Product details
Overview
QSG0115UDJ-7 from Diodes Incorporated is a dual common-cathode Schottky barrier diode in SOT963 package, rated for 15 V peak reverse voltage, 100 mA average rectified current, and 0.4 V max forward voltage at 10 mA. It delivers ultra-low leakage (≤15 µA at 10 V), 5 ns max reverse recovery time, and is optimized for voltage clamping and fast switching in portable power rails.
For engineers reviewing the QSG0115UDJ-7 datasheet, QSG0115UDJ-7 pinout, QSG0115UDJ-7 application, or QSG0115UDJ-7 equivalent, key selection criteria include its dual common-cathode configuration, 2.93–8.0 pF junction capacitance at 1 MHz, thermal resistance of 347 °C/W on 100 mm² copper, and compliance with RoHS, halogen-free, and antimony-free "Green" standards.
Technical Context
This dual Schottky diode integrates two anode terminals sharing one cathode terminal in a single SOT963 package. Its low VF (0.11–0.4 V) and fast trr (1.49–5.0 ns) enable efficient clamping and steering in low-voltage DC paths below 15 V.
The device operates across –65°C to +150°C and exhibits temperature-dependent leakage: ≤0.25 µA at 5 V/25°C, rising to ≤100 µA at 5 V/150°C. Junction capacitance drops from ~8.0 pF at 1 V to ~1 pF near 10 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 15 V - Maximum non-repetitive reverse voltage before breakdown; sets clamping ceiling in 3.3 V/5 V rail protection |
| IO | 100 mA - Continuous DC current per diode; supports low-power signal path isolation and biasing |
| VF (max) | 0.4 V @ 10 mA - Low conduction loss enables >95% efficiency in 1.8–3.3 V logic-level clamping |
| IR (max) | 15 µA @ 10 V - Minimal leakage preserves battery life in always-on mobile standby circuits |
| trr | 5.0 ns - Enables clean edge handling in <100 MHz digital signal routing and ESD transient suppression |
| CT | 2.93–8.0 pF @ 1 MHz - Low capacitance avoids signal integrity degradation in high-speed GPIO lines |
| RθJA | 347 °C/W - Thermal performance validated on 100 mm² 2 oz copper; supports 260 mW dissipation in compact layouts |
Pinout & Package
Package: SOT963 - ultra-small surface-mount, 1.0 × 1.0 × 0.45 mm, 6-pin footprint with exposed thermal pad (not electrically connected). Molded green compound, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input node for first diode | Accepts forward-biased current into shared cathode; used for rail-to-rail clamping or OR-ing |
| Cathode (Pin 2) | Common output node | Shared cathode connection for both diodes; ties to reference potential (e.g., VCC or GND) |
| Anode 2 (Pin 3) | Input node for second diode | Independent anode path enabling dual-directional clamping or dual-rail protection |
| No Connect (Pins 4–6) | Thermal pad / mechanical anchor | Non-functional pins; serve as solderable thermal mass and mechanical stability anchors only |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-cathode topology | Enables compact dual-rail clamping (e.g., USB D+/D− or I²C SDA/SCL) without discrete part duplication |
| 0.4 V max VF @ 10 mA | Reduces forward drop by ≥30% vs. standard silicon diodes, critical for sub-3.3 V system margin |
| 5 ns max trr | Prevents shoot-through and ringing in high-frequency switching nodes up to 100 MHz |
| Halogen & antimony free | Meets IPC-1752A Class 3 requirements; <900 ppm Br/Cl, <1000 ppm Sb for eco-compliant manufacturing |
| SOT963 footprint | 0.003 g weight and 1.0 mm² area reduce PCB real estate by 60% vs. SOT23-6 equivalents |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2016LFG-7 | Single-channel, 20 V VRRM, 0.35 V VF @ 10 mA, SOT723 package | Lacks dual configuration; requires two devices for same functionality | Select when higher reverse voltage margin is needed and board space permits discrete placement |
| NSR20F30NXT5G | Dual common-anode, 30 V VRRM, 0.45 V VF @ 10 mA, SOD-923 package | Opposite polarity; requires circuit redesign for cathode-referenced clamping | Choose only if system design uses anode-referenced protection and 30 V tolerance is mandatory |
Compared with DMN2016LFG-7 and NSR20F30NXT5G, QSG0115UDJ-7 uniquely provides dual common-cathode topology in the smallest footprint (SOT963), lowest VF at 10 mA, and optimal 15 V rating for modern 3.3 V and lower logic systems-making it the most space- and efficiency-efficient choice for portable clamping.

FAQ
What is the thermal derating behavior of QSG0115UDJ-7 above +25°C?
Power dissipation decreases linearly with ambient temperature: PD = 360 mW − (TA − 25) × 0.33 mW/°C above 25°C, based on RθJA = 347 °C/W and 100 mm² copper. At +85°C, maximum safe continuous power drops to 156 mW.
Can QSG0115UDJ-7 be used in reverse-biased Zener-like clamping mode?
No - this is a Schottky diode, not a Zener. Its reverse breakdown is non-destructive only up to 15 V (VRRM). Intentional reverse conduction beyond that risks permanent damage; it must be operated within specified reverse voltage limits.
Is the SOT963 package's thermal pad electrically functional?
No - Pins 4–6 are mechanical anchors and thermal mass only. They are internally isolated from all semiconductor elements and must not be connected to any signal or power net; soldering them improves thermal performance but adds no electrical function.
How does junction capacitance vary with reverse bias in QSG0115UDJ-7?
CT decreases from 8.0 pF at 1 V reverse bias to ~2.93 pF at 10 V, per Figure 3 in DS36565. This voltage-dependent capacitance enables tunable filtering in RF bias networks and reduces capacitive loading on high-speed data lines at nominal operating bias.
