Product details
Overview
SMBJ16-E3/5B 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 standoff 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 used to protect MOSFETs and sensor interfaces in industrial motor drives.
For engineers reviewing the SMBJ16-E3/5B datasheet, SMBJ16-E3/5B pinout, SMBJ16-E3/5B application, or SMBJ16-E3/5B 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 protector: under normal conditions it presents high impedance (>1 GΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
The device is rated for repetitive 10/1000 µs surges at 0.01% duty cycle, with derating above 25 °C per Fig. 2, and supports operating junction temperatures from –55 °C to +150 °C. It meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 when ordered with HE3/HM3 suffixes - not applicable to SMBJ16-E3/5B.
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 at 1.0 mA test current - guaranteed breakdown onset window; determines minimum overvoltage threshold for protection activation |
| VC @ IPPM | 26.0 V at 23.1 A - clamped voltage during 600 W transient; directly limits stress on downstream ICs or MOSFETs |
| IPPM | 23.1 A (10/1000 µs) - peak surge current capability; defines maximum transient energy the device can absorb without failure |
| PPPM | 600 W - peak pulse power rating; enables robust protection against inductive switching spikes and ESD-like events |
| RθJA | 100 °C/W - junction-to-ambient thermal resistance; dictates required PCB copper area (0.2" × 0.2") for reliable power dissipation |
| Leakage ID | 1.0 µA max at VWM - ensures minimal standby power loss and no interference with low-current sensor biasing |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Polarity marked by cathode band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; connected to protected circuit ground or low-side reference | Provides return path for surge current; must be routed with low-inductance trace to minimize clamping overshoot |
| Cathode | Current exit terminal during reverse-biased clamping; connected to line being protected (e.g., 16 V rail) | Acts as high-impedance node until VBR exceeded; band marking identifies this terminal for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 16 V supply rails |
| 26.0 V clamping voltage at 23.1 A | Limits voltage seen by downstream 30 V-rated MOSFETs to within safe SOA, preventing avalanche-induced failure |
| Glass passivated chip junction | Ensures stable VBR tolerance (±5%) and long-term reliability under thermal cycling and humidity exposure |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free SMT processes without pre-baking; eliminates moisture-related popcorning risk |
| RoHS-compliant, commercial grade (E3 suffix) | Meets EU RoHS Directive 2011/65/EU and JEDEC JESD201 Class 2 whisker resistance for high-volume manufacturing |
Applications

|
Use Scenario: Secondary-side overvoltage suppression on 15–19 V DC output rails of AC/DC adapters powering IoT hubs and set-top boxes. IC Role / Device Role / Timing Role: Standoff-clamp TVS placed between VOUT and GND to suppress flyback spikes from poorly regulated SMPS stages. Use Value: 16 V VWM provides 1–3 V margin above nominal output, while 26.0 V VC prevents damage to 3.3 V/5 V LDOs and USB controllers downstream. |
Use Scenario: Input protection for 24 V digital input channels receiving signals from external sensors and switches in factory automation systems. IC Role / Device Role / Timing Role: Front-end transient suppressor on each channel's input trace, located before optocoupler or Schmitt trigger input stage. Use Value: 1.0 µA leakage at 16 V ensures no false triggering of high-impedance input circuits; fast response time (<1 ns) captures nanosecond-scale EFT bursts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/5B | Same electrical specs and package; identical marking code "LP" per datasheet Table 1; functionally identical part number variant | No functional difference - same unidirectional configuration, VWM, VC, and surge rating | Select SMBJ16A-E3/5B only if legacy BOM references "A" suffix; SMBJ16-E3/5B is the current preferred designation per Vishay ordering guide |
| SMBJ16CA-E3/5B | Bidirectional version: symmetric VBR (17.8–19.7 V), same VC (26.0 V), but no polarity marking; higher ID (2.0 µA) at VWM | Required for AC-coupled or dual-polarity signal lines (e.g., RS-485, CAN); unsuitable for DC power rail protection where polarity matters | Choose SMBJ16CA-E3/5B only when protecting bidirectional data lines; SMBJ16-E3/5B remains optimal for 16 V DC supply clamping |
Compared with SMBJ16A-E3/5B (identical performance, legacy marking) and SMBJ16CA-E3/5B (bidirectional, higher leakage), SMBJ16-E3/5B delivers optimized unidirectional clamping for 16 V DC systems with lowest leakage and industry-standard polarity identification - critical for error-free SMT placement and deterministic protection behavior.

FAQ
What is the breakdown voltage range for SMBJ16-E3/5B?
The SMBJ16-E3/5B has a guaranteed breakdown voltage (VBR) range of 17.8 V to 19.7 V at 1.0 mA test current, per Vishay Document 88392, Table 1. This range ensures consistent clamping onset across production lots and allows design margining for worst-case overvoltage scenarios in 16 V systems. The SMBJ16-E3/5B maintains this specification under standard test conditions (TA = 25 °C).
Is SMBJ16-E3/5B suitable for automotive applications?
The SMBJ16-E3/5B is a commercial-grade, RoHS-compliant part (E3 suffix) and is not AEC-Q101 qualified. For automotive use, Vishay specifies the SMBJ16HE3_B variant (HE3 suffix), which undergoes additional stress testing and qualification. The SMBJ16-E3/5B may be used in non-safety-critical aftermarket or infotainment subsystems, but SMBJ16-E3/5B itself does not meet automotive reliability standards.
What is the maximum clamping voltage of SMBJ16-E3/5B and at what current?
The SMBJ16-E3/5B has a maximum clamping voltage (VC) of 26.0 V at a peak pulse current (IPPM) of 23.1 A, measured using the standardized 10/1000 µs double-exponential waveform. This value is critical for determining whether downstream components - such as 30 V MOSFETs or 28 V LDOs - remain within their absolute maximum ratings during surge events. The SMBJ16-E3/5B achieves this clamping performance with low incremental resistance.
Does SMBJ16-E3/5B have polarity marking, and how is it oriented on the PCB?
Yes, SMBJ16-E3/5B is unidirectional and features a cathode band marking on the SMB (DO-214AA) package body. The banded end corresponds to the cathode terminal and must be connected to the line being protected (e.g., +16 V rail), while the unbanded end connects to ground. Incorrect orientation renders the device ineffective for positive transients. The SMBJ16-E3/5B datasheet confirms this polarity convention in the Mechanical Data section.
What is the thermal resistance and recommended PCB layout for SMBJ16-E3/5B?
The SMBJ16-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay Document 88392. To maintain reliability under repetitive surges, designers must implement this pad layout - smaller pads increase thermal impedance and risk junction overheating. The SMBJ16-E3/5B's RθJL is 20 °C/W, confirming lead conduction dominates heat transfer.
