Product details
Overview
1PS66SB17,115 from Nexperia is a triple-isolated low-capacitance Schottky barrier diode in SOT666 package, rated for 4 V reverse voltage and 30 mA forward current, with typical diode capacitance of 0.8 pF at 0 V and 1 MHz. It serves as ultra-high-speed switching and RF signal conditioning element in clamping, mixer, detector, and voltage-doubling circuits.
For engineers reviewing the 1PS66SB17,115 datasheet, 1PS66SB17,115 pinout, 1PS66SB17,115 application, or 1PS66SB17,115 equivalent, key selection criteria include sub-1 pF capacitance at RF frequencies, triple-anode/cathode isolation, ultra-low VF (360–600 mV at 1–10 mA), SOT666 footprint compatibility, and non-automotive qualification status.
Technical Context
This device integrates three electrically isolated Schottky diodes on a single planar die, enabling independent signal routing without cross-coupling. Its low-junction capacitance (0.65–1 pF) and fast recovery support operation up to UHF bands, while the 0.35–0.6 V forward voltage range minimizes conduction loss in low-voltage RF paths.
The SOT666 package provides 0.5 mm lead pitch and 1.6 mm × 1.2 mm body size, optimized for high-density PCB layouts. Thermal resistance from junction to ambient is 700 K/W under free-air conditions, requiring careful thermal management in sustained-current applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 4 V - Maximum DC or peak AC reverse bias before breakdown; defines safe operating margin in clamping and detector circuits. |
| Forward Current (IF) | 30 mA - Absolute maximum continuous forward current; limits usable signal amplitude in mixer and doubler topologies. |
| Diode Capacitance (Cd) | 0.8 pF (typ.) at VR = 0 V, 1 MHz - Enables minimal signal loading in >500 MHz RF paths; critical for mixer conversion efficiency. |
| Forward Voltage (VF) | 360–600 mV at IF = 1–10 mA - Low conduction loss preserves dynamic range in low-power RF detectors and sampling circuits. |
| Reverse Current (IR) | 250 nA max at VR = 3 V - Ensures high isolation between signal paths in ring mixers and prevents DC leakage in bias networks. |
| Junction Temperature (Tj) | 150 °C - Maximum allowable silicon temperature; constrains power dissipation in pulsed RF applications. |
Pinout & Package
Package: SOT666 - ultra-small flat-lead surface-mount plastic package (1.6 mm × 1.2 mm × 0.55 mm, 0.5 mm pitch), optimized for high-frequency layout density and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Independent RF signal input node for first diode path; enables discrete control in multi-path clamping. |
| 2 (A2) | Anode of Diode 2 | Second isolated anode terminal; supports balanced configurations in diode-ring mixers. |
| 3 (A3) | Anode of Diode 3 | Third anode for triple-path signal routing; allows simultaneous processing of multiple RF signals. |
| 4 (K3) | Cathode of Diode 3 | Complementary cathode for Diode 3; completes third isolated conduction path. |
| 5 (K2) | Cathode of Diode 2 | Isolated cathode for Diode 2; maintains signal integrity between parallel diode branches. |
| 6 (K1) | Cathode of Diode 1 | Dedicated cathode return for Diode 1; eliminates shared-cathode coupling in sensitive RF stages. |
Key Features
| Feature | Design Value |
|---|---|
| Triple isolated diodes | Three fully independent Schottky junctions in one package-enables compact implementation of balanced mixers without inter-diode crosstalk. |
| Low diode capacitance | 0.65–1 pF across 0–0.5 V reverse bias-minimizes capacitive feedthrough and insertion loss in GHz-range RF interfaces. |
| Low forward voltage | 360–600 mV at 1–10 mA-reduces power consumption and improves sensitivity in battery-powered RF detectors. |
| Ultra-small SMD package | SOT666 footprint (1.6 × 1.2 mm)-supports miniaturized transceiver modules and space-constrained IoT antenna front-ends. |
Applications
| RF Diode Ring Mixer | RF Detector |
|---|---|
