Product details
Overview
SMBJ13CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 13 V standoff voltage (VWM), 21.5 V maximum clamping voltage (VC) at 27.9 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and telecom equipment.
For engineers reviewing the SMBJ13CAHE3/5B datasheet, SMBJ13CAHE3/5B pinout, SMBJ13CAHE3/5B application, or SMBJ13CAHE3/5B equivalent, key selection considerations include bidirectional surge suppression capability, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector with symmetrical breakdown behavior in both directions due to its bidirectional construction. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes.
The SMBJ13CAHE3/5B is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and delivers 600 W transient power handling under repetitive 0.01% duty cycle conditions - validated with 10/1000 µs standard test waveform.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR min/max | 14.4 V / 15.9 V at 1.0 mA test current - ensures predictable, tight breakdown threshold for reliable transient detection. |
| VC @ IPPM | 21.5 V at 27.9 A - clamping voltage during 600 W surge; limits downstream voltage stress to protected circuitry. |
| IPPM | 27.9 A - peak pulse current capability with 10/1000 µs waveform; determines survivability against defined surge events. |
| PPPM | 600 W - peak pulse power rating; sets energy absorption capacity for transient suppression without failure. |
| TJ max | +150 °C - maximum junction temperature; supports operation in high-ambient industrial and automotive under-hood environments. |
| RθJA | 100 °C/W - thermal resistance junction-to-ambient; informs PCB pad design requirements for sustained power dissipation. |
Pinout & Package

FAQ
What is the clamping voltage of SMBJ13CAHE3/5B at its rated peak pulse current?
The SMBJ13CAHE3/5B has a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current of 27.9 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures protected circuits remain below critical voltage thresholds during surge events. The SMBJ13CAHE3/5B maintains this clamping performance across its full operating temperature range of -55 °C to +150 °C.
Is SMBJ13CAHE3/5B suitable for automotive applications?
Yes, SMBJ13CAHE3/5B is AEC-Q101 qualified, meaning it has passed rigorous stress tests for automotive-grade reliability including temperature cycling, high-temperature reverse bias, and mechanical shock. Its bidirectional architecture and 21.5 V clamping make it appropriate for protecting CAN, LIN, and sensor signal lines in body control modules and ADAS systems. The SMBJ13CAHE3/5B meets OEM requirements for under-hood and cabin-mounted electronics.
How does the SMBJ13CAHE3/5B differ from unidirectional SMBJ13AHE3/5B?
The SMBJ13CAHE3/5B is bidirectional with symmetrical breakdown in both polarities, while the SMBJ13AHE3/5B is unidirectional and conducts only in reverse bias. This makes SMBJ13CAHE3/5B ideal for AC-coupled or floating lines like RS-485 or CAN, whereas SMBJ13AHE3/5B suits DC power rails where polarity is fixed. Both share identical VWM (13 V), VC (21.5 V), and PPPM (600 W), but SMBJ13CAHE3/5B has no cathode band marking.
What PCB layout guidance applies to SMBJ13CAHE3/5B for optimal surge performance?
For optimal surge performance, SMBJ13CAHE3/5B must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power. Short, wide traces to ground reduce inductance and prevent VC overshoot; thermal vias under pads improve heat dissipation. The SMBJ13CAHE3/5B datasheet specifies these dimensions to ensure compliance with IEC 61000-4-5 Level 4 testing conditions.
Does SMBJ13CAHE3/5B meet RoHS and REACH requirements?
Yes, SMBJ13CAHE3/5B is RoHS-compliant per EU Directive 2011/65/EU and satisfies REACH SVHC screening requirements.
