Product details
Overview
SMBG160-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for robust overvoltage protection of power rails and signal lines. It features 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR), 600 W peak pulse power (10/1000 µs), <2.3 A maximum reverse leakage at VWM, and clamps transients to ≤259 V at 2.3 A peak pulse current.
For engineers reviewing the SMBG160-E3/52 datasheet, SMBG160-E3/52 pinout, SMBG160-E3/52 application, or SMBG160-E3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, RoHS-compliant matte tin terminations, MSL Level 1 rating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 160 V and rapidly transitions to low-impedance conduction above VBR (min 178 V, max 197 V at 1 mA test current), limiting transient voltages to ≤259 V at rated IPPM. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for single-polarity DC protection, SMBG160-E3/52 supports repetitive surge events at 0.01% duty cycle and handles non-repetitive 8.3 ms half-sine surges up to 100 A (IFSM). Thermal resistance is RθJA = 100 °C/W (on recommended pad layout) and RθJL = 20 °C/W, enabling reliable operation up to TJ = +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR (min/max) | 178 V / 197 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on across production lot. |
| VC @ IPPM | ≤259 V at 2.3 A - Clamped voltage during 10/1000 µs surge; determines protected circuit's maximum transient exposure. |
| PPPM | 600 W - Peak pulse power handling (10/1000 µs waveform); validates suitability for IEC 61000-4-5 Level 4 surges. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports inrush or fault-current events in power supplies. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive or industrial environments. |
| MSL Level | Level 1 (per J-STD-020) - No floor life limitation; compatible with standard reflow profiles up to 260 °C peak. |

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 (160 V), identical DO-214AA (SMB) package but slightly larger footprint (4.57 mm × 3.94 mm vs. 6.48 mm × 3.94 mm); lower PPPM = 600 W same, but VC = 259 V (same), IPPM = 2.3 A (same). | Requires PCB layout change due to different package outline (DO-214AA vs. DO-215AA); not pin-compatible despite same pin count. | Select SMBJ160A-E3/52 only if existing design uses SMB footprint and thermal pad area permits lower RθJA (85 °C/W typical). |
| SMBG160HE3/52 | Identical electrical specs and DO-215AA package, but AEC-Q101 qualified version (HE3 suffix); same RoHS compliance and termination finish. | No functional difference; intended for automotive OEM programs requiring full qualification documentation traceability. | Choose SMBG160HE3/52 when AEC-Q101 certification evidence (test reports, PPAP) is contractually required for vehicle integration. |
Compared with SMBJ160A-E3/52, SMBG160-E3/52 offers superior thermal performance in constrained layouts due to its wider body and lower RθJA derating curve; versus SMBG160HE3/52, it provides identical protection capability at lower cost where automotive qualification is not mandated.

FAQ
What is the polarity configuration of SMBG160-E3/52?
SMBG160-E3/52 is a unidirectional transient voltage suppressor diode. Its cathode is marked by a band on the package body, and it conducts only when the cathode is biased positive relative to the anode-making it suitable for DC rail protection where polarity is fixed. This differs from bi-directional variants (e.g., SMBG160CA) which suppress surges regardless of polarity.
Does SMBG160-E3/52 meet automotive reliability standards?
SMBG160-E3/52 is RoHS-compliant and manufactured to commercial-grade specifications. While it shares the DO-215AA package and core electrical specs with AEC-Q101-qualified variants like SMBG160HE3/52, the -E3/52 suffix itself denotes commercial grade-not automotive-qualified. For automotive use, specify SMBG160HE3/52 instead.
What is the maximum clamping voltage for SMBG160-E3/52 under surge conditions?
The maximum clamping voltage (VC) for SMBG160-E3/52 is 259 V, measured at the peak pulse current (IPPM) of 2.3 A using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can SMBG160-E3/52 be used in high-humidity or harsh-environment applications?
Yes-SMBG160-E3/52 features a glass-passivated silicon junction and molding compound rated UL 94 V-0, providing excellent moisture resistance and insulation integrity. Its operating junction temperature range of –55 °C to +150 °C and MSL Level 1 rating further support deployment in industrial enclosures and outdoor telecom equipment.
What is the recommended PCB pad layout for SMBG160-E3/52?
Vishay specifies a minimum 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pad for each terminal to achieve rated thermal performance (RθJA = 100 °C/W). The DO-215AA outline drawing confirms 0.155″ (3.94 mm) terminal width and 0.255″ (6.48 mm) overall length; maintaining these dimensions ensures optimal heat dissipation and mechanical reliability during reflow.
