Product details

Overview

TMM6263FILM from STMicroelectronics is a small-signal Schottky diode in MINIMELF glass package, featuring 60 V repetitive peak reverse voltage (V_RRM), 0.41 V forward voltage at 1 mA (V_F), and 2.2 pF junction capacitance at 0 V. It delivers ultrafast switching (100 ps recovery time) and low leakage (0.2 µA at 50 V), optimized for UHF/VHF detection and pulse applications in RF front-ends.

For engineers reviewing the TMM6263FILM datasheet, TMM6263FILM pinout, TMM6263FILM application, or TMM6263FILM equivalent, key selection criteria include its low V_F, sub-3 pF C_j, 100 ps τ, -65 to 200 °C operating range, and glass MINIMELF thermal robustness for high-frequency detector and sampling circuits.

Technical Context

This Schottky diode uses a metal-to-silicon junction to achieve low turn-on voltage and minimal minority-carrier storage, enabling nanosecond-scale switching. Its 100 ps reverse recovery time (τ) and 2.2 pF capacitance at 0 V support operation up to UHF bands without significant signal distortion.

The device operates across -65 to 200 °C junction temperature, with 400 °C/W junction-to-leads thermal resistance and 260 °C soldering tolerance. It is rated for 15 mA continuous forward current and withstands 50 mA non-repetitive surge pulses ≤1 s.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum reverse voltage before breakdown; enables use in 50 V RF bias and detection rails.
V_F @ 1 mA	0.41 V - Low forward drop improves detector sensitivity and reduces power loss in low-current signal paths.
C_j @ 0 V	2.2 pF - Minimal junction capacitance preserves high-frequency impedance matching in UHF/VHF circuits.
τ (Recovery)	100 ps - Ultrafast switching supports pulse edge fidelity and broadband sampling applications.
I_R @ 50 V	0.2 µA - Low leakage maintains signal integrity in high-impedance detector nodes.
T_j Range	-65 to 200 °C - Wide thermal capability suits under-hood automotive sensors and industrial RF modules.

Pinout & Package

Package: MINIMELF glass package (SOD-523 equivalent footprint), cathode marked by ring at one end. Leads are axial, with anode and cathode terminals on opposite ends of the cylindrical glass body.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to RF input or bias source in detector configurations; polarity-sensitive for rectification.
Cathode	Forward current exit / reverse blocking terminal	Marked with ring; tied to ground or reference node in series-detector topologies.

Key Features

Feature	Design Value
Ultra-low V_F	0.41 V at 1 mA enables high-efficiency RF envelope detection with minimal signal compression.
Sub-3 pF C_j	2.2 pF at 0 V ensures minimal loading on 50 Ω transmission lines up to 1 GHz.
100 ps recovery	Enables accurate pulse sampling and fast-rise-time signal demodulation without tailing artifacts.
200 °C max T_j	Supports placement near heat-generating RF power stages without derating or thermal shutdown.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky detector applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAT54W,115	Higher C_j (10 pF @ 0 V), higher V_F (0.8 V @ 10 mA), SOT-323 package	Less suitable for >500 MHz detection due to capacitance; better for general-purpose logic-level clamping	Select when board space allows larger SOT-323 and frequency <300 MHz
NSR0230HT1G	Lower V_RRM (30 V), same V_F (0.41 V), SOD-523 package	Not rated for 50 V bias rails; limited to low-voltage RF sensing	Choose only if system reverse voltage stays below 25 V and thermal margin is constrained

Compared with BAT54W and NSR0230HT1G, TMM6263FILM uniquely balances 60 V V_RRM, 2.2 pF C_j, and 100 ps τ in a glass MINIMELF package-making it the only option qualified for high-dynamic-range UHF pulse detection above 500 MHz with industrial temperature resilience.

FAQ

Is TMM6263FILM suitable for 900 MHz ISM band applications?

Yes. With 2.2 pF junction capacitance and 100 ps reverse recovery time, TMM6263FILM maintains low insertion loss and minimal phase distortion at 900 MHz, making it appropriate for envelope detection and sampling in ISM-band transceivers and sensor nodes.

What is the marking convention for cathode identification?

The cathode is identified by a distinct color ring at one end of the MINIMELF glass body. This marking aligns with JEDEC-standard SOD-523 orientation and is visible under standard optical inspection during manual or automated assembly.

Can TMM6263FILM be used in reflow soldering processes?

Yes. The device is rated for a maximum soldering temperature of 260 °C for 15 seconds, fully compatible with standard lead-free reflow profiles (e.g., IPC/JEDEC J-STD-020). Glass-body construction ensures no internal delamination under thermal cycling.

Does STMicroelectronics offer matched diode pairs for balanced detector designs?

Yes. Matched batches of TMM6263FILM are available on request per datasheet footnote, with guaranteed V_F and C_j tracking within ±5% across pairs-enabling high-common-mode-rejection quadrature detectors and precision RF sampling bridges.
