Product details
Overview
1PS301,115 from Nexperia is a dual high-speed switching diode in SOT323 (SC-70) package, featuring trr ≤ 4 ns, Cd ≤ 1.5 pF, and VRRM ≤ 85 V. It integrates two anodes sharing a common cathode for compact signal routing in space-constrained high-frequency circuits such as USB 2.0 data line protection and RF front-end switching.
For engineers reviewing the 1PS301,115 datasheet, 1PS301,115 pinout, 1PS301,115 application, or 1PS301,115 equivalent, key selection criteria include reverse recovery time under 4 ns, low junction capacitance at 1.5 pF, AEC-Q101 qualification for automotive use, and dual-diode topology with shared cathode configuration.
Technical Context
The 1PS301,115 implements a monolithic dual-diode structure with isolated P-N junctions sharing a single cathode terminal (Pin 3), enabling independent forward conduction paths from Pin 1 and Pin 2 while minimizing parasitic inductance in high-speed switching nodes. Its design targets fast transient response in bidirectional signal clamping and polarity-selective routing.
Thermal resistance Rth(j-a) of 415 K/W and Rth(j-sp) of 200 K/W reflect optimized thermal path design for FR4 PCB mounting, supporting continuous operation up to 150 °C junction temperature. The device operates within ambient temperatures from −55 °C to +150 °C, validated per IEC 60134 absolute maximum rating system.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| trr | ≤ 4 ns - Enables sub-10 ns switching transitions in 50 MHz+ digital signal paths. |
| Cd | ≤ 1.5 pF at 1 MHz, VR = 0 V - Minimizes signal loading on high-impedance RF or high-speed data lines. |
| VRRM | 85 V - Supports transient suppression in 24 V automotive power domains and industrial control I/O. |
| IFRM | 500 mA peak - Handles surge currents during hot-swap or ESD event recovery without degradation. |
| VF @ 10 mA | 740 mV typical - Ensures low forward drop for minimal voltage loss in bias and level-shifting circuits. |
| IR @ 80 V | 0.5 µA max - Guarantees leakage below 1 µA in battery-backed or ultra-low-power standby modes. |
| Ptot | 300 mW at Tamb ≤ 25 °C - Defines thermal derating envelope for sustained operation on standard FR4 PCBs. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT54C,215 | trr = 5 ns (typ), Cd = 10 pF (typ), VRRM = 30 V, non-AEC-Q101 | Limited to 30 V systems; higher capacitance degrades >100 MHz performance | Select when cost sensitivity outweighs speed/capacitance requirements in non-automotive consumer designs. |
| NSR0230HT1G | trr = 3 ns (typ), Cd = 1.2 pF (typ), VRRM = 30 V, AEC-Q101 qualified | Lower VRRM restricts use to 3.3 V/5 V logic domains; lacks dual-anode topology | Prefer for ultra-high-speed <1 ns edge applications where single-diode isolation is acceptable and voltage range permits. |
Compared with BAT54C,215 and NSR0230HT1G, the 1PS301,115 uniquely balances 85 V VRRM, 4 ns trr, 1.5 pF Cd, and AEC-Q101 compliance in a dual-anode/common-cathode SOT323 package-making it the only option meeting all four criteria simultaneously for automotive and industrial high-voltage, high-speed switching.

FAQ
What is the maximum junction temperature for continuous operation of the 1PS301,115?
The 1PS301,115 has a maximum junction temperature (Tj) rating of 150 °C, verified per IEC 60134 limiting values. This allows uninterrupted operation in under-hood automotive environments and industrial enclosures where ambient temperatures reach +125 °C, provided thermal resistance to ambient (Rth(j-a) = 415 K/W) and power dissipation remain within derated limits.
Is the 1PS301,115 suitable for bidirectional signal clamping applications?
Yes-the 1PS301,115 supports bidirectional clamping via its dual-anode/common-cathode configuration: connecting Pin 1 to positive rail and Pin 2 to negative rail (or vice versa) enables symmetrical voltage limiting across differential signal pairs such as USB D+/D− or CAN_H/CAN_L, with matched trr and Cd characteristics ensuring balanced transient response.
How does the 1PS301,115 differ from standard Schottky diodes in high-speed switching roles?
Unlike Schottky diodes, the 1PS301,115 uses silicon P-N junction technology to achieve lower reverse leakage (0.5 µA at 80 V vs. typical Schottky µA–mA range) and higher VRRM (85 V vs. typically ≤40 V), while maintaining competitive trr (≤4 ns) and Cd (≤1.5 pF). This makes it preferable where low IR and high reverse voltage tolerance are critical, such as in 24 V industrial I/O protection.
Can the 1PS301,115 be used in place of two separate SOT23 diodes?
Yes-its SOT323 footprint occupies ~40% less board area than two discrete SOT23 diodes, and the shared cathode eliminates one PCB trace. However, substitution requires verifying that circuit topology accommodates the common-cathode constraint (e.g., both anodes must connect to different signal sources feeding the same return node), unlike independent dual-diode configurations.
