Product details
Overview
SMBJ16-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage (VC) at 23.1 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform), commonly deployed to protect MOSFETs and ICs in industrial power supplies.
For engineers reviewing the SMBJ16-E3/52 datasheet, SMBJ16-E3/52 pinout, SMBJ16-E3/52 application, or SMBJ16-E3/52 equivalent, key selection criteria include unidirectional polarity, 1.0 µA max reverse leakage at VWM, 17.8–19.7 V breakdown voltage range (VBR), thermal resistance of 100 °C/W (junction-to-ambient), and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly.
Technical Context
This TVS diode operates as a fast-acting shunt clamp, entering avalanche conduction when transient voltage exceeds its breakdown threshold (VBR = 17.8–19.7 V). Its low incremental surge resistance ensures minimal voltage overshoot during 10/1000 µs surges up to 23.1 A, while maintaining stable clamping at 26.0 V under rated conditions.
The device uses a glass-passivated silicon junction and is rated for -55 °C to +150 °C operating junction temperature. It meets MSL Level 1 per J-STD-020 with 260 °C peak reflow profile, and its SMB package provides mechanical robustness and UL 94 V-0 flammability compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 17.8 V / 19.7 V - Breakdown voltage range at 1.0 mA test current; determines precise clamping onset threshold. |
| VC @ IPPM | 26.0 V - Clamped voltage at 23.1 A peak pulse current; directly limits stress on downstream protected components. |
| PPPM | 600 W - Peak pulse power handling capability with 10/1000 µs waveform; quantifies transient energy absorption capacity. |
| IPPM | 23.1 A - Maximum non-repetitive peak pulse current; sets absolute surge current limit under standard test condition. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance; governs self-heating under sustained power dissipation. |
| Leakage (ID) | 1.0 µA max at VWM - Reverse leakage current; ensures minimal standby power loss and signal integrity in high-impedance circuits. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/52 | Same electrical specs and package; identical marking code "LP" and VBR range (17.8–19.7 V); differs only in suffix convention (A vs. no suffix). | No functional difference; both rated for commercial-grade operation with RoHS/E3 compliance. | Select SMBJ16A-E3/52 if legacy BOM references "A" suffix; otherwise SMBJ16-E3/52 is functionally interchangeable. |
| SMCJ16A-E3/52 | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package; higher PPPM = 1500 W and IPPM = 59.3 A. | Better suited for higher-energy transients; requires larger PCB footprint and different pad layout. | Choose SMCJ16A-E3/52 only when 600 W is insufficient and board space allows SMC footprint. |
Compared with SMBJ16A-E3/52, SMBJ16-E3/52 offers identical protection performance in the same SMB package, while SMCJ16A-E3/52 trades compactness for 2.5× higher surge capacity-making SMBJ16-E3/52 optimal for space-constrained 600 W-class designs.

FAQ
What is the breakdown voltage range of SMBJ16-E3/52?
The SMBJ16-E3/52 has a guaranteed breakdown voltage (VBR) range of 17.8 V to 19.7 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures consistent clamping behavior across manufacturing lots and enables reliable design margining above its 16 V stand-off voltage. The SMBJ16-E3/52 maintains this specification across its full operating temperature range of -55 °C to +150 °C.
Is SMBJ16-E3/52 suitable for automotive applications?
SMBJ16-E3/52 is a commercial-grade part (RoHS-compliant, E3 suffix) and not AEC-Q101 qualified. For automotive use, Vishay offers the SMBJ16HE3 variant (AEC-Q101 qualified, HE3 suffix) with identical electrical parameters but additional stress testing. The SMBJ16-E3/52 may be used in non-safety-critical automotive subsystems only after full system-level validation, but SMBJ16HE3 is required for qualified BCM or infotainment designs.
What is the maximum clamping voltage of SMBJ16-E3/52 under surge conditions?
The SMBJ16-E3/52 exhibits a maximum clamping voltage (VC) of 26.0 V when subjected to its rated 23.1 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C on specified copper pad layout and remains stable across its operational temperature range due to low temperature coefficient (0.089 %/°C) of VBR. The SMBJ16-E3/52 delivers predictable voltage limiting essential for protecting 24 V logic interfaces.
Does SMBJ16-E3/52 have bidirectional capability?
No, SMBJ16-E3/52 is a unidirectional TVS diode, indicated by the absence of "CA" suffix (e.g., SMBJ16CA would be bidirectional). Its cathode band marks the terminal that sinks transient current to ground during positive overvoltage events. For bidirectional protection-such as AC line or data-line applications-engineers must select the CA-suffixed variant or pair unidirectional devices in opposing configuration. The SMBJ16-E3/52 is optimized for DC rail protection where polarity is fixed.
What packaging and reel options are available for SMBJ16-E3/52?
SMBJ16-E3/52 is supplied in 7-inch plastic tape-and-reel format (package code "52") with 750 units per reel, compliant with EIA-481 standards. Lead finish is matte tin, qualified to J-STD-002 and JESD 22-B102 for solderability, and meets JESD 201 Class 2 whisker resistance. The SMBJ16-E3/52 is also available in 13-inch reels (code "5B", 3200 units) for high-volume SMT lines, with identical electrical and mechanical specifications across both formats.
