Product details
Overview
DLLFSD01LPH4-7B from Diodes Incorporated is an ultra-low leakage, fast-switching surface-mount Schottky diode in a 1.0 × 0.6 mm X2-DFN1006-2 package. It delivers 80 V peak repetitive reverse voltage, <1 pF capacitance at 0 V, 4.0 ns reverse recovery time, and only 5 nA reverse leakage at 5 V - enabling precision signal clamping and high-frequency rectification in space-constrained RF and sensor front-end circuits.
For engineers reviewing the DLLFSD01LPH4-7B datasheet, DLLFSD01LPH4-7B pinout, DLLFSD01LPH4-7B application, or DLLFSD01LPH4-7B equivalent, key selection criteria include ultra-low IR for battery-backed signal paths, sub-1pF CT for minimal RF loading, fast trr for >100 MHz switching, and thermal performance under 300 mA forward current in ultra-thin portable designs.
Technical Context
This Schottky diode uses a planar silicon structure optimized for low barrier height and minimized junction area to achieve nanoscale reverse leakage. Its 0.4 mm profile and NiPdAu-plated terminals support fine-pitch automated assembly on thin PCBs while maintaining robust solder joint integrity per MIL-STD-202.
The device operates across –65°C to +150°C with a 357°C/W junction-to-ambient thermal resistance on FR-4, and its power derating curve shows linear reduction from 350 mW at 25°C to zero at 150°C - critical for thermally dense IoT sensor nodes and wearable power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 80 V - supports DC blocking in 48 V industrial bus interfaces without avalanche stress |
| IR @ 5 V | 5 nA - enables microamp-level bias stability in photodiode transimpedance amplifiers |
| CT @ 0 V | 0.5–2.5 pF - ensures minimal signal distortion in 2.4 GHz Wi-Fi antenna switch paths |
| trr | 4.0 ns - allows clean edge preservation in 100+ MHz clock line clamping applications |
| IFM | 300 mA - sustains pulsed current in LED driver snubber networks without thermal runaway |
| RθJA | 357 °C/W - requires ≤150°C ambient for full-rated power on standard FR-4 with recommended pad layout |
Pinout & Package
Package: X2-DFN1006-2 (1.0 × 0.6 × 0.4 mm), leadless, cathode-bar marked on top surface; molded green compound, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Anode) | Anode connection | Exposed copper leadframe pad - primary current entry point; requires thermal pad connection for power dissipation |
| Terminal 2 (Cathode) | Cathode connection | Bar-marked side; NiPdAu finish ensures reliable reflow solderability and low contact resistance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IR | 5 nA @ VR = 5 V - preserves signal integrity in high-impedance analog monitoring paths |
| Sub-1pF capacitance | 0.5 pF typical @ 0 V - minimizes insertion loss in 5 GHz RF front-end matching networks |
| 4.0 ns trr | Measured at IF = IR = 10 mA, RL = 100 Ω - enables clean waveform clipping in digital logic level translation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-switching, ultra-low-leakage diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT54C-7-F | Higher IR (1 µA @ 5 V), larger 1.3 × 1.2 mm SOT-23 package, VF = 0.33 V @ 10 mA | Less suitable for nanoamp-bias circuits; better for higher-current (<200 mA) general-purpose clamping | Choose when lower forward drop outweighs leakage and size constraints |
| NSR0230HT1G | Lower VRWM (30 V), same X1-DFN0603-2 (0.6 × 0.3 mm) footprint, IR = 100 nA @ 5 V | Restricted to ≤3.3 V systems; insufficient for 24/48 V industrial signal conditioning | Choose only for sub-3 V battery-powered wearables where footprint is paramount |
Compared with BAT54C-7-F and NSR0230HT1G, DLLFSD01LPH4-7B uniquely balances 80 V rating, 5 nA leakage, and 1.0 × 0.6 mm size - making it the sole option for miniaturized 24–48 V sensor interfaces requiring both high-voltage tolerance and femtoamp-level signal fidelity.

FAQ
What is the maximum continuous forward current for DLLFSD01LPH4-7B?
The maximum continuous forward current (IFM) is 300 mA at TA = 25°C. Derating begins at 357°C/W above 25°C ambient, reaching zero allowable current at 150°C. This rating assumes use of the recommended FR-4 pad layout per AP02001 to ensure thermal compliance.
Does DLLFSD01LPH4-7B have a specified junction-to-case thermal resistance?
No, RθJC is not specified in the datasheet. Only RθJA = 357°C/W (on FR-4 with recommended pad layout) is provided. Thermal design must rely on this value and board-level thermal modeling, as no internal thermal interface data is published.
Is the cathode marking visible on the bottom or top surface?
The cathode is marked by a bar on the top surface of the device. The bottom view shows no marking; the top-view schematic in DS37663 Rev. 4–2 clearly indicates the bar adjacent to Terminal 2, confirming polarity orientation during automated optical inspection and placement.
Can DLLFSD01LPH4-7B be used in automotive applications?
While qualified for –65°C to +150°C operation, DLLFSD01LPH4-7B is not AEC-Q200 qualified and lacks automotive-specific reliability testing or PPAP documentation. It may be used in non-safety-critical infotainment or body-control auxiliary functions, but not in ADAS, powertrain, or safety systems without additional qualification.
