Product details
Overview
ZLLS2000TC from Diodes Incorporated is a 40V, 2A surface-mount Schottky barrier diode in SOT26 package, featuring 0.54V max forward voltage at 2A and 40µA max reverse leakage at 30V/25°C, optimized for high-frequency rectification and reverse-polarity protection in compact DC-DC converters and mobile charging circuits.
For engineers reviewing the ZLLS2000TC datasheet, ZLLS2000TC pinout, ZLLS2000TC application, or ZLLS2000TC equivalent, key selection criteria include low VF stability across temperature, thermally rated 150°C junction operation, SOT26 pin-compatible dual-anode configuration, and verified leakage performance under 30V bias at elevated ambient conditions.
Technical Context
The ZLLS2000TC integrates two independent Schottky diodes in a single SOT26 package with common cathode terminals (pins 1, 2, 4, 5) and separate anodes (pins 3 and 6), enabling dual-channel reverse protection or synchronous rectification without cross-conduction risk. Its low 65pF capacitance at 30V and 6ns reverse recovery time support switching frequencies beyond 1MHz.
Thermal design is enabled by RθJA = 73°C/W on FR-4 PCB (t < 5s) and 113°C/W in still air, with continuous power dissipation derated linearly above 25°C to zero at 150°C. The device sustains 36A non-repetitive surge current (t ≤ 100µs) and operates across –55°C to +150°C storage range.
Key Specifications

|---|---|
| VRRM | 40 V - Maximum continuous reverse blocking voltage before breakdown |
| IF | 2 A - Continuous forward current rating at 25°C ambient |
| VF Max | 0.54 V @ 2A - Ensures <1.08W conduction loss per diode at full load |
| IR Max | 40 µA @ 30V/25°C - Enables ultra-low standby power loss in battery-backed systems |
| tRR | 6 ns - Supports >10MHz switching with minimal turn-off loss and EMI |
| CD | 65 pF @ 30V/1MHz - Limits capacitive loading on high-speed control nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB240-E3/54 (Vishay) | Single-diode SMC package; 40V/2A; VF = 0.55V @ 2A; IR = 500µA @ 30V | Larger footprint; higher leakage limits use in battery-critical systems | Select when board space allows larger package and leakage tolerance >10× ZLLS2000TC |
| SS24H (ON Semiconductor) | Single-diode SMA package; 40V/2A; VF = 0.52V @ 2A; IR = 500µA @ 30V; no dual-anode option | Requires two devices for dual-path protection; lacks integrated common cathode | Choose only if dual-diode integration is unnecessary and lowest possible VF is primary goal |
Compared with SB240-E3/54 and SS24H, ZLLS2000TC uniquely delivers dual-anode isolation with 10× lower leakage and 40% smaller footprint-critical for multi-rail protection in portable electronics where board area and standby current are constrained.

FAQ
What is the pin configuration of ZLLS2000TC?
ZLLS2000TC uses a SOT26 package with six pins: pins 1, 2, 4, and 5 are internally connected as a common cathode; pin 3 is Anode 1; pin 6 is Anode 2. This dual-anode/common-cathode topology enables independent control of two rectification paths without shared anode parasitics.
Does ZLLS2000TC support automotive applications?
ZLLS2000TC itself is not qualified to AEC-Q101; however, the automotive-grade variant ZLLS2000Q is available under a separate datasheet and meets AEC-Q101 stress testing requirements for under-hood and infotainment systems operating from –40°C to +125°C ambient.
How does ZLLS2000TC perform at elevated temperatures?
At +100°C ambient, ZLLS2000TC maintains VF ≤ 450 mV at 2A and IR ≤ 0.6 mA at 30V, with derated continuous current of 1.3A to sustain TJ ≤ 150°C using standard FR-4 PCB layout with 1oz copper.
Is ZLLS2000TC compatible with lead-free reflow processes?
Yes-ZLLS2000TC features matte tin-plated copper leadframe and is rated for JEDEC J-STD-020 moisture sensitivity level 1, supporting peak reflow temperatures up to 260°C per IPC/JEDEC standard without delamination or solder joint reliability issues.