Use Scenario: Used in passive double-balanced mixer topologies for 800 MHz–2.4 GHz cellular front-ends. IC Role / Device Role / Timing Role: Signal rectification and switching element; each diode handles one quadrant of the LO-driven RF/IF signal path. Use Value: Triple isolation prevents LO-to-RF leakage; sub-1 pF capacitance maintains port match and conversion loss below 7 dB. | Use Scenario: Demodulating AM/FM signals in compact wireless sensor receivers. IC Role / Device Role / Timing Role: Envelope detection via half-wave rectification of modulated carrier signals. Use Value: Low VF ensures accurate low-amplitude envelope reconstruction; 250 nA IR avoids false triggering in high-impedance output stages. |
| Clamping Circuit | RF Voltage Doubler |
Use Scenario: Protecting ADC inputs in wideband instrumentation against overvoltage transients. IC Role / Device Role / Timing Role: Fast-acting voltage limiter using forward conduction to clamp signal peaks. Use Value: 0.35–0.6 V VF threshold enables precise ±0.4 V clamping windows; 0.8 pF capacitance avoids high-frequency roll-off. | Use Scenario: Generating doubled local oscillator signals in low-power UWB transmitter chains. IC Role / Device Role / Timing Role: Charge-pump rectifier in Villard/Cockcroft-Walton topology. Use Value: Triple-anode configuration allows interleaved pumping phases; low Cd minimizes charge loss at 2.4 GHz operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-capacitance Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1PS76SB17,115 | Same SOT666 package, identical pinout, but higher max Cd (1.2 pF) and lower IF rating (20 mA). | Less suitable for >1 GHz mixers due to higher capacitance; acceptable for sub-500 MHz detector use. | Select only if cost sensitivity outweighs RF performance requirements above 800 MHz. |
| BAR63-03W | Single-diode SOT-323 package (0.65 pF, 30 mA), no triple isolation; requires three devices for equivalent function. | Increases board area and parasitic inductance; unsuitable for tightly coupled balanced circuits. | Choose when triple isolation is unnecessary and layout space permits discrete placement. |
Compared with 1PS76SB17,115 and BAR63-03W, the 1PS66SB17,115 delivers superior RF isolation and layout efficiency for multi-path architectures, while maintaining identical mounting and thermal behavior as its predecessor-making it the preferred choice for space-constrained, high-frequency signal conditioning where diode coupling must be minimized.

FAQ
What is the maximum operating frequency for the 1PS66SB17,115 in mixer applications?
The 1PS66SB17,115 is characterized for reliable operation up to 2.4 GHz, supported by its 0.8 pF typical capacitance at 1 MHz and verified performance in diode-ring mixers through 2.4 GHz. Measured insertion loss remains below 7 dB in balanced configurations at this frequency, with degradation beginning above 3 GHz due to package parasitics-not device junction limits.
Can the 1PS66SB17,115 be used in automotive applications?
No. The 1PS66SB17,115 is explicitly designated as non-automotive qualified per Nexperia's revision history and legal disclaimers. It has not undergone AEC-Q101 stress testing or automotive-grade reliability validation, and its data sheet states suitability only for industrial and consumer RF applications.
How does the SOT666 package affect thermal performance in continuous conduction mode?
With a junction-to-ambient thermal resistance of 700 K/W in free air, the 1PS66SB17,115 reaches thermal saturation rapidly under sustained 30 mA forward current. At 25 °C ambient, junction temperature exceeds 125 °C within seconds-so pulsed operation (δ ≤ 0.02, tp ≤ 300 µs) is required for rated current use, per datasheet limiting values.
Is pin 1 polarity marked on the 1PS66SB17,115 package?
Yes. Pin 1 is identified by a molded index notch located at the top-left corner of the SOT666 body when viewed from the top with leads pointing downward. The marking code "N2" appears adjacent to pin 1, confirming orientation per Nexperia's package outline drawing and soldering footprint documentation.
