Product details
Overview
1PS66SB82115 from Nexperia is a triple isolated Schottky barrier diode in SOT666 package, rated for 15 V reverse voltage and 30 mA forward current, with ultra-low 1 pF capacitance at 0 V and 1 MHz-enabling RF detector, diode ring mixer, and ultra-high-speed clamping applications.
For engineers reviewing the 1PS66SB82115 datasheet, 1PS66SB82115 pinout, 1PS66SB82115 application, or 1PS66SB82115 equivalent, this page delivers verified electrical specs, terminal mapping, thermal resistance (700 K/W), forward voltage (700 mV @ 30 mA), and real-world use cases in RF and digital signal conditioning circuits.
Technical Context
This device integrates three electrically isolated Schottky diodes in a single compact SOT666 package, optimized for high-frequency operation via low junction capacitance (1 pF) and low forward voltage (340 mV @ 1 mA). Its epitaxial construction ensures stable performance up to 125 °C junction temperature.
The triple-diode configuration supports independent anode/cathode routing per diode-pin 1–3 are anodes, pins 4–6 are cathodes-with no shared terminals. Thermal resistance of 700 K/W (junction-to-ambient, free air) reflects its suitability for low-power RF front-end and logic-level clamping where self-heating must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 15 V - supports signal clamping and RF detection in 12 V systems without breakdown risk |
| Forward Current (IF) | 30 mA continuous - sufficient for low-power logic interface and detector biasing |
| Diode Capacitance (Cd) | 1 pF @ 0 V, 1 MHz - enables >1 GHz small-signal RF operation with minimal loading |
| Forward Voltage (VF) | 700 mV @ 30 mA - reduces power loss and improves efficiency in high-speed switching paths |
| Differential Resistance (rdif) | 12 Ω @ 5 mA - ensures low insertion loss in RF mixer and detector signal paths |
| Junction Temperature (Tj) | 125 °C max - allows reliable operation in industrial ambient environments |
Pinout & Package
SOT666 plastic surface-mounted package (6 leads), dimensions: 1.7 × 1.3 × 0.5 mm (L × W × H), with standard reflow soldering compatibility only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Independent input node for first Schottky diode; routed separately for discrete clamping or mixing functions |
| 2 | Anode (Diode 2) | Independent input node for second Schottky diode; enables dual-path RF signal processing |
| 3 | Anode (Diode 3) | Independent input node for third Schottky diode; supports triple-function circuits like balanced mixers |
| 4 | Cathode (Diode 3) | Return path for Diode 3; isolated from other cathodes to prevent cross-coupling |
| 5 | Cathode (Diode 2) | Return path for Diode 2; maintains signal integrity in differential or multi-channel topologies |
| 6 | Cathode (Diode 1) | Return path for Diode 1; enables independent biasing and termination per diode |
Key Features
| Feature | Design Value |
|---|---|
| Triple isolated Schottky diodes | Enables independent signal routing across three channels without internal coupling-critical for balanced RF mixers |
| 1 pF diode capacitance | Minimizes capacitive loading on high-frequency traces, preserving bandwidth in >500 MHz detector circuits |
| 700 mV VF @ 30 mA | Reduces forward conduction loss in low-voltage clamping, improving signal fidelity in 3.3 V logic interfaces |
| SOT666 package | 0.5 mm height and 1.7 mm length enable dense RF layout while maintaining thermal isolation between diodes |
Applications
| RF Detector | Diode Ring Mixer |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1PS88SB82 | SOT363 (SC-88) package; identical electrical specs (15 V, 30 mA, 1 pF), but higher thermal resistance (416 K/W vs. 700 K/W) | Better suited for space-constrained layouts where footprint size matters more than thermal dissipation | Select 1PS88SB82 when board area is critical and ambient temperature remains below 85 °C |
| RB050M-30 | Single Schottky diode in SOD-523; 30 V VR, 100 mA IF, Cd ≈ 1.2 pF - not triple-isolated, different pin count and package | Applicable only for single-diode roles; requires three separate placements to replicate 1PS66SB82115 functionality | Choose RB050M-30 only when triple integration is unnecessary and higher current headroom is required |
Compared with 1PS88SB82 and RB050M-30, the 1PS66SB82115 uniquely delivers triple isolation in the smallest possible height (0.5 mm) while maintaining 15 V rating and 1 pF capacitance-making it optimal for stacked RF modules and miniaturized detector assemblies where vertical clearance and channel independence are design constraints.

FAQ
What is the maximum reverse voltage rating for the 1PS66SB82115?
The 1PS66SB82115 has a continuous reverse voltage (VR) rating of 15 V, as specified in the Absolute Maximum Ratings table. This value is confirmed across all operating temperatures up to 125 °C junction temperature and defines the upper limit for safe non-breakdown operation in clamping or detector configurations.
How many diodes are integrated into the 1PS66SB82115 and how are they configured?
The 1PS66SB82115 integrates three electrically isolated Schottky diodes in a single SOT666 package. Pins 1–3 serve as individual anodes, and pins 4–6 serve as corresponding cathodes-no internal connection exists between diodes, enabling fully independent signal paths.
What is the typical diode capacitance of the 1PS66SB82115 and under what conditions is it measured?
The 1PS66SB82115 exhibits a typical diode capacitance (Cd) of 1 pF, measured at 0 V reverse bias and 1 MHz frequency per Figure 4 in the official Nexperia datasheet. This value is consistent across production lots and critical for RF impedance matching and bandwidth preservation.
Can the 1PS66SB82115 be used in reflow soldering processes?
Yes-the 1PS66SB82115 is qualified for reflow soldering only, as explicitly stated in Section 6 of the Nexperia datasheet. Wave or hand soldering is not recommended due to thermal stress risks, and standard SOT666 reflow profiles must be followed to ensure reliability.
What marking code identifies the 1PS66SB82115 on the physical package?
The 1PS66SB82115 is marked with the code "N5" on its top surface, as documented in Table 5 of the Nexperia datasheet. This laser-marked identifier is standardized across all production units and corresponds exclusively to the 1PS66SB82 variant in SOT666 packaging.
