Product details
Overview
1PS184,135 from Nexperia is a high-speed double diode with common cathode configuration in SC59 SMD package, featuring 4 ns reverse recovery time, 85 V repetitive peak reverse voltage, and 500 mA peak forward current. It serves as a compact dual switching element in space-constrained surface-mounted power management and signal routing circuits.
For engineers reviewing the 1PS184,135 datasheet, 1PS184,135 pinout, 1PS184,135 application, or 1PS184,135 equivalent, key selection criteria include reverse recovery speed, dual-diode thermal derating behavior, common-cathode topology compatibility, and FR4-board thermal resistance (500 K/W).
Technical Context
The 1PS184,135 integrates two planar-technology silicon switching diodes sharing a single cathode terminal, enabling synchronized high-speed switching without cross-conduction risk. Its SC59 package supports automated placement while maintaining low junction-to-ambient thermal resistance (500 K/W) on standard FR4 PCBs.
Electrical operation is characterized by sub-nanosecond-level charge storage control: trr ≤ 4 ns at IF = 10 mA → IR = 10 mA with 100 Ω load, VF ≤ 1.2 V at IF = 100 mA, and Cd ≤ 1.5 pF at VR = 0 V, f = 1 MHz - all specified per diode under Tj = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | ≤ 4 ns - enables >200 MHz switching in clamping and sampling circuits |
| Repetitive Peak Reverse Voltage (VRRM) | 85 V - supports 24 V/48 V industrial bus transient suppression |
| Peak Forward Current (IFRM) | 500 mA - allows pulsed operation in dual-path DC-DC feedback networks |
| Diode Capacitance (Cd) | ≤ 1.5 pF at 0 V - minimizes signal distortion in RF detector and mixer bias paths |
| Junction-to-Ambient Thermal Resistance | 500 K/W on FR4 - requires derating to 125 mA when both diodes conduct continuously at Tamb = 70 °C |
| Forward Voltage (VF) | ≤ 1.2 V at 100 mA - ensures low conduction loss in low-voltage logic-level clamping |
Pinout & Package
Package: SC59 - 3-pin small-outline plastic SMD package (3.1 × 1.7 × 1.3 mm), marked "B3T", optimized for high-density automated assembly and thermal performance on FR4 boards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Independent input path for first high-speed switching channel |
| 2 | Anode of Diode 2 (A2) | Independent input path for second high-speed switching channel |
| 3 | Common Cathode (K) | Shared output node enabling OR-ing, level shifting, or dual-input clamp topologies |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed Switching | trr ≤ 4 ns ensures minimal tail current in fast edge-detection and pulse shaping |
| Common-Cathode Dual Diode | Reduces board area vs. discrete diodes and eliminates cathode wiring mismatch in matched-path designs |
| Low Junction Capacitance | Cd ≤ 1.5 pF enables use in 1–100 MHz RF signal path conditioning without added tuning |
| FR4-Compatible Thermal Design | Rth j-a = 500 K/W allows direct thermal modeling for ambient temperatures up to 70 °C with dual-diode loading |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT54C,215 | Higher VF (1.25 V @ 100 mA), same SC59 package, trr = 5 ns | Slightly higher conduction loss; suitable where 1 ns trr margin is noncritical | Preferred when sourcing consistency with existing BAT54-series BOMs |
| PMEG3005CEJ,115 | Lower VRRM (30 V), Schottky architecture, trr not specified (inherently fast) | Not suitable for >30 V reverse conditions; better for low-VF, low-noise analog biasing | Select only for sub-24 V systems requiring <0.3 V forward drop |
Compared with BAT54C,215 and PMEG3005CEJ,115, the 1PS184,135 uniquely balances 85 V reverse rating, 4 ns trr, and SC59 footprint - making it optimal for industrial 24/48 V signal clamping where both speed and voltage margin are required.

FAQ
What is the maximum continuous forward current rating for each diode in the 1PS184,135 when operating at 25 °C ambient?
At Tamb = 25 °C, the 1PS184,135 supports 215 mA per diode when only one diode is conducting continuously. When both diodes conduct simultaneously, the rating drops to 125 mA due to shared thermal path and total power dissipation limit of 250 mW. This derating is defined in the Limiting Values table and verified under FR4 board mounting conditions.
Does the 1PS184,135 have a documented reverse recovery time specification, and under what test conditions?
Yes, the 1PS184,135 has a guaranteed maximum reverse recovery time (trr) of 4 ns. This value is measured per diode when switched from IF = 10 mA to IR = 10 mA, with RL = 100 Ω, and detection at IR = 1 mA - as defined in Figure 6 of the official Nexperia datasheet. The test uses a 50 Ω source and sampling oscilloscope setup.
What is the marking code for the 1PS184,135, and how is it physically arranged on the SC59 package?
The 1PS184,135 is marked "B3T" on the top surface of its SC59 package. The marking appears adjacent to pin 1 (anode of diode 1), oriented horizontally with the "B" closest to the package notch or beveled corner. This matches the pin 1 identification shown in Figure 1 of the Nexperia datasheet and is consistent across all 1PS184,135 units supplied in tape-and-reel format.
Can the 1PS184,135 be used in place of a single discrete diode, and what design considerations apply?
Yes, the 1PS184,135 can replace a single diode by connecting either pin 1 or pin 2 as the anode and pin 3 as the cathode, leaving the unused anode unconnected. Designers must ensure the floating anode is not exposed to unintended voltage transients, and verify that thermal limits remain within spec - since the unused diode still contributes to junction heating under high-power operation of the active diode.
What is the diode capacitance of the 1PS184,135, and at what bias condition is it specified?
The 1PS184,135 has a maximum diode capacitance (Cd) of 1.5 pF, measured at f = 1 MHz with VR = 0 V and Tj = 25 °C - as stated in the Electrical Characteristics table. This low capacitance is confirmed across the full reverse voltage range (0–8 V) in Figure 5 of the datasheet and makes the 1PS184,135 suitable for high-frequency signal path applications.
