Diodes Incorporated LT2A07G

Overview

LT2A07G from Diodes Incorporated is a glass passivated general-purpose silicon rectifier diode rated for 1000 V peak reverse voltage and 2.0 A average forward current at TC = 120°C, with 1.1 V forward voltage drop at 2.0 A DC, used in AC/DC power supplies, input rectification stages, and offline SMPS front-ends.

For engineers reviewing the LT2A07G datasheet, LT2A07G pinout, LT2A07G application, or LT2A07G equivalent, key selection criteria include V_RRM = 1000 V, I_(AV) = 2.0 A, V_F = 1.1 V @ 2.0 A, I_FSM = 65 A, and DO-15 package compatibility with through-hole PCB layouts requiring UL 94V-0 compliant insulation.

Technical Context

This device operates as a unidirectional current-conducting junction diode with a planar, glass-passivated silicon chip structure. Its 12 °C/W junction-to-case thermal resistance enables reliable heat dissipation when mounted on copper-clad PCBs or heatsinks under continuous 2.0 A load conditions.

The 40 pF typical junction capacitance (measured at 1.0 MHz, 4.0 V reverse bias) and low 5.0 µA reverse leakage at 25°C support stable performance in high-frequency rectification and low-noise DC bus conditioning applications up to 150°C junction temperature.

FAQ

Is LT2A07G still in production?

No. Diodes Incorporated officially discontinued LT2A07G as of March 2022, designating it obsolete in datasheet DS44017 Rev. 6–4. The active replacement is 2A07G(LS), which shares identical electrical specifications, DO-15 packaging, and RoHS/Green compliance. Inventory at Aetrix Electronics consists of remaining authorized channel stock with full traceability.

What is the maximum allowable case temperature for continuous 2.0 A operation?

The LT2A07G is rated for I_(AV) = 2.0 A at T_C = 120°C, meaning the case (lead termination point) must not exceed 120°C under steady-state conduction. This requires ≥1.5 cm² of 1 oz. copper pour per lead on FR-4 PCBs or use of external heatsinking to maintain junction temperature ≤150°C given its 12 °C/W R_thJC.

Can LT2A07G be used in place of LT2A06G or LT2A05G?

Yes, LT2A07G is backward compatible with LT2A06G (800 V) and LT2A05G (600 V) in the same DO-15 footprint, offering higher V_RRM margin without circuit modification. However, its slightly higher V_F (1.1 V vs. 1.05 V for LT2A05G) increases conduction loss by ~50 mW at 2.0 A, which is negligible in most applications but should be verified in thermally limited designs.

Does LT2A07G meet halogen-free and RoHS requirements?

Yes. LT2A07G is certified "Green" per Diodes Incorporated's definition: <900 ppm bromine, <900 ppm chlorine (<1500 ppm total Br + Cl), and <1000 ppm antimony compounds. It complies with EU RoHS Directives 2011/65/EU and 2015/863/EU, and carries a lead-free, matte-tin plated finish per J-STD-020 moisture sensitivity level MSL-1.
