Product details
Overview
1SS119-14TA-E from Renesas is a silicon epitaxial planar switching diode in a miniature MHD glass package, rated for 30 V reverse voltage, 150 mA average forward current, and featuring 3.0 pF max capacitance and 3.5 ns max reverse recovery time. It serves as a high-speed signal path switch in RF front-ends and digital logic interface circuits.
For engineers reviewing the 1SS119-14TA-E datasheet, 1SS119-14TA-E pinout, 1SS119-14TA-E application, or 1SS119-14TA-E equivalent, key selection criteria include low junction capacitance, fast trr performance under 10 mA/6 V test conditions, cathode-band polarity marking, and MHD package compatibility with automated placement systems.
Technical Context
This diode uses an epitaxial planar structure to achieve low stored charge and rapid carrier recombination, enabling sub-4 ns reverse recovery. Its MHD glass package provides hermetic sealing and thermal stability up to 175°C junction temperature.
Designed for small-signal switching-not power rectification-the 1SS119-14TA-E operates with VF ≤ 0.8 V at 10 mA and IR ≤ 0.1 µA at 30 V, supporting low-leakage, high-isolation signal routing in broadband applications.

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 |
|---|---|---|---|
| 1N4148W-7-F | Higher trr (4.0 ns max), same M7 package but SOD-123 outline; VF = 1.0 V @ 10 mA | Marginally slower recovery limits use above 80 MHz; higher VF increases clamp voltage error | Acceptable where cost sensitivity outweighs 0.5 ns trr advantage and 0.2 V VF penalty |
| BAT54C | Dual common-cathode Schottky; VF = 0.33 V typ, but C = 10 pF min - no trr specification | Lower VF benefits clamping, but higher capacitance degrades RF bandwidth beyond 300 MHz | Preferred for low-VF DC clamping; unsuitable for >500 MHz signal switching due to capacitance |
Compared with 1SS119-14TA-E, the 1N4148W-7-F trades speed for broader availability, while BAT54C offers lower forward drop at the expense of RF bandwidth-making 1SS119-14TA-E optimal for sub-1 GHz high-fidelity switching where both trr and C are simultaneously constrained.

FAQ
What is the maximum reverse recovery time specified for the 1SS119-14TA-E?
The 1SS119-14TA-E has a maximum reverse recovery time (trr) of 3.5 ns, measured under standardized conditions: IF = 10 mA, VR = 6 V, RL = 50 Ω. This value is guaranteed across the full operating temperature range and is critical for maintaining signal fidelity in high-frequency switching applications. The 1SS119-14TA-E achieves this performance via its silicon epitaxial planar structure and optimized doping profile.
Does the 1SS119-14TA-E have a cathode band, and how is it identified?
Yes, the 1SS119-14TA-E features a light blue cathode band on the MHD glass package, positioned adjacent to pin 1. Pin 1 is the cathode terminal, and pin 2 is the anode. This marking is essential for correct orientation during PCB assembly and ensures proper polarity in clamping, detection, and switching configurations. The 1SS119-14TA-E's cathode identification complies with JEITA standard GRZZ0002ZC-A.
What is the junction capacitance of the 1SS119-14TA-E, and under what conditions is it measured?
The 1SS119-14TA-E exhibits a maximum junction capacitance (C) of 3.0 pF, measured at VR = 1 V and f = 1 MHz. This low capacitance is intrinsic to its epitaxial planar construction and enables minimal signal attenuation in RF paths up to 1 GHz. The 1SS119-14TA-E's C parameter is tightly controlled and verified per Renesas' Rev. 3.00 test methodology.
Can the 1SS119-14TA-E be used in surface-mount reflow processes?
Yes, the 1SS119-14TA-E's MHD glass package is qualified for standard lead-free reflow soldering profiles, including peak temperatures up to 260°C for ≤10 seconds. Its hermetic seal and thermal stability (Tj = −65°C to +175°C) ensure reliability through multiple thermal cycles. The 1SS119-14TA-E is commonly placed using pick-and-place machines compatible with 2.0 mm diameter components.
What is the maximum average forward current rating for the 1SS119-14TA-E?
The 1SS119-14TA-E is rated for an average forward current (IO) of 150 mA at Ta = 25°C. Derating is required above ambient temperatures per the thermal resistance curve in the datasheet, but the device maintains full IO capability up to 75°C ambient when mounted on standard FR-4 with minimal copper area. This rating supports sustained operation in logic interface and detector circuits where the 1SS119-14TA-E is routinely deployed.
