Product details
Overview
1SS220(0)-T1B-A from Renesas Electronics is a high-speed switching diode in a small SOD-323 (SC-76) surface-mount package, rated for 80 V reverse voltage, 150 mA average forward current, and 4 ns reverse recovery time. It serves as a signal-level rectifier or clamp in digital logic interfaces and low-power RF detection circuits.
For engineers reviewing the 1SS220(0)-T1B-A datasheet, 1SS220(0)-T1B-A pinout, 1SS220(0)-T1B-A application, or 1SS220(0)-T1B-A equivalent, key selection criteria include its fast recovery performance, low forward voltage drop at 10 mA, and guaranteed junction temperature range of −55°C to +150°C under specified operating conditions.
Technical Context
This diode employs a planar epitaxial silicon structure optimized for high-speed switching in low-current signal paths. Its 4 ns reverse recovery time (trr) and 0.95 V typical forward voltage (VF) at IF = 10 mA enable clean edge transitions in 3.3 V and 5 V logic-level clamping applications.
The device operates with a maximum junction temperature of +150°C and exhibits a leakage current (IR) of ≤100 nA at 80 V and 25°C - critical for maintaining signal integrity in battery-powered sensor front-ends and low-duty-cycle pulse detection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max) | 80 V - supports rail-to-rail signal clamping in 24 V industrial I/O and 5 V logic interfaces without breakdown |
| IF(AV) | 150 mA - sufficient for driving LED indicators or biasing small-signal transistors in portable equipment |
| trr | 4 ns - enables reliable operation up to ~100 MHz switching frequencies in RF detector and sample-hold circuits |
| VF @ 10 mA | 0.95 V (typ) - minimizes power loss and voltage offset in precision analog signal routing |
| IR @ 80 V | ≤100 nA @ 25°C - ensures negligible leakage-induced error in high-impedance sensor conditioning paths |
| Tj Range | −55°C to +150°C - qualified for under-hood automotive modules and industrial motor control PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | Lower VR (30 V), higher IF(AV) (200 mA), same SOD-323 package | Better suited for 3.3 V/5 V logic only; not rated for 24 V industrial clamping | Select when operating voltage stays below 30 V and higher forward current margin is needed |
| BAS16W,115 | Higher VR (100 V), slower trr (4 ns typical but 6 ns max), same SOD-323 | Acceptable for general-purpose switching but less consistent at >50 MHz due to trr variation | Choose when 100 V standoff is mandatory and sub-5 ns consistency is non-critical |
Compared with RB520S-30T1G and BAS16W,115, the 1SS220(0)-T1B-A uniquely balances 80 V standoff, 4 ns trr consistency, and −55°C to +150°C operation - making it optimal for industrial I/O protection where voltage margin, speed, and thermal robustness are simultaneously required.

FAQ
What is the maximum reverse voltage rating for the 1SS220(0)-T1B-A?
The 1SS220(0)-T1B-A has a maximum repetitive peak reverse voltage (VRRM) of 80 V. This rating is validated per JEDEC test conditions and applies across the full operating temperature range of −55°C to +150°C. Exceeding this voltage may cause irreversible avalanche breakdown. The 1SS220(0)-T1B-A must be used within this limit in all circuit designs, including transient suppression and DC blocking applications.
Does the 1SS220(0)-T1B-A have a specified reverse recovery time?
Yes, the 1SS220(0)-T1B-A specifies a typical reverse recovery time (trr) of 4 ns at IF = 10 mA, IR = 10 mA, and di/dt = 100 A/μs. This value is measured under standardized conditions and confirms suitability for high-frequency signal routing. The 1SS220(0)-T1B-A maintains this performance without derating up to +125°C junction temperature.
What package type is used for the 1SS220(0)-T1B-A?
The 1SS220(0)-T1B-A uses the SOD-323 (also known as SC-76) surface-mount plastic package. It measures 1.7 mm × 1.25 mm × 0.9 mm and features a cathode band marking on the top surface. The 1SS220(0)-T1B-A's SOD-323 footprint is compatible with standard reflow profiles and automated pick-and-place equipment used in high-volume PCB assembly.
What is the forward voltage drop of the 1SS220(0)-T1B-A at 10 mA?
The 1SS220(0)-T1B-A exhibits a typical forward voltage (VF) of 0.95 V at IF = 10 mA and Tj = 25°C. This value increases to approximately 1.05 V at +125°C junction temperature. The 1SS220(0)-T1B-A's low VF minimizes power dissipation in signal-path clamping and biasing applications where efficiency and thermal management are critical.
Is the 1SS220(0)-T1B-A suitable for automotive applications?
The 1SS220(0)-T1B-A is qualified for "Standard" grade applications per Renesas' quality classification, which includes industrial robots and transportation equipment excluding safety-critical systems. While it operates from −55°C to +150°C and meets AEC-Q200 stress test recommendations for discrete diodes, it is not AEC-Q101 qualified. For non-safety automotive subsystems like body control or infotainment I/O, the 1SS220(0)-T1B-A may be used subject to customer qualification - but the 1SS220(0)-T1B-A itself carries no formal automotive qualification mark.
