timing Role: Bi-directional TVS pair (e.g., 3.0SMCJ24AQ) used-this part is unidirectional and not applicable here; however, its 160V rating suits 12V supply-side CAN transceiver VCC protection. Use Value: Prevents latch-up or burnout of CAN PHY during battery disconnect transients by clamping VCC rail to safe levels. |
Use Scenario: Analog sensor outputs (e.g., pressure, temperature) routed through long cables in factory automation. IC Role / Device Role / Timing Role: Unidirectional TVS on sensor VDD line, grounded at local PCB return plane. Use Value: Limits induced surges to <259V, preserving ADC reference integrity and avoiding offset drift in precision front-ends. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | 2000W PPK, same VRWM (160V), higher VC (274V @ 10.9A), SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a in automotive due to lower power rating | Select when board space is constrained and surge threat level is ≤2000W (e.g., consumer IoT, non-critical sensors) |
| SMCJ160A | Same 3000W rating and SMC package, but standard-grade (non-AEC-Q101); no automotive change control or PPAP support | Not approved for production automotive programs requiring AEC-Q101 documentation and IATF 16949 traceability | Use only in industrial or commercial designs where automotive qualification is not required |
Compared with SMBJ160A and SMCJ160A, the 3.0SMCJ160AQ-13 delivers identical clamping and package benefits while adding AEC-Q101 qualification, full PPAP capability, and guaranteed sourcing for automotive OEMs-making it the sole choice for Tier 1 production programs.

FAQ
What does the 'Q' suffix signify in 3.0SMCJ160AQ-13?
The 'Q' suffix indicates AEC-Q101 qualification: the device has passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per JESD22, and is manufactured in IATF 16949-certified facilities with full PPAP documentation support for automotive production programs.
Can 3.0SMCJ160AQ-13 be used in bi-directional protection circuits?
No-it is a unidirectional TVS diode with a cathode band marking; it conducts only during positive transients on the cathode side. For bi-directional protection (e.g., AC lines or differential data buses), a dedicated bi-directional variant such as 3.0SMCJ160CA-13 must be selected.
What is the recommended PCB layout for optimal thermal performance?
Mount the SMC package on ≥8.00 mm² copper land area per terminal, using thermal vias to inner-layer ground planes. Maintain ≥1.5mm clearance from adjacent components and avoid solder mask over thermal pads to maximize heat dissipation during surge events.
How does clamping voltage vary with pulse duration and amplitude?
Clamping voltage is specified at 10×1000μs waveform (259V @ 11.6A). Shorter pulses (e.g., 8/20μs) yield lower VC; longer pulses increase junction temperature and may raise VC by up to 8% at 100°C ambient, per Fig. 1 derating curve in DS30818.
