Product details
Overview
SMBG160A-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power rails and signal lines. It features a 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), <2.3 µA reverse leakage at VWM, and clamps to ≤259 V at 2.3 A peak pulse current - deployed in automotive power modules, industrial motor drives, and telecom DC-DC input stages.
For engineers reviewing the SMBG160A-E3/52 datasheet, SMBG160A-E3/52 pinout, SMBG160A-E3/52 application, or SMBG160A-E3/52 equivalent, key selection criteria include its AEC-Q101 qualification, DO-215AA (SMBG) surface-mount package, unidirectional polarity with cathode band marking, and compliance with UL 497B for protector classification - all critical for automotive-grade surge immunity design and IEC 61000-4-5 level 4 system validation.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below 160 V and rapidly avalanches above ~178 V to limit transient energy. Its glass-passivated junction ensures stable breakdown characteristics and low dynamic impedance under repetitive surge conditions.
Designed for 10/1000 µs waveform compliance, it delivers 600 W peak pulse power with 0.01% duty cycle derating, supports 100 A non-repetitive forward surge (8.3 ms half-sine), and maintains operation across –55 °C to +150 °C junction temperature - enabling use in under-hood automotive environments and industrial power supplies with thermal cycling stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC rail margin for 12 V–48 V systems. |
| VBR (min/max) | 178 V / 197 V at 1 mA - precise avalanche onset range ensures predictable turn-on without premature conduction. |
| VC @ IPPM | ≤259 V at 2.3 A - clamping voltage limits downstream IC stress during 600 W transients (e.g., ISO 7637-2 Pulse 1/2/5a). |
| IPPM | 2.3 A - peak pulse current capability under 10/1000 µs waveform; directly determines protected circuit's surge withstand level. |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves battery life in always-on automotive modules and sensor nodes. |
| TJ max | +150 °C - enables placement near hot components (e.g., MOSFETs, inductors) without thermal derating penalties. |
| Package | SMBG (DO-215AA) - industry-standard 2-pin gull-wing SMT footprint with 5.0 mm × 5.0 mm copper pad requirement for thermal dissipation. |
Pinout & Package
SMBG160A-E3/52 uses the SMBG (DO-215AA) surface-mount package: a low-profile, gull-wing leaded case with cathode identification via molded band. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and qualified to MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage return path; forms clamping loop with cathode to shunt surge current safely to GND. |
| Cathode | High-side transient input | Connected to protected line (e.g., 12 V battery rail); marked by visible band; conducts avalanche current when VAK exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and ADAS power domains - meets stress test requirements for temperature cycling, HTRB, and ESD. |
| 600 W peak pulse power (10/1000 µs) | Withstands ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 surges up to 4 kV (line-earth) without degradation. |
| Glass passivated junction | Ensures stable VBR tolerance (<±5%), low leakage drift over time, and resistance to humidity-induced parameter shift. |
| UL 497B recognized (QVGQ2) | Approved for use in telecom and industrial protectors requiring third-party safety certification for surge suppression circuits. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profiles without baking - simplifies SMT manufacturing and reduces production risk. |
Applications
| Automotive Power Rail Protection | Industrial DC-DC Input Stage |

IC Role / Device Role / Timing Role: Localized TVS on 15 V auxiliary supply rail feeding gate driver ICs and position sensors. Use Value: Fast response (<1 ns) and low clamping voltage prevent false triggering or latch-up in sensitive analog front-ends and digital isolators. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/52 | Same VWM/VBR specs but rated for 600 W with 10/1000 µs waveform and lower RθJA (85 °C/W vs. 100 °C/W); identical SMB (DO-214AA) footprint. | Preferred where board space allows larger SMB package and higher thermal margin is needed for sustained surge duty cycles. | Select SMBJ160A-E3/52 if layout permits DO-214AA and thermal performance is prioritized over compactness. |
| SMCJ160A-E3/52 | Same electrical specs but in larger SMC (DO-214AB) package; rated for 1500 W peak pulse power and higher IFSM (200 A vs. 100 A). | Suitable for high-energy industrial surge environments (e.g., factory automation mains interfaces) where 600 W is insufficient. | Choose SMCJ160A-E3/52 when protecting against IEC 61000-4-5 10 kV/5 kA tests or repeated heavy-duty transients. |
Compared with SMBJ160A-E3/52 and SMCJ160A-E3/52, SMBG160A-E3/52 offers the smallest footprint (DO-215AA) and highest board density - ideal for space-constrained automotive modules - while retaining full AEC-Q101 qualification and UL 497B recognition at 600 W rating.

FAQ
What is the maximum clamping voltage of SMBG160A-E3/52 under a 10/1000 µs surge?
The SMBG160A-E3/52 has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current of 2.3 A under the standardized 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88456 and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is SMBG160A-E3/52 suitable for automotive applications?
Yes, SMBG160A-E3/52 is AEC-Q101 qualified and UL 497B recognized (file E136766), making it suitable for automotive applications including engine control units, body control modules, and ADAS power domains. Its –55 °C to +150 °C operating junction temperature range, glass-passivated junction, and validated reliability testing meet stringent automotive environmental and lifetime requirements.
What does the "-E3/52" suffix indicate in SMBG160A-E3/52?
The "-E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads; "/52" specifies packaging in 7″ diameter plastic tape and reel with a base quantity of 750 units. This ordering code aligns with Vishay's standard logistics configuration for automated SMT assembly and ensures compatibility with pick-and-place equipment calibrated for DO-215AA devices.
How does SMBG160A-E3/52 differ from bidirectional TVS diodes like SMBG160CA?
SMBG160A-E3/52 is unidirectional and features a cathode band for polarity-sensitive placement, while SMBG160CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The unidirectional version provides lower leakage (<1.0 µA vs. ≤2.0 µA for CA types) and is preferred for DC rail protection; bidirectional variants suit AC-coupled or floating signal line applications.
What is the thermal resistance of SMBG160A-E3/52, and how does it affect layout?
SMBG160A-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 during repetitive surges, PCB layout must adhere to this pad size and use internal ground planes or thermal vias - undersized pads will cause excessive temperature rise and premature failure.
