Product details
Overview
SMBJ13CHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown range at 1 mA test current, 21.5 V maximum clamping voltage at 27.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and signal lines of industrial motor drives.
For engineers reviewing the SMBJ13CHE3/52 datasheet, SMBJ13CHE3/52 pinout, SMBJ13CHE3/52 application, or SMBJ13CHE3/52 equivalent, key selection criteria include clamping performance under 27.9 A surge, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, unidirectional polarity marking, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (VBR), it avalanches rapidly to divert surge current away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable leakage (<1.0 µA at 13 V) and repeatable clamping behavior across temperature.
The device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine), supports -55 °C to +150 °C operating junction temperature, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak - confirming suitability for high-reliability industrial and automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before significant leakage; defines safe working margin below clamping onset |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - precise avalanche initiation window ensuring predictable turn-on during transients |
| VC @ IPPM | 21.5 V at 27.9 A - clamping voltage under 600 W 10/1000 µs surge; limits stress on protected 12 V logic or gate drivers |
| PPPM | 600 W - peak pulse power handling capacity; validates protection against IEC 61000-4-5 Level 3 surges |
| IFSM | 100 A - single half-sine surge rating (8.3 ms); supports protection of MOSFETs during inductive switching events |
| TJ max | +150 °C - maximum junction temperature; enables operation in enclosed industrial enclosures without derating |
| RθJA | 100 °C/W - thermal resistance junction-to-ambient on standard 0.2" × 0.2" pads; informs board-level thermal design |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified (HE3 suffix). Cathode indicated by band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |

| 600 W peak pulse power (10/1000 µs) | Withstands repeated lightning-induced surges per IEC 61000-4-5 without degradation |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes overvoltage overshoot during fast transients, protecting 3.3 V/5 V logic interfaces |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow without moisture-related popcorning or delamination |
| Glass passivated junction | Ensures stable leakage (<1 µA) and long-term reliability under humidity and thermal cycling |

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-E3/52 | Commercial-grade (non-AEC-Q101), same VWM/VBR/VC, identical SMB package | Lacks automotive qualification; suitable for industrial/commercial designs without automotive compliance needs | Select when AEC-Q101 is not required and cost optimization is prioritized |
| SMAJ13AHE3/A | Lower power rating (400 W), SMA package (smaller footprint), higher RθJA (150 °C/W) | Reduced surge handling; limited to lower-energy transients or space-constrained layouts | Choose only if board area is critical and peak surge energy remains below 400 W capability |
Compared with SMBJ13A-E3/52, the SMBJ13CHE3/52 adds AEC-Q101 qualification without sacrificing clamping performance; versus SMAJ13AHE3/A, it delivers 50 % higher pulse power and better thermal dissipation in the same production flow - making it optimal for automotive and high-reliability industrial deployments.

FAQ
What is the clamping voltage of SMBJ13CHE3/52 at its rated peak pulse current?
The SMBJ13CHE3/52 has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 27.9 A, measured using a 10/1000 µs waveform. This value ensures protected circuits remain within safe operating limits during standardized surge events. The SMBJ13CHE3/52 maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMBJ13CHE3/52 qualified for automotive applications?
Yes, SMBJ13CHE3/52 is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3". This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its use in automotive body electronics, powertrain subsystems, and infotainment power rails. The SMBJ13CHE3/52 meets these requirements without derating.
What is the standoff voltage (VWM) and why is it critical for SMBJ13CHE3/52 selection?
The SMBJ13CHE3/52 has a standoff voltage (VWM) of 13 V - the maximum continuous reverse voltage it can block without significant leakage (<1.0 µA). This parameter ensures reliable operation on nominal 12 V systems, providing sufficient margin above normal rail voltage while avoiding premature conduction. Selecting SMBJ13CHE3/52 for 12 V applications guarantees no false triggering during ripple or load transients.
How does the SMBJ13CHE3/52 package compare to SMAJ or SMC variants in terms of thermal performance?
The SMBJ13CHE3/52 uses the SMB (DO-214AA) package, offering a thermal resistance (RθJA) of 100 °C/W on standard 5.0 mm × 5.0 mm copper pads - superior to the SMAJ's 150 °C/W and competitive with SMC's ~80 °C/W. This allows SMBJ13CHE3/52 to sustain higher average power dissipation in compact layouts. Its SMB footprint balances surge capability, thermal efficiency, and SMT manufacturability better than smaller or larger alternatives.
Can SMBJ13CHE3/52 replace bidirectional TVS diodes like SMBJ13CA in circuit designs?
No - SMBJ13CHE3/52 is unidirectional and cannot replace bidirectional types such as SMBJ13CA without circuit modification. The SMBJ13CHE3/52 conducts only in reverse bias (cathode-to-anode), whereas SMBJ13CA clamps in both polarities. Substituting SMBJ13CHE3/52 in AC-coupled or floating signal lines would leave positive transients unprotected. Always verify polarity requirements before selecting SMBJ13CHE3/52.
