Product details
Overview
BAS16LP-7B from Diodes Incorporated is a surface-mount silicon switching diode in an ultra-small X1-DFN1006-2 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It serves as a high-speed signal path switch or clamping element in low-power digital logic interfaces, ESD protection circuits, and level-shifting networks.
For engineers reviewing the BAS16LP-7B datasheet, BAS16LP-7B pinout, BAS16LP-7B application, or BAS16LP-7B equivalent, key selection criteria include its 2.0 pF junction capacitance at 0 V, sub-1.0 V forward voltage at 10 mA, 500 °C/W thermal resistance, and RoHS-compliant NiPdAu terminal finish - all critical for compact, high-frequency, thermally constrained PCB layouts.
Technical Context
This diode operates as a unidirectional, single-junction PN device optimized for fast transient response. Its 4.0 ns reverse recovery time (measured at IF = IR = 10 mA, Irr = 0.1 × IR, RL = 100 Ω) enables reliable operation in 10–50 MHz signal routing and pulse-clipping applications.
The X1-DFN1006-2 package features a 0.40 mm pitch, 1.00 mm × 0.60 mm footprint, and cathode-indicating top-side bar marking. Thermal performance is defined with FR-4 board mounting per AP02001 layout, yielding 250 mW power dissipation at 25°C ambient and linear derating to zero at 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRWM | 75 V - Maximum continuous reverse bias before significant leakage or breakdown in signal-switching paths |
| IF | 300 mA - Peak forward current capability supporting logic-level drive and moderate load switching |
| trr | 4.0 ns - Enables clean edge transitions in >20 MHz digital signal routing without ringing or overshoot |
| CT | 2.0 pF @ 0 V - Low junction capacitance preserves signal integrity in RF-coupled and high-speed data lines |
| VF | 0.855 V @ 10 mA - Low conduction loss minimizes voltage drop in level-shift and clamp configurations |
| RθJA | 500 °C/W - Requires careful thermal pad design on FR-4 for sustained 200 mW average dissipation |
| IR | 1.0 µA @ 75 V - Sufficient isolation for CMOS input protection and analog signal gating |

Applications
| USB Data Line Protection | Logic-Level Translation |
|---|---|
Use Scenario: Protecting USB 2.0 D+/D− lines from ESD transients and overvoltage coupling during hot-plug events. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed between data line and VCC/GND rails to shunt surge energy. Use Value: 2.0 pF capacitance avoids signal integrity degradation at 480 Mbps; 4.0 ns trr prevents latch-up during fast transients. | Use Scenario: Level shifting between 3.3 V microcontroller GPIO and 5 V peripheral interface. IC Role / Device Role / Timing Role: Passive open-drain translator using forward-biased diode drop to offset voltage thresholds. Use Value: 0.855 V VF at 10 mA provides predictable ~0.8 V offset; low leakage maintains high-impedance state when inactive. |
| RF Signal Routing Switch | Low-Power Sensor Interface Clamping |
Use Scenario: High-frequency antenna switch control in ISM-band (2.4 GHz) IoT transceivers. IC Role / Device Role / Timing Role: Series-connected switching diode enabling/disabling RF path based on DC bias polarity. Use Value: 2.0 pF CT minimizes insertion loss; 4.0 ns trr ensures minimal distortion of modulated carrier edges. | Use Scenario: Input protection for precision analog sensors (e.g., thermistors, bridge amplifiers) exposed to transient noise. IC Role / Device Role / Timing Role: Shunt clamp limiting input voltage swing to ±0.85 V beyond rail. Use Value: 1.0 µA leakage at 75 V preserves sensor bias accuracy; 250 mW PD handles short-duration surges without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Higher VRWM (30 V), lower VF (0.45 V @ 100 mA), larger SOD-523 package (1.2 × 0.8 mm) | Better for low-voltage, high-current switching; less suitable for 75 V signal isolation | Select when forward voltage minimization outweighs voltage rating and board space constraints |
| 1N4148W-7-F | Same VRWM (100 V), slower trr (4 ns typical but up to 8 ns), larger SOD-123 package (3.7 × 1.6 mm) | Proven reliability in legacy designs; unsuitable for dense, high-frequency layouts | Choose only for cost-sensitive, non-miniaturized, or legacy-replacement use cases |
Compared with NSR0230HT1G and 1N4148W-7-F, the BAS16LP-7B uniquely balances 75 V blocking, 4.0 ns speed, and 1.0 mm² footprint - making it optimal for space-constrained, medium-voltage, high-frequency signal routing where thermal and capacitive limits are critical.

FAQ
What is the cathode identification method for BAS16LP-7B?
The cathode is marked by a bar on the top surface of the X1-DFN1006-2 package. This marking aligns with the standard polarity convention used across Diodes Incorporated's DFN diodes and is visible under 10× magnification during visual inspection or automated optical recognition.
Can BAS16LP-7B be used in 5 V logic clamping applications?
Yes - with a 0.855 V forward voltage at 10 mA and 1.0 µA leakage at 75 V, it reliably clamps signals to within ~0.85 V above VCC or below GND. Its 2.0 pF capacitance avoids timing skew in 5 V TTL/CMOS signal paths operating up to 50 MHz.
Is BAS16LP-7B suitable for reflow soldering per JEDEC J-STD-020?
Yes - it is rated for Moisture Sensitivity Level 1 and qualified for standard Pb-free reflow profiles (peak 260°C). The NiPdAu terminal finish ensures robust wetting, and the X1-DFN1006-2 package withstands thermal cycling without solder joint cracking when mounted per AP02001 recommended pad layout.
How does BAS16LP-7B's thermal performance compare to SOT-23 diodes?
Its 500 °C/W RθJA is higher than typical SOT-23 diodes (~300–400 °C/W), due to smaller copper area in the DFN footprint. Effective thermal relief requires optimized PCB copper pour under the thermal pad and adherence to Diodes' AP02001 layout - not direct substitution without thermal validation.
