概要

Description

SMBJ48A-E3/52 is a surface-mount transient-voltage-suppressor (TVS) diode in the SMB package. It’s designed to protect a 48 V power rail from surges and transients.
- Configuration: unidirectional (A) TVS in SMB (DO-214AA) package.
- Typical use: protect telecom, data, automotive, and 48 V power-supply lines from lightning, induction, and wiring transients.
- What the suffix means: “48A” indicates nominal 48 V-class devices; “E3/52” is a manufacturer/package/revision code (exact electrical data (VRWM, VBR, VCL, IPP) varies by supplier).
- Key electrical data: exact VRWM, breakdown, clamping voltage, and peak pulse power depend on the specific vendor’s datasheet for this suffix; commonly around 600 W peak pulse power in 8/20 μs, with VRWM around the low-40 V to ~46 V range for a 48 V class device.
- How to use: connect cathode to the protected line and anode to ground; add proper PCB layout and, if needed, series fusing.
For precise specs, refer to the vendor’s SMBJ48A-E3/52 datasheet.

Features

SMBJ48A-E3/52 is a bidirectional TVS diode in the SMBJ package. Key features:
- VRWM (stand-off) about 48 V
- Peak pulse power: ~600 W (8/20 μs)
- Breakdown voltage roughly in the 53–60 V range; clamps around ~75–85 V at IPP
- Very fast response time (sub-nanosecond to nanosecond)
- Wide operating temperature: typically -55°C to +150°C
- RoHS-compliant, lead-free; E3/52 denotes packaging (tape & reel) for automated assembly
- Suitable for protecting 48 V systems and I/O lines in automotive/industrial applications
- SMD SMBJ packaging for easy surface-mount protection
Note: exact VBR and clamp values vary within the datasheet tolerances; consult the datasheet for precise specifications and packaging details.

Package

SMBJ48A-E3/52 uses the SMB package (DO-214AB), a standard surface‑mount TVS diode package.

Pinout

Pin count: 2 (two-terminal device).
Function: A unidirectional SMBJ TVS diode (transient-voltage suppressor) rated for ~48 V, used to clamp voltage spikes on the line and protect power supplies/circuits from surges and ESD.

Manufacturer

- Manufacturer: Littelfuse.
- Company type: A global electronics components company focused on fuses and circuit-protection devices (including TVS diodes).

Application

SMBJ48A-E3/52 is a unidirectional SMBJ TVS diode used to clamp surges on 48V DC rails. Typical application areas: automotive 48V systems and e-mobility; telecom and datacom power rails; industrial controls and drives; solar/battery management and power-supply input protection; any 48–60V DC lines needing transient suppression. Suitable for protecting DC–DC converters, power adapters, and I/O lines from surges, ESD, and power faults.
