Product details
Overview
LSR106 L0G from Taiwan Semiconductor is a 1 A, 60 V repetitive peak reverse voltage Schottky surface-mount rectifier in MELF package, with 25 A surge rating, 0.70 V max forward voltage at 1.0 A, and 80 pF typical junction capacitance - used in high-efficiency DC/DC converters requiring low-loss unidirectional conduction.
For engineers reviewing the LSR106 L0G datasheet, LSR106 L0G pinout, LSR106 L0G application, or LSR106 L0G equivalent, key selection criteria include VRRM=60 V, IFSM=25 A, TJ(max)=+150°C, VF(max)=0.70 V @ 1 A, and MELF package thermal performance (RθJA=80°C/W).
Technical Context
This Schottky rectifier operates as a unidirectional power switching device with metal–semiconductor junction for low forward voltage drop and fast recovery. Its MELF construction enables high thermal dissipation and mechanical robustness in compact layouts.
Designed for continuous 1 A DC forward current and transient 25 A surge (8.3 ms half-sine), it maintains reverse leakage ≤1 mA at 25°C and ≤10 mA at 125°C under rated 60 V blocking, with junction capacitance optimized at 80 pF for high-frequency converter operation.

| TJ(max) | +150°C - supports operation in thermally constrained industrial power modules |
| RθJA | 80°C/W - defines thermal rise from junction to ambient under standard PCB mounting |

FAQ
What is the maximum junction temperature rating for LSR106 L0G?
The LSR106 L0G has a maximum junction temperature (TJ(max)) of +150°C, validated per absolute maximum ratings table in the official TSC datasheet revision H2004. This rating enables reliable operation in thermally demanding environments such as enclosed industrial converters or motor drive auxiliary supplies where ambient temperatures exceed 85°C. The LSR106 L0G must be derated per the forward current derating curve above 25°C ambient.
Does LSR106 L0G have a specified forward voltage at 1 A?
Yes, the LSR106 L0G specifies a maximum forward voltage (VF) of 0.70 V at IF = 1.0 A and TA = 25°C, as confirmed in the Electrical Specifications table (page 2, H2004). This value is measured under pulse conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal design. The LSR106 L0G's low VF contributes directly to reduced power dissipation in high-duty-cycle applications.
Is LSR106 L0G RoHS and halogen-free compliant?
Yes, the LSR106 L0G is fully RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Features section of the TSC datasheet (H2004). This compliance applies to all materials in the MELF package, including molding compound and metallization. The LSR106 L0G meets environmental requirements for export to EU, Japan, and other regulated markets.
What is the surge current rating of LSR106 L0G?
The LSR106 L0G is rated for a non-repetitive peak forward surge current (IFSM) of 25 A, tested per JEDEC standard with an 8.3 ms single half-sine waveform superimposed on rated load. This rating is confirmed in the Absolute Maximum Ratings table (page 1, H2004). The LSR106 L0G maintains this surge capability across its full operating temperature range, supporting robustness in adapter and inverter applications subject to line transients.
What package type does LSR106 L0G use, and how is polarity marked?
The LSR106 L0G uses a MELF (Metal Electrode Leadless Face) cylindrical surface-mount package. Polarity is marked by a single black cathode band on one end cap, as documented in the Mechanical Data section (page 1, H2004). The MELF outline dimensions (A = 4.80–5.50 mm, B = 2.25–2.67 mm) and suggested pad layout are provided in the Package Outline Dimensions diagram (page 4, H2004). The LSR106 L0G has no leads or pins - terminals are the metallized end faces.
