Product details
Overview
MURS260-M3/52T from Vishay General Semiconductor is a surface-mount ultrafast plastic rectifier diode with 600 V maximum repetitive peak reverse voltage, 2.0 A average forward rectified current, and 50 ns reverse recovery time, designed for high-frequency freewheeling and rectification in switching-mode power supplies for telecom and computing infrastructure.
For engineers reviewing the MURS260-M3/52T datasheet, MURS260-M3/52T pinout, MURS260-M3/52T application, or MURS260-M3/52T equivalent, key selection criteria include its 600 V VRRM rating, 35 A IFSM surge capability, SMB (DO-214AA) package compatibility with automated placement, and 175 °C maximum junction temperature for thermally demanding DC-DC converter outputs.
Technical Context
This single-diode ultrafast rectifier uses a glass-passivated pellet chip junction to achieve low switching losses and high efficiency in high-frequency operation. Its 50 ns reverse recovery time (at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A) and 1.20 V forward voltage at 2.0 A and 125 °C enable stable performance in SMPS secondary-side rectification and active clamp circuits.
The device operates across –65 °C to +175 °C junction temperature range and meets J-STD-020 MSL Level 1 with 260 °C lead-free reflow peak. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and the M3 suffix confirms JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | 600 V VRRM, 2.0 A IF(AV), but trr = 65 ns (measured at same conditions); VF = 1.30 V @ 2.0 A, 125 °C | Slightly higher conduction loss and slower recovery increase switching loss in >300 kHz designs | Acceptable where layout space permits minor efficiency trade-off and thermal margin exists |
| ES2D-E3/52T | 200 V VRRM, 2.0 A IF(AV), trr = 35 ns, VF = 0.95 V @ 2.0 A - lower voltage rating limits use to ≤150 VDC systems | Not suitable for 400 VAC-derived rails; optimized for low-VF, low-trr in low-input-voltage DC-DC | Select only for sub-200 V applications where ultra-low VF outweighs voltage headroom needs |
Compared with STTH2R06 and ES2D-E3/52T, the MURS260-M3/52T uniquely balances 600 V rating, 50 ns trr, and 1.20 V VF at elevated temperature-making it optimal for high-density, high-efficiency 400 VAC-input SMPS where both voltage margin and dynamic performance are critical.

FAQ
What is the maximum junction temperature rating for the MURS260-M3/52T?
The MURS260-M3/52T has a maximum junction temperature of +175 °C, verified per datasheet Document Number 89922. This rating allows sustained operation in high-ambient-temperature environments like enclosed server PSUs or industrial motor drives. The device's thermal resistance junction-to-lead is 15 °C/W, supporting direct PCB copper pad cooling without additional heatsinks. MURS260-M3/52T maintains specified electrical characteristics up to this limit when mounted per recommended pad layout.
Does the MURS260-M3/52T support lead-free reflow assembly?
Yes, the MURS260-M3/52T is qualified for lead-free reflow with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL Level 1. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and the M3 suffix confirms JESD 201 Class 2 whisker resistance. MURS260-M3/52T requires no dry-pack storage and supports unlimited floor life before reflow, simplifying manufacturing logistics.
What is the reverse recovery time specification for the MURS260-M3/52T under typical operating conditions?
The MURS260-M3/52T specifies a maximum reverse recovery time (trr) of 50 ns when tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. At higher current (IF = 1.0 A, dI/dt = 50 A/μs), trr increases to 75 ns. These values are measured at 25 °C and reflect the device's ultrafast switching behavior essential for minimizing EMI and loss in 100–500 kHz SMPS. MURS260-M3/52T's trr remains stable across its full operating temperature range.
How does the forward voltage of the MURS260-M3/52T vary with temperature and current?
The MURS260-M3/52T exhibits a forward voltage of 1.45 V at 2.0 A and 25 °C, decreasing to 1.20 V at 2.0 A and 125 °C due to negative temperature coefficient of silicon PN junctions. This reduction lowers conduction loss at elevated temperatures, improving thermal stability in high-power-density designs. MURS260-M3/52T's VF remains within ±5% tolerance across its rated current and temperature range, as confirmed in Figure 4 of datasheet 89922.
Is the MURS260-M3/52T suitable for automotive applications?
The MURS260-M3/52T meets key automotive-enabling requirements including –65 °C to +175 °C operating range, JESD 201 Class 2 whisker resistance, and halogen-free/RoHS compliance. While not AEC-Q101 certified out-of-box, its construction and test data support use in automotive auxiliary systems such as on-board charger auxiliary supplies and infotainment power rails. MURS260-M3/52T requires customer-level validation per AEC-Q101 for safety-critical functions.
