Product details
Overview
1PS79SB17,115 from Nexperia is a planar low capacitance Schottky barrier diode in SOD523 (SC-79) 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 ultra-low forward voltage (360–450 mV at 1 mA), AEC-Q101 qualified, and used in RF detector and high-speed clamping circuits.
For engineers reviewing the 1PS79SB17,115 datasheet, 1PS79SB17,115 pinout, 1PS79SB17,115 application, or 1PS79SB17,115 equivalent, key selection criteria include sub-1 pF capacitance at RF frequencies, <450 mV VF at 1 mA, AEC-Q101 qualification, and SC-79 footprint compatibility in space-constrained digital and RF signal paths.
Technical Context
This Schottky diode uses a planar silicon structure optimized for minimal junction capacitance and low series resistance. Its 0.8 pF capacitance at 0 V and 1 MHz enables operation up to UHF bands, while the 360–450 mV forward voltage at 1 mA supports efficient signal rectification in low-power RF detectors.
The device operates across –65 °C to +150 °C ambient temperature and is qualified per AEC-Q101 for automotive under-hood and infotainment applications. Thermal resistance from junction to ambient is 450 K/W in free air, consistent with its ultra-small SOD523 thermal mass and leadframe design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 4 V - Maximum blocking voltage before breakdown; defines safe operating range in clamping and RF mixer bias networks. |
| Forward Current (IF) | 30 mA - Continuous DC current rating; supports pulsed and steady-state operation in detector and switching nodes. |
| Diode Capacitance (Cd) | 0.8 pF (typ.) at VR = 0 V, f = 1 MHz - Enables >1 GHz small-signal response in RF detector and mixer applications. |
| Forward Voltage (VF) | 360–450 mV at IF = 1 mA - Low conduction loss improves sensitivity in weak-signal RF detection and low-voltage logic clamping. |
| Reverse Current (IR) | 250 nA max at VR = 3 V - Minimizes leakage-induced offset error in precision RF sampling and biasing circuits. |
| Junction Temp (Tj) | 150 °C - Supports sustained operation in automotive engine control and power amplifier bias stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | Higher Cd (1.2 pF typ.), same VR (4 V), VF = 450 mV @ 1 mA | Less suitable for >800 MHz detector use due to higher capacitance | Prefer when cost sensitivity outweighs RF bandwidth requirements |
| Vishay VS-2EDH01-M3/84A | Higher VR (30 V), larger SOD-123 package, Cd = 1.5 pF | Designed for general-purpose clamping, not RF-optimized | Select only if higher voltage margin and board space permit |
Compared with NSR0230HT1G and VS-2EDH01-M3/84A, the 1PS79SB17,115 provides the lowest capacitance and smallest footprint-critical for GHz-range RF signal chains-while maintaining AEC-Q101 compliance for automotive-grade reliability in compact layouts.

FAQ
Is the 1PS79SB17,115 suitable for 2.4 GHz Wi-Fi receiver front-ends?
Yes. With 0.8 pF typical capacitance at 1 MHz and verified low parasitic behavior up to 3 GHz in Nexperia's characterization, it functions effectively as an RF detector or limiter in 2.4 GHz Wi-Fi receivers-provided layout minimizes pad inductance and ground return path length.
What is the meaning of the 'T2' marking on the device body?
The 'T2' marking is the manufacturer's traceable code for the 1PS79SB17,115 in SOD523 packaging, per Table 4 of the datasheet. It identifies the specific wafer lot and assembly batch, enabling full traceability for automotive and industrial quality audits.
Does this diode require derating at elevated ambient temperatures?
Yes. At Tamb = 85 °C, the maximum continuous forward current must be reduced to ~22 mA per Fig. 1's VF vs. IF curves and thermal limits. The 450 K/W Rth(j-a) implies ~100 mW total dissipation limit at 85 °C ambient before reaching 150 °C junction temperature.
Can the 1PS79SB17,115 replace BAT54S in existing designs?
No-BAT54S is a dual-series Schottky in SOT-23. While electrically similar per channel, 1PS79SB17,115 is single-diode in SOD523, differing in pin count, package size, and thermal performance. Direct replacement requires PCB redesign and validation of RF matching and thermal margins.
