Product details
Overview
3.0SMCJ16A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) designed for primary overvoltage protection on DC power rails and signal lines. It features a 16.0V reverse standoff voltage (VRWM), 17.8–19.7V breakdown voltage (VBR) at 1.0mA test current, and clamps transients to ≤26.0V at 115.4A peak pulse current under 10/1000μs waveform.
For engineers reviewing the 3.0SMCJ16A-13 datasheet, 3.0SMCJ16A-13 pinout, 3.0SMCJ16A-13 application, or 3.0SMCJ16A-13 equivalent, this device is selected for robust ESD and surge immunity in industrial power supplies, automotive body electronics, PoE-powered equipment, and I/O interface protection where fast response (<1ns), low clamping ratio (VC/VRWM ≈ 1.63), and AEC-Q200-compatible reliability are required.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by avalanche breakdown above its VRWM. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<5µA at VRWM), while the SMC package enables high thermal dissipation during 3000W 10/1000μs pulses.
The unidirectional configuration includes a cathode band for polarity identification and supports DC-biased applications only. It meets IEC-61000-4-2 Level 4 ESD (30kV air/30kV contact), HBM 8kV, CDM 1kV, and MM 800V, with operating junction temperature range of –55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10/1000μs surges up to 115.4A without failure |
| Reverse Standoff Voltage (VRWM) | 16.0V - maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage (VBR) | 17.8–19.7V @ 1.0mA - precise avalanche initiation threshold for predictable clamping onset |
| Clamping Voltage (VC) | ≤26.0V @ 115.4A - limits downstream circuit stress to safe levels during surge events |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - protects against human-handling discharge |
| Operating Temperature | –55°C to +150°C - suitable for under-hood automotive and industrial ambient conditions |
| Package | SMC (DO-214AB) - surface-mount footprint with 0.21g mass and UL 94V-0 flammability rating |
Pinout & Package
Package: SMC (DO-214AB), molded plastic, matte tin-plated leads, cathode band marking for unidirectional polarity. Dimensions: 5.59–6.22mm (A), 6.60–7.11mm (B), 2.75–3.18mm (C); weight ≈ 0.21g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node in unidirectional clamp configuration |
| Cathode | High-side surge input terminal | Connected to protected line; avalanche conduction occurs from cathode to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 3000W peak pulse rating | Enables protection against severe lightning-induced surges (IEC 61000-4-5 Level 4) on 24V/48V systems |
| Glass-passivated die | Ensures long-term VBR stability and low parameter drift across temperature and lifetime |
| RoHS-compliant & halogen-free | Meets EU Directive 2015/863/EU with <900ppm Br, <900ppm Cl, <1000ppm Sb - supports green manufacturing |
| JEDEC-qualified reliability | Validated to high-reliability standards per AEC-Q200 references - suitable for automotive-grade BOMs |
| Moisture sensitivity Level 1 | Eliminates bake requirements prior to reflow; compatible with standard SMT assembly processes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-13 (Diodes Inc.) | Lower peak power (600W), same VRWM and VBR, SMB package (smaller footprint, lower thermal mass) | Not suitable for IEC 61000-4-5 Level 4 or repeated surge events; limited to light-duty ESD/surge | Select when board space is constrained and surge energy is ≤600W; verify thermal derating at >75°C ambient |
| 1.5SMC16A (ON Semiconductor) | Same SMC package and 16V rating, but 1500W peak power and higher clamping voltage (27.5V @ 54.5A) | Higher VC reduces margin for 3.3V/5V IC protection; requires larger safety margin in design | Choose if legacy qualification or dual-sourcing is required; confirm clamping headroom for sensitive loads |
Compared with SMBJ16A-13 and 1.5SMC16A, the 3.0SMCJ16A-13 delivers double the surge energy handling of the SMBJ and tighter clamping than the 1.5SMC, making it optimal for high-reliability 24V/48V industrial and automotive power rail protection where sustained 3000W capability and low VC/VRWM ratio are critical.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ16A-13 under standard test conditions?
The maximum clamping voltage (VC) is 26.0V when subjected to a 115.4A peak pulse current under the standardized 10/1000μs waveform per IEC 61000-4-5. This value is measured at TA = +25°C with specified PCB pad layout (8.00mm² copper area), and decreases slightly at lower temperatures due to negative TC of avalanche voltage.
Is the 3.0SMCJ16A-13 suitable for bidirectional signal line protection?
No - the "A" suffix denotes unidirectional configuration with a cathode band; it conducts only during positive transients on the cathode relative to anode. For bidirectional protection (e.g., AC lines or differential buses), the "CA" variant (e.g., 3.0SMCJ16CA-13) must be used, which has symmetrical breakdown in both polarities and no polarity marking.
Does the 3.0SMCJ16A-13 meet automotive qualification standards?
While not AEC-Q200 certified out-of-box, this part is manufactured in IATF 16949-certified facilities and qualified to JEDEC high-reliability standards referenced in AEC-Q. Automotive-grade equivalents (e.g., 3.0SMCJ16AQ-13) with full PPAP documentation and AEC-Q200 testing are available through Diodes' automotive product line.
How does the SMC package affect thermal performance compared to SMA or SMB?
The SMC (DO-214AB) package offers ~2.5× the thermal mass and ~3× the copper pad area capability of SMA (DO-214AC), enabling higher surge energy absorption and reduced junction temperature rise during 3000W pulses. Its 0.21g mass and optimized leadframe improve heat spreading versus smaller packages, supporting reliable operation at +125°C ambient with proper PCB layout.
