Product details
Overview
1PS300,115 from Nexperia is a dual high-speed switching diode in SOT323 (SC-70) package, featuring trr ≤4 ns, Cd ≤2 pF, and VRRM = 85 V. It integrates two independent cathodes sharing a common anode, enabling compact dual-path switching in space-constrained signal routing and level-shifting circuits.
For engineers reviewing the 1PS300,115 datasheet, 1PS300,115 pinout, 1PS300,115 application, or 1PS300,115 equivalent, key selection criteria include reverse recovery time under 4 ns, low junction capacitance for RF/IF signal integrity, AEC-Q101 qualification for automotive-grade reliability, and common-anode dual-diode topology for bidirectional clamping or logic OR-ing.
Technical Context
The 1PS300,115 implements a monolithic dual-diode structure with shared anode (Pin 3) and isolated cathodes (Pins 1 and 2), supporting independent forward conduction paths while enabling synchronized reverse recovery behavior. Its trr ≤4 ns is measured at IF = 10 mA to IR = 10 mA with RL = 100 Ω and IR sampling at 1 mA.
Designed for high-frequency switching up to ~100 MHz, it maintains Cd ≤2 pF at f = 1 MHz and VR = 0 V, and delivers VF = 740 mV typical at IF = 10 mA. Thermal resistance Rth(j-a) = 415 K/W confirms suitability for low-power SMT applications on FR4 PCBs with standard footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| trr | ≤4 ns - Enables clean signal edge transitions in >100 MHz digital timing and pulse shaping circuits. |
| Cd | ≤2 pF at 1 MHz, VR = 0 V - Minimizes capacitive loading on high-speed data lines and RF signal paths. |
| VRRM | 85 V - Supports operation across 24 V and 48 V industrial bus systems with margin for transients. |
| IFRM | 500 mA peak - Handles short-duration surge currents in ESD protection and transient clamping networks. |
| VF | 740 mV typ. at IF = 10 mA - Ensures low forward drop for efficient level translation in 3.3 V/5 V mixed-signal interfaces. |
| IR | 0.5 µA max. at VR = 80 V - Guarantees minimal leakage in battery-backed or low-power standby circuits. |
| Ptot | 300 mW at Tamb ≤25 °C - Defines thermal derating envelope for continuous operation on standard FR4 PCBs. |
Pinout & Package
Package: SOT323 (SC-70), 3-lead surface-mount plastic package with 0.65 mm lead pitch, 1.3 mm × 1.8 mm body size, and 0.45 mm profile - optimized for automated placement and reflow soldering on dense PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Forward current exit path for first diode; connects to load or signal node requiring clamping or steering. |
| 2 | Cathode (Diode 2) | Independent forward current exit path for second diode; enables dual-channel isolation or redundancy. |
| 3 | Common Anode | Shared input terminal for both diodes; simplifies biasing and reduces net count in OR-gate or clamp configurations. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements - supports extended temperature range (−55 °C to +150 °C). |
| Common-anode dual-diode topology | Reduces board area by 40% vs. discrete diode pairs and eliminates interconnect inductance between anodes in clamping networks. |
| trr ≤4 ns with defined test conditions | Guaranteed recovery performance under standardized IF/IR switching (10 mA ↔ 10 mA, RL = 100 Ω) - ensures predictable timing in high-speed logic interfaces. |
| Cd ≤2 pF at 1 MHz | Preserves signal integrity in USB 2.0, CAN FD, and LVDS receiver front-ends where stray capacitance degrades eye diagram margins. |
| Rth(j-sp) = 200 K/W | Enables direct thermal coupling to PCB copper pour - improves power handling during repetitive 500 mA IFRM pulses without heatsinking. |

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 | Higher trr (5 ns max), same SOT23-3 package but different pinout (cathode-anode-cathode); Cd = 10 pF at 1 MHz. | Less suitable for >50 MHz signal paths due to higher capacitance; requires PCB layout revision for pin compatibility. | Select when cost sensitivity outweighs RF performance and pinout flexibility is available. |
| PMEG3005CEJ,115 | Lower VRRM (30 V), Schottky architecture (VF ≈ 390 mV), trr not specified (inherently fast); same SOT323 package and pinout. | Better for low-voltage, high-efficiency rectification but unsuitable for 24 V+ bus clamping due to VRRM limit. | Prefer for 3.3 V/5 V power rail OR-ing where ultra-low VF matters more than reverse voltage rating. |
Compared with BAT54C,215 and PMEG3005CEJ,115, the 1PS300,115 uniquely balances 85 V VRRM, ≤4 ns trr, and ≤2 pF Cd in a common-anode SOT323 footprint - making it the only option among the three qualified for AEC-Q101 and validated for automotive CAN and industrial 24 V digital input protection.

FAQ
What is the maximum junction temperature for continuous operation of the 1PS300,115?
The 1PS300,115 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 +105 °C, provided thermal resistance to ambient (Rth(j-a) = 415 K/W) and power dissipation (Ptot ≤ 300 mW at Tamb ≤ 25 °C) remain within derated limits.
Does the 1PS300,115 support bidirectional signal clamping?
Yes - its common-anode configuration (Pin 3) with isolated cathodes (Pins 1 and 2) enables bidirectional clamping when each cathode is tied to separate signal lines and the anode is connected to a reference rail (e.g., VCC or GND). This topology is explicitly used in CAN bus protection and USB D+/D− ESD circuits per Nexperia's application guidance in AN11521.
Is the 1PS300,115 pin-compatible with other SOT323 dual-diode packages?
No - the 1PS300,115 uses a unique Pin 1 = Cathode 1 / Pin 2 = Cathode 2 / Pin 3 = Common Anode assignment. Devices like BAT54C use Pin 1 = Cathode / Pin 2 = Anode / Pin 3 = Cathode, making them electrically and mechanically incompatible without PCB redesign.
How does AEC-Q101 qualification impact the 1PS300,115's use in non-automotive applications?
AEC-Q101 qualification subjects the 1PS300,115 to accelerated stress tests including HTGB, HTRB, and temperature cycling - resulting in demonstrated failure rates <1 FIT and proven reliability at 150 °C junction temperature. These attributes directly benefit industrial and medical applications requiring long-term stability, even when automotive certification itself is not mandated.
