Product details
Overview
SMB10J16-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 16 V stand-off voltage (VWM), 1000 W peak pulse power (10/1000 µs), 26.0 V maximum clamping voltage at 38.5 A peak surge current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMB10J16-E3/5B datasheet, SMB10J16-E3/5B pinout, SMB10J16-E3/5B application, or SMB10J16-E3/5B equivalent, this device is selected for robust overvoltage protection in automotive ECUs, industrial sensor interfaces, and DC power input stages where fast response (<1 ns), low clamping ratio (VC/VWM ≈ 1.625), and MSL Level 1 solderability are critical.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, triggering when reverse voltage exceeds its 17.8–19.7 V breakdown range (VBR at 1 mA). Its unidirectional polarity enables integration into polarized DC circuits without series blocking components.
Thermal performance is defined by RθJA = 72 °C/W and RθJL = 20 °C/W, supporting operation up to 150 °C junction temperature. The device meets J-STD-020 MSL Level 1 and passes JESD201 Class 1A whisker testing, confirming suitability for lead-free reflow assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets upper limit for protected circuit's nominal DC rail. |
| VBR (min/max) | 17.8 V / 19.7 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on margin above VWM. |
| VC @ IPPM | 26.0 V - Clamped voltage at 38.5 A peak surge (10/1000 µs); defines worst-case overvoltage seen by downstream ICs during ESD or load dump. |
| PPPM | 1000 W - Peak pulse power handling capability; supports protection against ISO 7637-2 Pulse 5a (load dump) in 12 V automotive systems. |
| IPPM | 38.5 A - Peak surge current corresponding to VC; used with PCB trace impedance to estimate actual clamping level under system-level transients. |
| TJ max | 150 °C - Maximum junction temperature; enables use in under-hood automotive environments with minimal derating at 85 °C ambient. |
| Package | DO-214AA (SMB) - Standard surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with automated pick-and-place and IR/reflow. |
Pinout & Package
DO-214AA (SMB) package: two-terminal SMD device with cathode indicated by a color band on the body. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD22-B102. Mounting requires 5.0 mm × 5.0 mm copper pads per terminal per Vishay recommended layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or lowest potential point in protected circuit; forms return path for surge current. |
| Cathode | Protected line input | Connected to the line being protected (e.g., 12 V supply rail); avalanche conduction occurs from cathode to anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensors per stress test requirements. |
| MSL Level 1 rating | Zero floor life limitation; supports unlimited exposure to ambient conditions prior to reflow, eliminating bake requirements. |
| Glass-passivated junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives, critical for harsh-environment reliability. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT bursts), improving protection margin for sensitive gate drivers and ADC inputs. |
| 1000 W peak pulse power | Enables single-device protection against severe transients such as ISO 16750-2 load dump (up to 35 V, 100 ms) when combined with appropriate upstream impedance. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery-fed ECU power input subjected to load dump (ISO 7637-2 Pulse 5a) and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND, clamping transients before they reach DC-DC converters and microcontrollers. Use Value: Limits voltage to ≤26.0 V during 38.5 A surge events, preventing latch-up or permanent damage to 3.3 V/5 V logic supplies downstream. |
Use Scenario: Analog output line of a pressure sensor exposed to cable discharge events (IEC 61000-4-2) in factory automation. IC Role / Device Role / Timing Role: TVS connected across signal and ground, absorbing sub-100 ns ESD pulses before reaching op-amp input stage. Use Value: Sub-1 ns response time and 26.0 V clamping ensure sensor output remains within ±0.5% full-scale error during 8 kV contact discharge. |
| DC Motor Drive Flyback Suppression | Telecom DC Power Feeding Protection |
Use Scenario: H-bridge motor driver with inductive flyback spikes exceeding 60 V during PWM switching in HVAC actuators. IC Role / Device Role / Timing Role: TVS mounted across motor terminals or power rail, conducting flyback energy into ground during MOSFET turn-off. Use Value: 1000 W pulse rating sustains repeated 10/1000 µs spikes at 10 Hz frequency without thermal runaway or parameter drift. |
Use Scenario: -48 V DC feeding line in telecom base station equipment vulnerable to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Unidirectional TVS installed at power entry point, shunting induced common-mode transients to chassis ground. Use Value: 16 V VWM allows stable operation under normal -48 V bias while clamping positive surges to safe levels for downstream PoE controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/5B | Same VWM (16 V), identical DO-214AA package, but rated for 600 W PPPM (vs. 1000 W). | Limited to lower-energy transients (e.g., IEC 61000-4-5 Level 3) rather than automotive load dump. | Select when cost sensitivity outweighs need for full 1000 W surge margin and thermal derating is acceptable. |
| 1.5SMC16A | Same VWM and VC, but in larger DO-214AB (SMC) package with 1500 W PPPM and higher IPPM (62.5 A). | Better suited for high-current industrial surge environments where board space permits larger footprint. | Choose when system-level testing reveals marginal clamping margin with SMB10J16-E3/5B and additional surge headroom is required. |
Compared with SMBJ16A-E3/5B, SMB10J16-E3/5B delivers 67% higher pulse power in the same SMB footprint; versus 1.5SMC16A, it offers identical electrical protection in 40% less PCB area but with reduced thermal mass for rapid transient absorption.

FAQ
What is the breakdown voltage range for SMB10J16-E3/5B?
The SMB10J16-E3/5B has a guaranteed breakdown voltage (VBR) range of 17.8 V to 19.7 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This ensures reliable turn-on above its 16 V stand-off voltage while maintaining sufficient margin against normal operating fluctuations. The exact VBR for a given SMB10J16-E3/5B unit falls within this range and is verified during production screening.
Is SMB10J16-E3/5B suitable for automotive applications?
Yes, SMB10J16-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including engine control modules, body control units, and ADAS sensor interfaces. Its construction includes glass-passivated junction, MSL Level 1 moisture sensitivity, and JESD201 Class 1A whisker resistance - all validated per automotive stress test requirements. The SMB10J16-E3/5B datasheet confirms compliance with AEC-Q101 Rev D.
What is the maximum clamping voltage of SMB10J16-E3/5B under surge conditions?
The SMB10J16-E3/5B clamps to a maximum of 26.0 V when subjected to its rated 38.5 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This clamping voltage is measured at the device terminals under specified test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads), and represents the worst-case overvoltage imposed on protected circuitry during transient events.
Does SMB10J16-E3/5B have polarity markings?
Yes, SMB10J16-E3/5B is a unidirectional TVS diode with cathode indicated by a distinct color band on the device body. The banded end connects to the protected line (e.g., 12 V rail), while the unbanded end connects to ground. No marking is present on bi-directional variants, but SMB10J16-E3/5B is strictly unidirectional as confirmed by its part number suffix "A" and electrical characteristics table.
What is the thermal resistance from junction to ambient for SMB10J16-E3/5B?
The SMB10J16-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes still air convection and is used to calculate steady-state temperature rise under continuous power dissipation - though the device is intended for transient, not continuous, power handling.
