Product details
Overview
1PS76SB17,115 from Nexperia is a planar low capacitance Schottky barrier diode in SOD323 (SC-76) 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 delivers 360–450 mV forward voltage at 1 mA and is AEC-Q101 qualified for automotive-grade reliability in RF detector and ultra-high-speed clamping circuits.
For engineers reviewing the 1PS76SB17,115 datasheet, 1PS76SB17,115 pinout, 1PS76SB17,115 application, or 1PS76SB17,115 equivalent, key selection criteria include sub-1 pF capacitance at zero bias, <450 mV VF at 1 mA, AEC-Q101 qualification, SOD323 footprint compatibility, and cathode-marked anode-cathode polarity for RF mixer and high-speed digital clamping layouts.
Technical Context
This Schottky diode employs a planar silicon structure optimized for minimal junction capacitance and low forward conduction loss. Its 0.8 pF capacitance at VR = 0 V / f = 1 MHz and 0.65 pF at VR = 0.5 V enable stable impedance matching in RF detector and ring mixer topologies up to UHF frequencies.
The device operates within −65 °C to +150 °C ambient range and supports pulsed forward currents up to 30 mA with thermal resistance Rth(j-a) = 450 K/W in free air. Reverse leakage remains ≤250 nA at 3 V and 25 °C, ensuring low DC offset in precision RF voltage doubling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 4 V - Maximum blocking voltage before breakdown; defines safe operating limit in clamping and RF detector bias networks. |
| Forward Current (IF) | 30 mA - Continuous DC or pulsed forward current rating; sets maximum signal-handling capacity in switching paths. |
| Diode Capacitance (Cd) | 0.8 pF (typ.) at VR = 0 V, 1 MHz - Enables minimal signal distortion and high-frequency response in RF mixer and detector stages. |
| Forward Voltage (VF) | 360–450 mV at IF = 1 mA - Low conduction loss improves efficiency and reduces self-heating in low-power RF signal routing. |
| Reverse Current (IR) | ≤250 nA at VR = 3 V, 25 °C - Ensures negligible leakage-induced DC drift in precision RF detection and sampling circuits. |
| Junction Temperature (Tj) | 150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive environments. |
| AEC-Q101 Qualified | Yes - Validated per Automotive Electronics Council stress test standard for discrete semiconductors; suitable for automotive infotainment and ADAS sensor interfaces. |
Pinout & Package
Encapsulated in a SOD323 (SC-76) surface-mount plastic package measuring 1.7 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch, the 1PS76SB17,115 features a two-terminal configuration where the cathode is marked by a bar on the package body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to circuit ground or lower-potential node; marking bar identifies this terminal for correct orientation in RF detector and clamping layouts. |
| 2 | Anode (A) | Connected to signal source or higher-potential node; forms forward-biased path during positive half-cycle in voltage doubler and mixer applications. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky barrier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-40T1G | 40 V VR, 200 mA IF, 1.5 pF Cd at 0 V - Higher voltage rating but 87.5% higher capacitance. | Preferred in 5 V+ clamping and general-purpose rectification; unsuitable for >1 GHz RF detectors due to capacitance. | Select when system requires higher reverse margin and lower cost; avoid where sub-1 pF is mandatory. |
| NSR0230HT1G | 30 V VR, 200 mA IF, 1.2 pF Cd at 0 V - Higher IF rating but 50% greater capacitance than 1PS76SB17,115. | Better suited for USB data line protection and 3.3 V logic clamping; marginal for UHF mixer use. | Choose for higher current handling in industrial I/O protection; not recommended for RF detector front-ends. |
Compared with RB521S-40T1G and NSR0230HT1G, the 1PS76SB17,115 uniquely balances sub-1 pF capacitance, AEC-Q101 qualification, and SOD323 footprint-making it the only option among the three validated for automotive-grade RF detector and mixer designs requiring <0.9 pF and ≤450 mV VF at 1 mA.

FAQ
What is the maximum reverse voltage rating for the 1PS76SB17,115?
The absolute maximum reverse voltage (VR) for the 1PS76SB17,115 is 4 V, as defined in IEC 60134 Absolute Maximum Ratings. Operation beyond this value risks irreversible junction breakdown. This rating makes it suitable for low-voltage RF and digital clamping, but not for 5 V or higher bus protection without derating.
Is the 1PS76SB17,115 suitable for automotive applications?
Yes-the 1PS76SB17,115 is fully qualified to AEC-Q101 standards for discrete semiconductors, including temperature cycling, high-temperature reverse bias, and mechanical shock testing. It is approved for use in automotive infotainment, ADAS sensor interfaces, and body control modules where space and RF performance are critical.
How is cathode identification implemented on the SOD323 package?
The cathode (pin 1) is identified by a visible marking bar on the top surface of the SOD323 package. This bar aligns with the cathode symbol 'K' in the device's simplified outline and must be oriented toward the lower-potential node in circuit layout to ensure correct forward biasing in RF detector and clamping configurations.
What is the thermal resistance from junction to ambient for this diode?
The thermal resistance from junction to ambient (Rth(j-a)) is 450 K/W under free-air conditions, per Nexperia's SOD323 standard mounting guidelines. This value assumes no PCB copper pour or heatsinking; actual thermal performance improves significantly with 20 mm² of 1 oz copper connected to both terminals.
