Product details
Overview
TSS70U RGG from Taiwan Semiconductor is a surface-mount Schottky barrier diode in 0603 package, rated for 70 V repetitive peak reverse voltage, 150 mA average forward current, and 1.0 V typical forward voltage at 15 mA. It delivers low capacitance (49 pF at 0 V), fast reverse recovery (5 ns), and operates from –65 °C to +125 °C - used in compact DC-DC converter output rectification and ESD-sensitive signal line clamping.
For engineers reviewing the TSS70U RGG datasheet, TSS70U RGG pinout, TSS70U RGG application, or TSS70U RGG equivalent, key selection criteria include its 0603 leadless footprint, cathode-band polarity marking, gold-plated solderable terminals per MIL-STD-750 method 2026, halogen-free construction, and 3 mg weight for ultra-thin portable designs.
Technical Context
The TSS70U RGG implements a planar Schottky junction optimized for low forward voltage and fast switching in space-constrained applications. Its 70 V VRRM, 150 mA IO, and 5 ns trr support high-frequency rectification up to several MHz without significant switching loss.
Thermal performance is defined by a –65 °C to +125 °C operating junction range and storage temperature range. The device uses a green compound encapsulant and features gold-plated terminals compatible with standard reflow profiles on glass epoxy PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 70 V - maximum repetitive reverse voltage before breakdown; sets upper limit for clamping or blocking in 24–48 V systems |
| IO | 150 mA - continuous forward current rating at 25 °C ambient; derates linearly above 25 °C per curve in datasheet |
| VF @ 15 mA | 1.00 V typical - low conduction loss enables higher efficiency in low-power rectifiers and OR-ing circuits |
| CJ @ 0 V | 49 pF - minimal junction capacitance preserves signal integrity in RF detector or high-speed data line protection |
| trr | 5 ns - fast recovery reduces switching noise and allows operation in >1 MHz SMPS topologies |
| IR @ 25 V | 0.1 μA typical - low leakage maintains accuracy in precision bias networks and sensor front-ends |
| Package | 0603 (1.6 × 0.8 × 0.75 mm) - ultra-compact, leadless SMD footprint compatible with automated pick-and-place |
Pinout & Package
Package: 0603 surface-mount, leadless, gold-plated terminals, cathode indicated by band. Weight: ~3 mg. Compliant with RoHS 2011/65/EU and halogen-free per IEC 61249-2-21.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Forward current exit / reverse blocking terminal | Marked with band; connects to higher-potential rail; blocks up to 70 V reverse bias with <0.1 μA leakage at 25 V |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-thin 0603 package | 1.6 × 0.8 × 0.75 mm profile enables use in wearables and ultra-slim IoT modules where Z-height is constrained |
| Low forward voltage (1.0 V) | Reduces power loss in battery-powered devices, extending runtime in 3.3 V or 5 V supply rails |
| Fast 5 ns reverse recovery | Minimizes switching tail current and EMI in high-frequency buck converters and charge pumps |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for consumer, industrial, and automotive electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSSR0270MXV6T1G | Same 0603 package, 70 V VRRM, but 200 mA IO and 0.85 V VF @ 15 mA; slightly higher CJ (60 pF) | Better suited for higher-current rectification; less ideal for ultra-low-capacitance signal paths | Select when forward loss reduction outweighs capacitance sensitivity |
| Vishay VS-2EDH07-M3/84A | 0805 package, 70 V VRRM, 200 mA IO, 0.82 V VF; larger footprint and higher thermal mass | Preferred for thermally demanding environments where 0603 self-heating is limiting | Choose when board area permits and thermal derating margin is critical |
Compared with NSSR0270MXV6T1G and VS-2EDH07-M3/84A, the TSS70U RGG offers the smallest footprint and lowest capacitance in the 70 V class, making it optimal for miniaturized, high-frequency, or signal-integrity-critical designs - though with lower current rating and slightly higher VF.

FAQ
What is the maximum junction temperature rating for the TSS70U RGG?
The TSS70U RGG has a specified junction temperature range of –65 °C to +125 °C. This rating is validated per the manufacturer's thermal characterization and applies under steady-state and transient conditions defined in the C1601 datasheet revision. Derating curves for IO versus ambient temperature are provided to ensure safe operation of the TSS70U RGG across its full thermal envelope.
Does the TSS70U RGG have a cathode marking, and how is it identified?
Yes, the TSS70U RGG uses a visible cathode band to indicate polarity. This marking is laser-etched or printed on the device body and aligns with industry-standard orientation for 0603 Schottky diodes. During PCB layout and assembly, the band must be oriented toward the higher-potential node (e.g., VCC) to ensure correct forward biasing of the TSS70U RGG.
Is the TSS70U RGG compliant with RoHS and halogen-free standards?
Yes, the TSS70U RGG complies with the RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The green compound encapsulant and gold-plated terminals meet both material restrictions. These certifications apply to the TSS70U RGG as shipped in its standard 4K/reel packing configuration (RGG suffix).
What is the reverse recovery time (trr) of the TSS70U RGG, and under what test conditions is it measured?
The TSS70U RGG has a typical reverse recovery time of 5 ns. This value is measured under the condition: IF = IR = 10 mA, IRR = 0.1 × IR, RL = 100 Ω, as documented in version C1601 of the TSS70U RGG datasheet. It reflects the diode's ability to transition rapidly from conduction to blocking state in high-frequency switching applications.
Can the TSS70U RGG be used in place of a general-purpose silicon diode like 1N4148 in signal clamping?
No - the TSS70U RGG is a Schottky diode with 70 V VRRM and 1.0 V VF, whereas the 1N4148 is a PN-junction diode with 100 V VRRM and ~0.7 V VF but much higher trr (~4 ns for small-signal switching). While both can clamp, the TSS70U RGG offers lower capacitance (49 pF vs. ~4 pF for 1N4148) and faster recovery, but its lower reverse voltage margin makes direct substitution unsafe in >70 V circuits. Always verify system-level stress on the TSS70U RGG before replacement.
