Product details
Overview
ZLLS410TC from Diodes Incorporated is a 10 V, 750 mA low-leakage Schottky diode in SOD323 package, featuring 1 µA reverse current at 10 V and 285–580 mV forward voltage across 10 mA–1 A loads; optimized for high-temperature DC-DC conversion and reverse blocking in compact power management circuits.
For engineers reviewing the ZLLS410TC datasheet, ZLLS410TC pinout, ZLLS410TC application, or ZLLS410TC equivalent, key selection criteria include its 1 µA IR at VR = 10 V, thermal rating to 150°C junction, SOD323 footprint compatibility, and low VF performance under pulsed and continuous high-current conditions.
Technical Context
This Schottky diode uses a planar silicon structure with low-barrier metal-semiconductor junction to achieve fast switching (trr = 3 ns) and minimal charge storage (Qrr = 210 pC), enabling efficient operation in high-frequency buck converters and synchronous rectification paths.
Its thermal design supports sustained operation up to 150°C junction temperature, with RθJA = 317–379 °C/W depending on PCB copper coverage, and is rated for 1.35 A peak forward current under 100 µs pulses-critical for transient load handling in portable and automotive power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 10 V - Maximum continuous blocking capability without breakdown; suitable for 5–9 V input rail protection and level-shifting interfaces. |
| Forward Current (IF) | 750 mA - Continuous DC current handling at TA = 25°C; supports compact DC-DC output stages without forced cooling. |
| Reverse Leakage (IR) | 1 µA at VR = 10 V - Enables ultra-low standby power loss in battery-backed systems and energy-sensitive IoT nodes. |
| Forward Voltage (VF) | 300 mV at IF = 100 mA - Reduces conduction loss by >40% vs. standard silicon diodes, improving efficiency in low-voltage converters. |
| Reverse Recovery (trr) | 3 ns - Minimizes switching loss and EMI in >1 MHz SMPS designs; eliminates need for snubbers in many layouts. |
| Capacitance (CD) | 37 pF at f = 1 MHz, VR = 10 V - Low junction capacitance preserves high-frequency signal integrity in RF bias and fast-switching applications. |
| Package | SOD323 - 2.4 mm × 1.35 mm surface-mount footprint with 0.0049 g mass; compatible with automated pick-and-place and reflow profiles per J-STD-020 Level 1. |
Pinout & Package
SOD323 package: 2-terminal surface-mount device with cathode marked by band; thermally rated to 150°C junction, molded green compound, UL 94V-0 flammability, matte tin terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry point during forward conduction | Connected to lower-potential node (e.g., switch node in buck converter); enables low-VF path when biased positive relative to cathode. |
| Cathode (C) | Current exit point during forward conduction; polarity reference | Marked with band; tied to higher-potential node (e.g., output rail); provides reverse-blocking isolation up to 10 V. |
Key Features
| Feature | Design Value |
|---|---|
| Extremely low leakage | IR ≤ 1 µA at VR = 10 V and TA = 25°C - preserves battery life in always-on sensor nodes and backup power paths. |
| High current density | 750 mA continuous in 2.4 mm × 1.35 mm footprint - eliminates need for paralleling diodes in space-constrained DC-DC modules. |
| Low forward voltage | VF = 300 mV @ 100 mA - reduces power loss by 0.3 W vs. 0.6 V diode at same current, critical for thermal budget in sealed enclosures. |
| Fast switching | trr = 3 ns, Qrr = 210 pC - enables clean turn-off in 2–5 MHz switching regulators without voltage spikes or shoot-through risk. |
| High-temperature operation | Junction rated to 150°C with RθJA ≤ 317 °C/W - sustains full current in automotive under-hood and industrial motor-control environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | 30 V VR, 200 mA IF, 100 nA IR @ 20 V - higher voltage rating but lower current and leakage | Better for 24 V industrial sensing; insufficient for 750 mA DC-DC outputs | Select only if VR > 10 V and IF < 300 mA are required; not drop-in for ZLLS410TC's power handling. |
| SBM130L | 30 V VR, 1.3 A IF, 5 µA IR @ 30 V - higher current and voltage, but 5× higher leakage at 10 V | Suitable for general-purpose 12 V rectification where leakage < 1 µA is not critical | Prefer when thermal margin is tight but leakage tolerance > 2 µA; avoid in battery-critical designs. |
Compared with RB521S-30T2R and SBM130L, ZLLS410TC uniquely balances 10 V blocking, 750 mA current, and sub-microamp leakage-making it optimal for thermally constrained, battery-sensitive 5–9 V power rails where both efficiency and standby integrity are mandatory.
