Product details
Overview
3.0SMCJ16AQ-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 16V reverse standoff voltage (VRWM), 26.0V maximum clamping voltage (VC) at 115.4A peak pulse current (IPP), and IEC-61000-4-2 ESD immunity of 30kV (air/contact). It is used in automotive infotainment power inputs to absorb load-dump and ISO 7637-2 transients.
For engineers reviewing the 3.0SMCJ16AQ-13 datasheet, 3.0SMCJ16AQ-13 pinout, 3.0SMCJ16AQ-13 application, or 3.0SMCJ16AQ-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current capability under 10/1000μs waveform, thermal derating above +25°C ambient, and AEC-Q101 qualification status for automotive deployment.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, triggering when reverse voltage exceeds its breakdown threshold (17.8–19.7V at 1.0mA test current). Its unidirectional configuration provides low-leakage (<5μA @ VRWM) forward conduction path while clamping transients to ≤26.0V during 10×1000μs surges.
It is rated for -55°C to +150°C junction operation, complies with JEDEC high-reliability standards, and is manufactured in IATF 16949-certified facilities. The Q-suffix denotes AEC-Q101 qualification - confirmed by Diodes' automotive product portal - enabling use in engine control modules and ADAS power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000μs transients without failure |
| Reverse Standoff Voltage | 16.0V - maximum continuous DC operating voltage before leakage exceeds 5μA |
| Clamping Voltage | 26.0V @ 115.4A - limits voltage seen by downstream circuitry during surge |
| Breakdown Voltage | 17.8–19.7V @ 1.0mA - precise avalanche onset range ensures predictable turn-on |
| ESD Rating | 30kV air/contact per IEC-61000-4-2 - protects against human-hand electrostatic discharge |
| Operating Temperature | -55°C to +150°C - supports under-hood automotive environments |
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 (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground during overvoltage |
| Anode | Reference/ground return | Typically tied to system ground plane; completes clamping path during avalanche |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use with PPAP support and change control traceability |
| Glass-passivated die | Enhances long-term reliability and stability of breakdown voltage under thermal cycling |
| Lead-free & halogen-free | Complies with RoHS 3 (2015/863/EU) and Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb) |
| Low clamping ratio | VC/VRWM = 1.625 - tight voltage margin preserves headroom for 24V system ICs |
Applications
| Automotive Power Input Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: 12V/24V battery-fed infotainment head unit exposed to ISO 7637-2 Pulse 1 (−150V/50ms) and Pulse 3a/b (±100V fast transients). IC Role / Device Role / Timing Role: Primary clamping device placed upstream of DC-DC converter input, triggered within nanoseconds to limit rail voltage excursion. Use Value: Clamps to 26.0V, preventing damage to 36V-rated buck controller and preserving system uptime during cold-crank events. |
Use Scenario: Digital input module in factory automation PLC subjected to inductive kickback from 24V solenoid switching. IC Role / Device Role / Timing Role: Parallel-connected TVS across input terminal pair, shunting surge energy away from optocoupler input stage. Use Value: Absorbs 3000W peak pulses without degradation, ensuring >100,000-cycle reliability in high-noise manufacturing environments. |
| Telecom PoE Interface Protection | Medical Equipment DC Rail Protection |
Use Scenario: 48V Power over Ethernet (IEEE 802.3af/at) port on network switch facing lightning-induced surges on data pairs. IC Role / Device Role / Timing Role: Paired unidirectional TVS on each data line (MDI), referenced to common-mode ground, clamping differential and common-mode transients. Use Value: 26.0V clamping enables safe interface with 30V-tolerant PHY ICs while meeting IEC 61000-4-5 Level 4 requirements. |
Use Scenario: 5V/12V internal DC rails in portable ultrasound imaging device requiring immunity to ESD from operator touch and cable coupling. IC Role / Device Role / Timing Role: Point-of-load TVS adjacent to FPGA or ADC power pins, providing localized suppression of fast-rising transients. Use Value: 30kV IEC-61000-4-2 rating prevents latch-up or parametric shift in precision analog front-end components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-Q | 600W rating, same VRWM/VC but lower IPP (57.7A); SMC package replaced by smaller SMB | Not suitable for 3000W ISO 7637-2 Pulse 5a (load dump); limited to lower-energy transients | Select only if space-constrained and surge energy is ≤600W |
| SMCJ16A | Same 3000W rating and SMC package, but lacks AEC-Q101 qualification and automotive change control | Acceptable for industrial/commercial use; not approved for automotive production BOMs requiring PPAP | Choose for cost-sensitive non-automotive designs where qualification is not mandated |
Compared with SMBJ16A-Q and SMCJ16A, the 3.0SMCJ16AQ-13 uniquely delivers full AEC-Q101 compliance, 3000W surge capacity in SMC form factor, and guaranteed automotive-grade traceability - making it the only option qualified for safety-critical vehicle subsystems.

FAQ
What does the 'Q' suffix signify in 3.0SMCJ16AQ-13?
The 'Q' suffix indicates AEC-Q101 qualification, meaning the device has passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life required for automotive electronics. It also confirms production in IATF 16949-certified facilities with full PPAP documentation support.
Can 3.0SMCJ16AQ-13 be used in bidirectional configurations?
No - the 'A' in the part number denotes unidirectional polarity, confirmed by the cathode band marking and electrical specs (e.g., forward surge current rating applies only to uni-directional units). For bidirectional protection, select the 'CA' variant (e.g., 3.0SMCJ16CA-13), which lacks polarity marking and supports symmetrical clamping.
How does thermal derating affect its 3000W rating?
The 3000W peak pulse power is specified at +25°C ambient; Fig. 1 in DS30818 shows linear derating to ~1500W at +125°C. This must be accounted for in high-temperature enclosures - e.g., under-hood ECUs require layout with ≥8mm² copper pour and thermal vias to maintain effective junction temperature below 150°C.
Is this device compatible with lead-free reflow soldering profiles?
Yes - it is qualified for standard lead-free reflow (J-STD-020), with matte tin-plated leads and moisture sensitivity level 1 (unlimited floor life at ≤30°C/60% RH). Peak reflow temperature up to 260°C is supported, and the UL 94V-0 mold compound withstands multiple thermal cycles without delamination.
