Product details
Overview
1PS66SB82 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 diode capacitance at 0 V and 1 MHz-enabling RF detector and ultra-high-speed clamping applications.
For engineers reviewing the 1PS66SB82 datasheet, 1PS66SB82 pinout, 1PS66SB82 application, or 1PS66SB82 equivalent, key selection criteria include low-junction-capacitance performance, triple-diode isolation integrity, SOT666 thermal resistance (700 K/W), and compatibility with reflow-only soldering per JEDEC standards.
Technical Context
This triple-diode configuration provides three electrically isolated Schottky junctions in a single compact SMT package, eliminating cross-talk between signal paths in RF mixer and clamping circuits. Each diode exhibits sub-340 mV forward voltage at 1 mA and maintains ≤0.2 μA reverse leakage at 1 V.
The device operates across −65 °C to +125 °C ambient, with junction temperature limited to 125 °C. Its 1 pF capacitance and 12 Ω differential resistance at 5 mA/1 kHz support high-frequency signal integrity in detector and doubler topologies up to UHF bands.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 15 V continuous reverse voltage - defines maximum RF signal swing before breakdown in detector/doubler use |
| IF | 30 mA continuous forward current - supports sustained switching in digital clamping without thermal derating |
| Cd | 1 pF at VR = 0 V, f = 1 MHz - enables >500 MHz small-signal operation in ring mixers and RF detectors |
| VF | 700 mV max at IF = 30 mA - ensures low power loss and minimal voltage drop in high-speed logic interface clamping |
| IR | 0.2 μA max at VR = 1 V - guarantees negligible leakage-induced offset in precision RF detection |
| Rth(j-a) | 700 K/W in free air - requires careful PCB copper area design for thermal management in sustained 30 mA operation |
Pinout & Package
SOT666 is a 6-lead plastic surface-mounted package measuring 1.7 × 1.3 × 0.6 mm (L × W × H), with gull-wing leads and pin 1 index marked by notch or bevel. Standard mounting uses reflow only per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Independent anode terminal for first Schottky junction; no internal connection to other diodes |
| 2 | Anode (Diode 2) | Independent anode terminal for second Schottky junction; fully isolated from pins 1 and 3 |
| 3 | Anode (Diode 3) | Independent anode terminal for third Schottky junction; electrically isolated per datasheet pinning table |
| 4 | Cathode (Diode 3) | Dedicated cathode for Diode 3; forms complete isolated junction with pin 3 |
| 5 | Cathode (Diode 2) | Dedicated cathode for Diode 2; forms complete isolated junction with pin 2 |
| 6 | Cathode (Diode 1) | Dedicated cathode for Diode 1; forms complete isolated junction with pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Triple isolated Schottky junctions | Three independent diodes in one SOT666 footprint-reduces board space vs. discrete SOD-323 solutions by >60% |
| 1 pF diode capacitance | Enables clean RF signal coupling in 900 MHz–2.4 GHz detector and mixer stages without parasitic roll-off |
| 340 mV VF at 1 mA | Allows reliable turn-on with weak drive signals in low-power logic-level clamping and bias networks |
| Reflow-only soldering compliance | Eliminates risk of thermal damage during assembly; aligns with IPC-A-610 Class 2/3 process requirements |
Applications
| Ultra-High-Speed Digital Clamping | RF Diode Ring Mixer |
|---|---|
Use Scenario: Protecting FPGA I/O pins from overshoot/undershoot during hot-plug or level-shifting events. IC Role / Device Role / Timing Role: Fast-turn-on clamping diode limiting transient excursions to <0.7 V above VCC or below GND. Use Value: Sub-340 mV VF ensures clamping activates before CMOS input damage thresholds are exceeded. | Use Scenario: Balanced frequency conversion in 2.4 GHz ISM-band transceivers. IC Role / Device Role / Timing Role: Four-quadrant switching element in passive ring mixer core. Use Value: 1 pF Cd minimizes insertion loss and port-to-port coupling at RF frequencies. |
| RF Voltage Doubler | RF Signal Detector |
Use Scenario: Generating local oscillator harmonics for low-phase-noise upconversion in sensor nodes. IC Role / Device Role / Timing Role: Nonlinear rectifying element converting fundamental RF to second harmonic. Use Value: Low VF and high-speed recovery enable efficient doubling with <1 dB conversion loss at 915 MHz. | Use Scenario: Received signal strength indication (RSSI) in Bluetooth LE receivers. IC Role / Device Role / Timing Role: Envelope detector converting modulated RF to baseband DC voltage. Use Value: 0.2 μA IR at 1 V ensures stable DC output under weak-signal conditions (<−40 dBm). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-Schottky-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1PS88SB82 | SOT363 (SC-88) package; Rth(j-a) = 416 K/W; identical electrical specs | Better thermal performance but larger footprint (2.2 × 1.8 mm vs. 1.7 × 1.3 mm) | Select when board layout allows larger package and thermal dissipation is critical |
| RB050M-40 | Single Schottky diode in SOD-123; VF = 450 mV @ 30 mA; Cd = 30 pF | Not functionally equivalent-requires three devices and routing for triple isolation | Use only if triple-isolation is not required and board area is unconstrained |
Compared with 1PS88SB82 and RB050M-40, the 1PS66SB82 uniquely delivers triple isolation, 1 pF capacitance, and minimal 1.7 × 1.3 mm footprint-making it optimal for space-constrained RF front-ends where thermal budget permits 700 K/W junction-to-ambient resistance.

FAQ
What is the maximum operating temperature for 1PS66SB82?
The 1PS66SB82 has a maximum junction temperature of 125 °C and an ambient operating range of −65 °C to +125 °C. Thermal resistance is 700 K/W in free air, so PCB copper area and airflow must be designed to keep Tj ≤125 °C under 30 mA continuous load.
Is 1PS66SB82 suitable for reflow soldering only?
Yes-Nexperia specifies reflow soldering as the only recommended method. The SOT666 package is not qualified for wave or hand soldering due to thermal stress risks. Reflow profile must comply with JEDEC J-STD-020, peak temperature ≤260 °C.
How does the triple-isolated structure benefit RF mixer designs?
The three fully isolated Schottky junctions allow independent biasing and signal routing for balanced LO, RF, and IF ports in ring mixers. No shared cathodes or anodes prevent intermodulation distortion caused by common-node impedance coupling.
What marking code identifies 1PS66SB82 on the package?
The 1PS66SB82 is marked with the code "N5" on the top surface of the SOT666 package. This marking is visible under 20× magnification and conforms to Nexperia's standard SMD marking specification for SOT666 devices.
