Product details
Overview
SMBJ13CH from Taiwan Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy ESD and surge protection in automotive and industrial power rails. It features a 13 V working stand-off voltage (VWM), 14.4–17.6 V breakdown voltage (VBR), 26.0 A peak pulse current (IPP), 23.8 V maximum clamping voltage (VC), and 600 W peak pulse power (PPK) with <1.0 ps response time.
For engineers reviewing the SMBJ13CH datasheet, SMBJ13CH pinout, SMBJ13CH application, or SMBJ13CH equivalent, key selection criteria include clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b, AEC-Q101 qualification status, unidirectional polarity marking, and thermal derating behavior above 25°C ambient.
Technical Context
The SMBJ13CH implements a glass-passivated silicon junction optimized for fast transient suppression in 12 V automotive systems and industrial DC power inputs. Its unidirectional configuration provides reverse-biased clamping only, with forward voltage drop of 3.5 V at 50 A IFSM - consistent with SMBJ5.0H–SMBJ90H device group specifications.
Thermal design relies on RθJC = 10 °C/W and RθJA = 55 °C/W, enabling reliable operation up to TJ = 150 °C. It meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, supporting lead-free reflow assembly without preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 14.4 V / 17.6 V @ IT = 1 mA - Ensures reliable turn-on margin above VWM under production tolerance |
| VC @ IPP | 23.8 V @ 26.0 A - Clamping voltage during 10/1000 µs surge defines protected circuit's worst-case overvoltage |
| PPK | 600 W - Peak power handling capability for standardized transient waveforms per IEC 61000-4-5 |
| ID @ VWM | <1 µA - Low leakage preserves battery life and signal integrity in always-on circuits |
| TJ max | +150 °C - Enables use in under-hood automotive environments and enclosed industrial enclosures |

Applications
| Automotive Power Rail Protection | Industrial DC Input Protection |
|---|---|

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 | Lower VBR range (14.4–15.9 V), lower VC (21.5 V), same PPK and package | Better clamping margin for 12 V systems with tight voltage tolerances | Select SMBJ13A when tighter clamping voltage is prioritized over higher VBR margin |
| SAC13 | Same VWM (13 V), but 400 W PPK, higher VC (27.0 V), DO-214AC (SMA) package | Lower power rating and larger package footprint; not AEC-Q101 qualified | Choose SAC13 only for cost-sensitive non-automotive applications where 600 W surge headroom is unnecessary |
Compared with SMBJ13CH, SMBJ13A offers improved clamping performance at the expense of reduced VBR margin, while SAC13 sacrifices automotive qualification, power rating, and thermal efficiency for lower unit cost in non-critical applications.

FAQ
What is the polarity configuration of SMBJ13CH?
SMBJ13CH is a unidirectional TVS diode, with cathode marked by a band on the DO-214AA (SMB) package body. It clamps only in reverse bias and conducts forward current up to 100 A IFSM. This configuration matches standard 12 V automotive power rail protection layouts where the cathode connects to the protected line and anode to ground.
Does SMBJ13CH meet AEC-Q101 requirements?
Yes, SMBJ13CH is explicitly AEC-Q101 qualified per the manufacturer's documentation. It undergoes stress testing including high-temperature reverse bias (HTRB), temperature cycling, and ESD per AEC-Q101 Rev D, confirming suitability for automotive under-hood and chassis-mounted applications.
What is the maximum clamping voltage of SMBJ13CH under surge conditions?
The maximum clamping voltage VC of SMBJ13CH is 23.8 V at 26.0 A peak pulse current (IPP), measured with a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during standardized surge events and is guaranteed across the full operating temperature range.
How does SMBJ13CH differ from SMBJ13AH?
SMBJ13CH has a VBR range of 14.4–17.6 V and VC = 23.8 V, while SMBJ13AH specifies VBR = 14.4–15.9 V and VC = 21.5 V. The "H" suffix denotes standard breakdown tolerance; "AH" indicates tighter VBR spread and lower clamping, making SMBJ13AH preferable where stricter voltage control is required.
Is SMBJ13CH compatible with lead-free reflow soldering processes?
Yes, SMBJ13CH uses matte tin-plated leads compliant with J-STD-002 and is rated for moisture sensitivity level 1 (MSL-1) per J-STD-020. No floor life limitation or baking is required, and it supports standard Pb-free reflow profiles up to 260 °C peak temperature.
