Product details
Overview
1SS361LPH4-7B from Diodes Incorporated is a surface-mount ultra-fast switching diode in X2-DFN1006-2 package, rated for 80 V peak repetitive reverse voltage, 300 mA forward current, and featuring 2.0 ns typical reverse recovery time, 0.63 pF capacitance at 0 V, and 0.715 V forward voltage at 10 mA - used in high-frequency signal routing and RF detector circuits.
For engineers reviewing the 1SS361LPH4-7B datasheet, 1SS361LPH4-7B pinout, 1SS361LPH4-7B application, or 1SS361LPH4-7B equivalent, this diode supports compact RF front-end designs requiring low capacitance, fast switching, and stable performance across -55°C to +150°C ambient conditions.
Technical Context
This diode operates as a unidirectional signal switch with cathode-bar marking on the bottom side of its leadless DFN package. Its 2.0 ns reverse recovery time and 0.63 pF junction capacitance enable reliable operation in 1–1000 MHz signal paths, while thermal resistance of 417°C/W (on FR-4) defines power derating above 25°C ambient.
The device uses NiPdAu-plated copper leadframe terminals and meets J-STD-020 Level 1 moisture sensitivity. It exhibits 0.715 V forward voltage at 10 mA and maintains leakage below 0.1 µA at 30 V reverse bias, supporting precision detection and low-loss AC coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRM | 85 V non-repetitive peak reverse voltage - sets absolute maximum transient clamping limit |
| VRRM | 80 V peak repetitive reverse voltage - defines continuous blocking capability in AC/RF signal paths |
| IFM | 300 mA peak forward current - supports pulsed switching in burst-mode RF detectors |
| trr | 2.0 ns typical reverse recovery time - enables clean zero-crossing switching up to ~150 MHz |
| CT | 0.63 pF typical junction capacitance at 0 V - minimizes signal loading in UHF matching networks |
| VF @ 10 mA | 0.715 V forward voltage - ensures low insertion loss in series-switched signal chains |
| RθJA | 417 °C/W thermal resistance - requires derating to 200 mW at 75°C ambient on standard FR-4 layout |
Pinout & Package
Package: X2-DFN1006-2, ultra-small leadless surface-mount package (1.0 × 0.6 × 0.4 mm), cathode marked by bar on bottom side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to input/source side in series-switch configuration; no external marking - identified by absence of cathode bar |
| Cathode | Forward current exit / reverse-blocking terminal | Marked by molded bar on bottom surface; connects to load/ground side; defines polarity in rectifier/detector use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT54C-7-F | Higher VF (0.85 V @ 10 mA), larger SOT-23 package (3.0 × 1.4 mm), 5 ns trr | Less suitable for >500 MHz signal paths due to higher capacitance (10 pF) and slower recovery | Select when board space allows larger footprint and cost sensitivity outweighs RF performance |
| NSR0230HT1G | Lower IFM (200 mA), same DFN1006 but 0.35 pF CT and 1.5 ns trr, RoHS-compliant | Better for sub-GHz low-power detectors where <0.4 pF capacitance improves Q-factor | Prefer for battery-powered sensor nodes needing lowest possible junction capacitance |
Compared with BAT54C-7-F and NSR0230HT1G, the 1SS361LPH4-7B delivers optimal balance of 0.63 pF capacitance, 2.0 ns recovery, and 80 V blocking in the smallest DFN footprint - making it preferred for space-constrained UHF front-ends where both speed and size are critical.

FAQ
What is the cathode identification method for 1SS361LPH4-7B?
The cathode is marked by a molded bar on the bottom surface of the X2-DFN1006-2 package. No top-side marking exists; orientation must be verified using optical inspection or X-ray imaging during automated placement. The anode occupies the opposite terminal, and polarity must be confirmed prior to reflow to avoid functional failure in series-switch configurations.
Can 1SS361LPH4-7B replace BAT54S in existing designs?
No - BAT54S is a dual-series diode in SOT-23, while 1SS361LPH4-7B is a single diode in DFN1006. Direct replacement requires PCB layout revision due to footprint mismatch and pin count difference. Electrical substitution is feasible only if circuit topology uses only one diode section and accommodates 0.4 mm height and 1.0 × 0.6 mm area constraints.
What is the maximum allowable reflow peak temperature?
The 1SS361LPH4-7B supports JEDEC J-STD-020-compliant reflow with a peak temperature of 260°C for ≤30 seconds. Its NiPdAu-plated terminals and UL 94V-0 molding compound ensure intermetallic integrity and flame resistance under standard lead-free profiles. Preheating ramp rate must not exceed 3°C/s to avoid die attach delamination.
Does this diode meet automotive AEC-Q200 requirements?
No - the 1SS361LPH4-7B is not AEC-Q200 qualified. It is rated for industrial temperature range (-55°C to +150°C) and RoHS compliance, but lacks stress test documentation for vibration, temperature cycling, and humidity testing required for automotive qualification. For automotive applications, Diodes' AEC-Q200-qualified alternatives like BAV99WQ-7-F should be considered.
