Product details
Overview
3.0SMCJ13A-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 13V reverse standoff voltage, 14.4V minimum breakdown voltage, and 21.5V maximum clamping voltage at 139.5A peak pulse current. It provides robust ESD protection per IEC-61000-4-2 (30kV air/contact), HBM (8kV), and CDM (1kV), and is used in DC power rail protection for industrial motor drives and telecom power supplies.
For engineers reviewing the 3.0SMCJ13A-13 datasheet, 3.0SMCJ13A-13 pinout, 3.0SMCJ13A-13 application, or 3.0SMCJ13A-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 SMC package solderability per MIL-STD-202.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias (VRWM = 13V), leakage remains ≤5μA; during transients, it avalanches at VBR ≥14.4V and clamps to ≤21.5V at IPP = 139.5A (10/1000μs). Its glass-passivated junction ensures stable breakdown and low capacitance.
Designed for single-pulse surge suppression, it supports 3000W peak power per JEDEC-standard non-repetitive 8.3ms half-sine wave (uni-directional only) and derates linearly above +25°C ambient per Fig. 1 - e.g., 75% power at +75°C. Operating junction temperature range is –55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10/1000μs surge without failure; defines maximum energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 13V - maximum continuous DC or RMS voltage before significant leakage; sets operating rail compatibility |
| Breakdown Voltage (VBR) | 14.4–15.9V @ 1.0mA - guaranteed avalanche onset range; ensures reliable triggering above system nominal voltage |
| Clamping Voltage (VC) | 21.5V @ 139.5A - maximum voltage seen by protected circuit during rated surge; determines IC survivability margin |
| ESD Rating | 30kV air / 30kV contact per IEC-61000-4-2 - qualifies for front-panel and connector-level electrostatic discharge immunity |
| Operating Temperature | –55°C to +150°C - enables use in under-hood automotive, industrial PLC, and outdoor telecom environments |
| Package | SMC (DO-214AB) - surface-mount outline with 6.9mm pad width; supports automated assembly and 3000pcs/reel tape-and-reel handling |
Pinout & Package

Applications
| Industrial Motor Drive DC Bus Protection | Telecom 48V Power Input Protection |
|---|---|
Use Scenario: Suppresses switching spikes and load-dump transients on 24–48V DC bus lines feeding IGBT gate drivers and MCU power rails. IC Role / Device Role / Timing Role: Shunt clamping device triggered within nanoseconds of overvoltage event; limits bus voltage to safe level for downstream silicon. Use Value: Prevents catastrophic failure of 3.3V/5V logic supplies and gate drivers during 100A+ inductive kickback events. |
Use Scenario: Guards primary 48V input stage of telecom base station power modules against lightning-induced surges and hot-swap transients. IC Role / Device Role / Timing Role: Fast-acting voltage clamp placed upstream of DC-DC converters; absorbs up to 3000W for 10/1000μs duration. Use Value: Maintains converter uptime by limiting input voltage excursion to ≤21.5V during 139.5A surge, preserving MOSFET and controller integrity. |
| Automotive Body Control Module (BCM) Power Rail | Factory Automation I/O Terminal Protection |
Use Scenario: Protects 12V supply rail in BCMs against load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS connected between battery rail and ground; clamps to 21.5V while diverting >130A surge current. Use Value: Ensures microcontroller and CAN transceiver survival during 35V/100ms load dump events without requiring bulk capacitance buffering. |
Use Scenario: Shields digital I/O terminals (24V PLC inputs) from ESD and inductive switching noise in factory floor environments. IC Role / Device Role / Timing Role: Localized clamping element mounted directly at connector entry point; responds in <1ns to fast transients. Use Value: Reduces false triggering and latch-up in optocoupler-isolated inputs by limiting common-mode voltage excursions to <22V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-13 (Diodes Inc.) | Lower peak power (600W), same VRWM/VC, SMB package (smaller footprint, lower thermal mass) | Suitable for low-energy signal lines or space-constrained PCBs; insufficient for 48V bus-level surge | Select when board area is critical and surge energy is ≤600W (e.g., sensor interface, low-power MCU I/O) |
| 1.5SMC13A (ON Semiconductor) | Same SMC package and 13V rating, but 1500W peak power and higher VC = 23.2V @ 65A | Acceptable for moderate-energy applications but offers less clamping margin and lower surge current headroom | Choose only if legacy design reuse is required and 3000W headroom is not needed; verify VC margin vs. protected IC abs max |
Compared with SMBJ13A-13 and 1.5SMC13A, the 3.0SMCJ13A-13 delivers 2× higher surge current capacity (139.5A vs. ≤65A) and tighter clamping (21.5V vs. ≥23.2V), making it uniquely suited for high-reliability 48V/24V power rail protection where energy absorption and voltage margin are critical.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ13A-13 under rated surge conditions?
The maximum clamping voltage (VC) is 21.5V at 139.5A peak pulse current, measured using the standardized 10/1000μs double-exponential waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during surge events.
Is the 3.0SMCJ13A-13 suitable for bidirectional signal line protection?
No - the "A" suffix indicates unidirectional configuration with cathode band marking. For bidirectional protection (e.g., AC lines or differential buses), the "CA" variant (e.g., 3.0SMCJ13CA-13) must be used, which has symmetrical breakdown in both polarities and no polarity indicator.
How does thermal derating affect the 3.0SMCJ13A-13's surge capability above +25°C ambient?
Per Figure 1 in DS30818 Rev. 18, peak pulse power derates linearly: at +75°C ambient, capability drops to 75% (2250W); at +125°C, it falls to 40% (1200W). Engineers must adjust expected IPP accordingly - e.g., 139.5A at +25°C reduces to ~105A at +75°C for the same waveform.
Does the 3.0SMCJ13A-13 meet automotive qualification standards?
The standard 3.0SMCJ13A-13 is JEDEC-qualified for high reliability but not AEC-Q200 certified. Diodes offers automotive-grade equivalents with "Q" suffix (e.g., 3.0SMCJ13AQ-13) that undergo PPAP, IATF 16949 manufacturing, and full AEC-Q200 stress testing - required for under-hood or safety-critical vehicle systems.
