Product details
Overview
SMB10J16A-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 26.0 V clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMB10J16A-E3/52 datasheet, SMB10J16A-E3/52 pinout, SMB10J16A-E3/52 application, or SMB10J16A-E3/52 equivalent, key selection criteria include clamping performance under 100 A IFSM surge, AEC-Q101 qualification for automotive use, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ps) and low incremental surge resistance, enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced transients (IEC 61000-4-5). Its thermal resistance (RθJA = 72 °C/W) and junction temperature limit (TJ max = 150 °C) support sustained operation in enclosed automotive ECUs and industrial PLC modules.
The device operates within -55 °C to +150 °C ambient range and meets MSL level 1 per J-STD-020 (260 °C peak reflow). Polarity is marked by cathode band; terminals are solderable per J-STD-002 and JESD 22-B102, with whisker resistance per JESD 201 Class 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping initiates; defines safe DC rail margin for 12 V automotive systems. |
| VBR min/max | 17.8 V / 19.7 V at 1.0 mA - guaranteed breakdown threshold ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 26.0 V at 38.5 A - clamping voltage limits downstream IC stress during 1000 W transient surges. |
| PPPM | 1000 W (10/1000 µs) - peak power handling capacity for short-duration load dump or inductive switching spikes. |
| IFSM | 100 A (8.3 ms half-sine) - surge current rating supports robust protection against repetitive motor drive transients. |
| Leakage ID | 1.0 µA at VWM - ultra-low reverse leakage preserves battery life in always-on automotive modules. |
| Package | SMB (DO-214AA) - surface-mount footprint (4.57 mm × 3.94 mm) compatible with standard pick-and-place and reflow profiles. |
Pinout & Package
Package: SMB (DO-214AA), molded epoxy case meeting UL 94 V-0; matte tin-plated leads; cathode indicated by color band.

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
|
Use Scenario: 12 V battery feed to body control module (BCM) exposed to load dump (ISO 16750-2) and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamps positive surges to ground while blocking reverse current during normal operation. Use Value: Limits voltage seen by downstream LDOs and microcontrollers to ≤26.0 V, preventing latch-up or oxide damage. |
Use Scenario: Analog output line (0–5 V) from pressure sensor in factory automation PLC, subject to ESD and cable discharge events. IC Role / Device Role / Timing Role: Fast-response TVS shunts transient energy before it reaches ADC input or op-amp buffer stage. Use Value: Clamps 8 kV contact ESD (IEC 61000-4-2) within <1 ns, preserving signal integrity and measurement accuracy. |
| DC Motor Drive Feedback Protection | Telecom Power Supply Rail Protection |
|
Use Scenario: Hall-effect position feedback line from BLDC motor driver, vulnerable to inductive kickback during PWM switching. IC Role / Device Role / Timing Role: Bidirectional clamping not applicable; unidirectional SMB10J16A-E3/52 protects only positive-going transients on grounded-return lines. Use Value: Withstands 100 A surge (IFSM) and repeated 38.5 A pulses (IPPM), ensuring long-term reliability in motor control enclosures. |
Use Scenario: +48 V primary input rail in telecom base station power converter, subjected to lightning-induced surges (IEC 61000-4-5). IC Role / Device Role / Timing Role: Front-end TVS absorbs bulk surge energy before it reaches active rectification and regulation stages. Use Value: 1000 W PPPM rating handles 10/1000 µs surges up to 400 V, reducing stress on upstream MOVs and downstream MOSFETs. |
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 SMB package, but lower PPPM (600 W) and higher VC (28.8 V at 24.7 A). | Lower surge capacity suits consumer-grade power supplies where 1000 W is not required. | Select SMBJ16A-E3/52 only if system-level surge testing confirms 600 W sufficiency and layout allows tighter thermal management. |
| 1.5SMC16A-E3/57 | Higher power (1500 W), same VWM (16 V), but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm). | Requires PCB area increase; suited for industrial UPS or solar inverters needing higher energy absorption. | Choose 1.5SMC16A-E3/57 when 1000 W margin is insufficient and board space permits larger footprint. |
Compared with SMBJ16A-E3/52 and 1.5SMC16A-E3/57, SMB10J16A-E3/52 delivers optimal balance of 1000 W surge capability, AEC-Q101 qualification, and compact SMB footprint - making it the preferred choice for space-constrained automotive and industrial designs requiring validated reliability.

FAQ
What is the clamping voltage of SMB10J16A-E3/52 and how is it measured?
The SMB10J16A-E3/52 has a maximum clamping voltage (VC) of 26.0 V at 38.5 A peak pulse current (IPPM), tested with a 10/1000 µs waveform per ANSI/IEEE C62.35. This value represents the upper voltage limit imposed on the protected circuit during a standardized surge event, directly measured across the device terminals under specified test conditions - critical for verifying safe operation of downstream ICs like microcontrollers or CAN transceivers in the SMB10J16A-E3/52-protected system.
Is SMB10J16A-E3/52 suitable for automotive applications?
Yes, SMB10J16A-E3/52 is AEC-Q101 qualified and explicitly listed in Vishay's automotive ordering codes (HE3/HM3 suffix variants). Its construction - glass-passivated junction, MSL Level 1 rating, -55 °C to +150 °C operating range, and 100 A IFSM surge rating - meets requirements for engine control units, body electronics, and ADAS sensors. The E3 suffix denotes RoHS-compliant commercial grade, and full automotive qualification is confirmed in Document Number 88422 - making SMB10J16A-E3/52 appropriate for production automotive designs.
What does the "-E3/52" suffix mean in SMB10J16A-E3/52?
The "-E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads; "/52" specifies packaging in 7-inch diameter plastic tape and reel, with 750 units per reel. This format aligns with standard SMT assembly logistics and ensures compatibility with high-speed pick-and-place equipment. The E3/52 configuration is distinct from HM3 (halogen-free) or HE3 (AEC-Q101 qualified) variants - confirming SMB10J16A-E3/52 is optimized for cost-sensitive industrial and consumer applications where full automotive qualification is not required.
How does SMB10J16A-E3/52 compare to bidirectional TVS diodes like SMB8J16CA?
SMB10J16A-E3/52 is unidirectional and rated for 1000 W PPPM, whereas SMB8J16CA is bidirectional with 800 W PPPM and identical VWM (16 V) and VC (26.0 V). The unidirectional SMB10J16A-E3/52 provides superior surge handling for DC rails with defined polarity (e.g., 12 V to GND), while SMB8J16CA protects AC-coupled or floating lines. SMB10J16A-E3/52 also supports higher IFSM (100 A vs. no IFSM rating for bidirectional types), making it preferable for power-line protection where forward surge current is a concern.
What PCB layout guidance applies to SMB10J16A-E3/52 for optimal thermal and electrical performance?
Vishay specifies mounting SMB10J16A-E3/52 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated PPPM and thermal resistance (RθJA = 72 °C/W). Trace width should be ≥1.0 mm, and thermal vias (≥4× 0.3 mm diameter) are recommended under each pad to enhance heat dissipation. Avoid placing sensitive traces near the cathode-anode path, and maintain ≥1.5 mm creepage distance to adjacent conductors - especially critical for SMB10J16A-E3/52 deployments in 48 V telecom or 24 V industrial systems.
