Product details
Overview
SMBJ16C-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 standoff voltage (VWM), 17.8–19.7 V breakdown voltage (VBR) at 1 mA, 26.0 V maximum clamping voltage (VC) at 23.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in industrial sensor interfaces and DC power rail protection.
For engineers reviewing the SMBJ16C-E3/52 datasheet, SMBJ16C-E3/52 pinout, SMBJ16C-E3/52 application, or SMBJ16C-E3/52 equivalent, key selection criteria include unidirectional polarity, 1.0 µA max reverse leakage at VWM, 150 °C max junction temperature, and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly.
Technical Context
This TVS diode operates as a voltage-clamping protector: under normal conditions it presents high impedance (>1 GΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, limiting downstream voltage to ≤26.0 V. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
The device uses a single PN junction structure with cathode-band marking, rated for 100 A non-repetitive forward surge (8.3 ms half-sine), and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Thermal resistance is 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working range. |
| VBR (min/max) | 17.8 V / 19.7 V at 1 mA - Confirmed breakdown threshold range; ensures reliable triggering above VWM. |
| VC @ IPPM | 26.0 V at 23.1 A - Clamped voltage during 600 W transient; determines protected circuit's maximum stress level. |
| IPPM | 23.1 A - Peak pulse current supported with 10/1000 µs waveform; defines surge handling capacity. |
| PPPM | 600 W - Peak pulse power dissipation capability; validates suitability for IEC 61000-4-5 Level 4 surges. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in industrial ambient environments up to +85 °C with derating. |
| Leakage @ VWM | 1.0 µA - Ultra-low reverse leakage ensures minimal standby power loss in battery-powered systems. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads. Cathode identified by molded band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when overvoltage occurs. |
| Anode (unbanded end) | Reference node | Typically tied to system ground or lower-potential rail; completes clamping path during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 surge events without thermal runaway. |
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress. |
| MSL Level 1, 260 °C peak reflow | Enables compatibility with standard lead-free SMT processes without pre-baking. |
| RoHS-compliant, commercial grade (E3 suffix) | Meets global environmental compliance requirements for industrial and consumer electronics. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving clamping precision. |
Applications
| Industrial Sensor Interface | DC Power Rail Protection |
|---|---|
|
Use Scenario: Protecting analog output lines of pressure/temperature sensors exposed to motor switching noise in factory automation cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and MCU ADC input to clamp ESD and inductive kickback. Use Value: Limits transient voltage to ≤26.0 V, preventing ADC saturation and protecting 3.3 V or 5 V input stages without adding series resistance. |
Use Scenario: Safeguarding 12 V or 24 V DC input rails of PLC modules against load dump and relay contact bounce. IC Role / Device Role / Timing Role: Parallel-connected TVS across input terminals to shunt surge energy before reaching upstream regulators and controllers. Use Value: Absorbs 600 W pulses while maintaining clamped voltage below 26.0 V, preserving downstream 36 V-rated components. |
| Automotive Body Control Module | Consumer USB Power Port |
|
Use Scenario: Input protection for LIN bus transceivers and window motor drivers in non-safety-critical automotive subsystems. IC Role / Device Role / Timing Role: Unidirectional suppression on 12 V supply lines feeding microcontrollers and driver ICs. Use Value: Withstands 100 A surge (8.3 ms) and meets AEC-Q101 qualification when ordered as HE3 variant - this E3 version supports cost-sensitive designs. |
Use Scenario: Overvoltage guard on 5 V USB Type-A power pins in smart speakers and set-top boxes subjected to hot-plug and cable discharge events. IC Role / Device Role / Timing Role: Standoff-rated TVS placed directly at USB connector to intercept CDM/ESD transients before USB controller IC. Use Value: 1.0 µA leakage at 16 V ensures no impact on USB suspend current; 26.0 V clamping prevents damage to 5 V tolerant PHYs. |
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-E3/52 | Same VWM (16 V), identical VBR and VC specs; differs only in marking code (no "C" suffix). | No functional difference; "C" suffix denotes Vishay internal revision control, not electrical distinction. | Select SMBJ16C-E3/52 when matching documented BOMs referencing the "C"-suffixed variant. |
| SMAJ16A-E3/52 | Lower PPPM (400 W vs. 600 W); same VWM/VBR but higher VC (32.4 V @ 12.4 A); SMA package (smaller footprint, higher RθJA). | Less robust for high-energy surges; unsuitable where IEC 61000-4-5 Level 4 compliance is required. | Choose SMBJ16C-E3/52 over SMAJ16A-E3/52 when 600 W surge margin, lower clamping, or thermal performance on PCB copper pads is critical. |
Compared with SMBJ16A-E3/52, SMBJ16C-E3/52 offers identical electrical protection but traceable revision control; versus SMAJ16A-E3/52, it delivers 50 % higher pulse power, 20 % lower clamping voltage, and superior thermal dissipation due to larger SMB package and lower RθJA.

FAQ
What is the polarity configuration of SMBJ16C-E3/52?
SMBJ16C-E3/52 is a unidirectional TVS diode: it conducts only when the cathode is at a higher potential than the anode. The molded band on the SMB package identifies the cathode terminal. This configuration provides asymmetric clamping ideal for DC power lines and single-ended signal paths where reverse voltage is not expected.
Does SMBJ16C-E3/52 meet automotive qualification standards?
SMBJ16C-E3/52 itself is RoHS-compliant commercial-grade (E3 suffix) and not AEC-Q101 qualified. However, Vishay offers the functionally identical SMBJ16CH-E3/52 (HE3 suffix) variant with full AEC-Q101 qualification for automotive applications. Engineers requiring automotive-grade assurance must specify the HE3 version, not SMBJ16C-E3/52.
What is the maximum clamping voltage of SMBJ16C-E3/52 and under what test condition?
The maximum clamping voltage of SMBJ16C-E3/52 is 26.0 V, measured at a peak pulse current (IPPM) of 23.1 A using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can SMBJ16C-E3/52 be used in bidirectional signal line protection?
No - SMBJ16C-E3/52 is unidirectional and unsuitable for bidirectional AC or differential signal lines. For such applications, Vishay specifies bidirectional variants with "CA" suffix (e.g., SMBJ16CA-E3/52), which exhibit symmetrical clamping in both directions and lack polarity marking. Using SMBJ16C-E3/52 on bidirectional lines risks forward conduction and failure.
What is the thermal resistance and recommended pad layout for SMBJ16C-E3/52?
SMBJ16C-E3/52 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. To maintain safe junction temperatures under repetitive surges, use minimum recommended pad dimensions and avoid excessive trace length or isolation that increases thermal impedance.
