Product details
Overview
3.0SMCJ16CA-13 from Diodes Incorporated is a bi-directional 3000W surface-mount transient voltage suppressor (TVS) designed for 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, and IEC-61000-4-2 ESD rating of 30kV (air/contact). It is used in industrial power supplies and automotive infotainment interfaces to absorb lightning-induced surges and ESD events.
For engineers reviewing the 3.0SMCJ16CA-13 datasheet, 3.0SMCJ16CA-13 pinout, 3.0SMCJ16CA-13 application, or 3.0SMCJ16CA-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, peak pulse current handling under 10/1000μs waveform, bi-directional symmetry for AC-coupled lines, and SMC package thermal performance on 8mm² copper land.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias (≤16V), it draws ≤5μA leakage; when transient exceeds breakdown (17.8–19.7V @ 1mA), it avalanches to clamp voltage ≤26.0V within nanoseconds. Its glass-passivated junction ensures stable breakdown and low capacitance.
The device is rated for 3000W peak pulse power (10×1000μs waveform), supports -55°C to +150°C operating range, and meets JEDEC high-reliability standards. Bi-directional construction eliminates polarity concerns in differential or AC signal paths, unlike uni-directional variants with cathode band marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10/1000μs transients without failure, enabling robust surge immunity in 24V/48V industrial systems |
| Reverse Standoff Voltage (VRWM) | 16.0V - maximum continuous DC or RMS voltage before significant leakage; sets upper limit for protected line voltage |
| Breakdown Voltage (VBR) | 17.8–19.7V @ 1mA - guaranteed avalanche onset range; defines minimum overvoltage threshold for clamping activation |
| Clamping Voltage (VC) | 26.0V @ 115.4A - maximum voltage seen by downstream circuit during full-rated surge; determines IC survivability margin |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-body and system-level electrostatic discharge events |
| Operating Temperature | -55°C to +150°C - qualified for under-hood automotive and industrial environments with wide thermal cycling |
| Package | SMC (DO-214AB) - surface-mount outline with 6.9mm × 4.4mm pad layout; supports 3000W dissipation via 8mm² copper land |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA-13 (Diodes Inc.) | Same VRWM and VC, but 600W peak power (vs. 3000W); SMB package (smaller thermal mass) | Limited to lower-energy transients (e.g., HBM ESD only); unsuitable for IEC 61000-4-5 surges | Select when board space is constrained and surge threat level is Class 2 or lower |
| 1.5SMC16CA (ON Semiconductor) | Identical VRWM (16V), VC (26.0V), and 3000W rating; same SMC package; minor VBR spread (17.8–19.8V vs. 17.8–19.7V) | Direct functional replacement with identical footprint and electrical behavior; qualified to AEC-Q101 | Preferred for automotive designs requiring AEC-Q101 qualification and PPAP documentation |
Compared with SMBJ16CA-13, 3.0SMCJ16CA-13 delivers five times higher surge energy handling; versus 1.5SMC16CA, it offers identical clamping performance but differs in manufacturer-specific process control and automotive qualification status.

FAQ
What is the maximum clamping voltage of 3.0SMCJ16CA-13 under full-rated surge current?
The maximum clamping voltage (VC) is 26.0V at 115.4A 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 represents the highest voltage imposed on protected circuitry during worst-case surge conditions.
Is 3.0SMCJ16CA-13 unidirectional or bidirectional, and how is polarity indicated?
3.0SMCJ16CA-13 is a bi-directional TVS diode with symmetrical breakdown characteristics in both polarities. It has no cathode band or polarity marking-its terminals are functionally interchangeable. This distinguishes it from uni-directional variants like 3.0SMCJ16A-13, which feature a visible cathode band and conduct only in reverse bias.
Can this TVS be used in automotive applications requiring AEC-Q101 qualification?
No-3.0SMCJ16CA-13 is not AEC-Q101 qualified. Diodes Incorporated offers automotive-grade equivalents such as 3.0SMCJ16CQ-13 (Q-suffix), which undergoes additional stress testing, PPAP documentation, and manufacturing in IATF 16949-certified facilities. For automotive use, the Q-suffix variant must be specified.
What PCB layout practices maximize thermal performance for this SMC-packaged TVS?
To ensure rated 3000W pulse handling, mount the device on 8.00mm² (minimum) copper land areas per terminal, using thermal vias to inner or back-side ground planes. Avoid narrow traces between TVS and protected node; keep trace inductance below 10nH to prevent voltage overshoot during fast transients. Follow Diodes' recommended SMC pad layout (C=6.90mm, G=4.40mm).
