Product details
Overview
TMBYV10-60FILM from STMicroelectronics is a small-signal Schottky diode in MELF glass package, designed for low-voltage switching-mode power supplies and polarity protection circuits. It features 60 V repetitive peak reverse voltage (VRRM), 1 A average forward current (IF(AV)), 0.7 V typical forward voltage at 1 A, and 40 A surge current capability with 300 µs rectangular pulse.
For engineers reviewing the TMBYV10-60FILM datasheet, TMBYV10-60FILM pinout, TMBYV10-60FILM application, or TMBYV10-60FILM equivalent, key selection criteria include low VF for efficiency-critical DC/DC converters, fast recovery behavior without minority-carrier storage charge, thermal resistance of 110 °C/W, and MELF glass package suitability for high-reliability industrial and telecom power stages.
Technical Context
This Schottky diode operates via majority-carrier conduction, eliminating reverse recovery charge (Qrr) and enabling clean switching in high-frequency (>100 kHz) SMPS topologies. Its junction capacitance varies from 150 pF at 0 V to 40 pF at 5 V reverse bias, directly influencing snubber design and EMI performance.
The device's thermal design is constrained by a junction-to-leads thermal resistance of 110 °C/W and a maximum lead temperature of 260 °C for 15 s soldering. Junction temperature must remain within –65 °C to +125 °C under continuous operation, with storage extended to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking voltage before breakdown; sets usable input range in 48 V or 24 V DC/DC front-ends |
| IF(AV) | 1 A at Ti = 25 °C - Continuous forward current rating; defines steady-state power dissipation limit |
| VF | 0.7 V typ. at IF = 1 A - Low conduction loss improves efficiency in low-voltage synchronous rectification |
| IFSM | 40 A rectangular pulse (300 µs) - Supports transient overload handling in POL converters |
| Cj | 40 pF at VR = 5 V - Junction capacitance impacts switching node ringing and gate drive interaction |
| Rth(j–l) | 110 °C/W - Thermal resistance from junction to leads; determines temperature rise under 1 A DC load |
Pinout & Package
MELF (Metal Electrode Leadless Face) glass package: cylindrical hermetically sealed body with axial cathode ring marking; dimensions ØB = 2.50–2.65 mm, length A = 4.80–5.20 mm, weight 0.15 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side in polarity protection; requires low-inductance layout to minimize VF error |
| Cathode | Forward current exit / reverse blocking terminal | Marked by black ring; ties to system ground or higher-potential rail in reverse-biased protection schemes |
Key Features
| Feature | Design Value |
|---|---|
| Majority-carrier conduction | Eliminates Qrr-driven switching losses and associated EMI spikes in high-frequency converters |
| Low VF (0.7 V @ 1 A) | Reduces conduction loss by ~30% vs. comparable PN diodes, improving light-load efficiency in 5–12 V outputs |
| MELF glass construction | Enables stable parameter drift over temperature and humidity; rated for industrial-grade reliability |
| 110 °C/W Rth(j–l) | Allows direct PCB pad thermal coupling without heatsink in space-constrained 1 A applications |
Applications
| DC/DC Converter Output Rectification | Polarity Protection Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 3.3–12 V at ≤1 A. IC Role / Device Role / Timing Role: Uncontrolled rectifier replacing synchronous MOSFETs where cost and simplicity outweigh marginal efficiency gain. Use Value: 0.7 V VF minimizes output voltage drop and thermal stress versus PN diodes, enabling smaller output capacitors. | Use Scenario: Reverse-voltage blocking on 24 V industrial sensor inputs or fieldbus nodes. IC Role / Device Role / Timing Role: Series-connected anode-to-input protection element preventing damage during cable miswiring. Use Value: 60 V VRRM provides 2× margin over 24 V nominal rails; MELF glass withstands repeated surge events per IEC 61000-4-5. |
| High-Frequency Snubber Network | RF Detector / Mixer Clamp |
Use Scenario: RC snubber across MOSFET drains in 200–500 kHz resonant LLC converters. IC Role / Device Role / Timing Role: Fast-turn-off clamp limiting dv/dt-induced oscillation amplitude during turn-off transitions. Use Value: 40 pF Cj at 5 V enables predictable snubber time constant tuning without parasitic resonance. | Use Scenario: Signal-level clamping in 10–100 MHz RF detector stages for wireless sensor transceivers. IC Role / Device Role / Timing Role: Low-capacitance, low-VF limiter preventing op-amp input saturation during RF envelope peaks. Use Value: 150 pF Cj at 0 V supports wideband response; absence of Qrr avoids distortion in AM demodulation paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1L60 | TO-220AC package; 60 V VRRM, 1 A IF(AV), 0.72 V VF @ 1 A, but Rth(j–c) = 50 °C/W | Requires heatsink above 0.5 A; unsuitable for compact MELF footprint layouts | Select when board space allows TO-220 mounting and thermal mass improves long-term reliability |
| SS14 | SMA package; 40 V VRRM, 1 A IF(AV), 0.5 V VF @ 1 A, Cj = 110 pF @ 4 V | Limited to ≤24 V systems; higher capacitance increases switching loss in >1 MHz designs | Select for cost-sensitive 5–12 V USB PD adapters where 40 V rating suffices and VF priority exceeds speed |
Compared with STPS1L60 and SS14, TMBYV10-60FILM uniquely balances MELF reliability, 60 V rating, and 40 pF capacitance-making it optimal for compact, high-frequency industrial power modules where thermal cycling and layout density are critical.

FAQ
Is TMBYV10-60FILM suitable for synchronous rectification replacement?
No. TMBYV10-60FILM is a passive Schottky rectifier-not a synchronous rectifier controller or MOSFET driver. It replaces PN diodes in non-controlled rectification roles. Synchronous rectification requires active gate control, which this device does not provide.
What is the maximum allowable PCB trace width for 1 A continuous operation?
With Rth(j–l) = 110 °C/W and 0.7 V VF, power dissipation is 0.7 W. For ≤30 °C rise, minimum copper area is 40 mm² (e.g., 2 mm × 20 mm, 2 oz Cu). Thermal vias to inner ground planes further reduce junction temperature.
Does TMBYV10-60FILM have a specified reverse recovery time (trr)?
No trr is specified because Schottky conduction relies on majority carriers-no minority-carrier storage charge exists. The datasheet explicitly states reverse recovery is governed only by junction capacitance charging, not Qrr-based delay.
Can TMBYV10-60FILM be reflow soldered using standard lead-free profiles?
Yes. The MELF glass package supports peak reflow temperatures up to 260 °C for 15 s, matching IPC/JEDEC J-STD-020D. Preheat and soak phases must stay below 200 °C to avoid thermal shock cracking of the glass body.
