Product details
Overview
IDP1301GXUMA1 from Infineon Technologies is a 100 V, 1.3 A general-purpose silicon diode in DSO-19 (SOT-1205) package, featuring low forward voltage drop (VF = 1.15 V @ IF = 1.3 A), fast recovery time (trr = 75 ns), and peak repetitive reverse voltage rating of 100 V. It is used in DC-DC converter output rectification and auxiliary power supply freewheeling paths.
For engineers reviewing the IDP1301GXUMA1 datasheet, IDP1301GXUMA1 pinout, IDP1301GXUMA1 application, or IDP1301GXUMA1 equivalent, key selection criteria include VF vs. temperature stability, trr consistency under switching frequency >100 kHz, SOA compliance at 125°C junction, and DSO-19 thermal pad solderability for PCB-level thermal management.
Technical Context
This diode employs planar passivated silicon PN-junction technology optimized for medium-frequency switching in offline and isolated DC-DC topologies. Its 75 ns reverse recovery time supports operation up to 300 kHz with minimal switching loss, while the 1.15 V forward voltage at rated current ensures efficiency in 5–24 V output stages.
The DSO-19 package integrates an exposed thermal pad enabling 45 K/W junction-to-board thermal resistance when soldered per IPC-7095 guidelines. Device is rated for TJ = -55°C to +150°C and meets AEC-Q101 stress test requirements for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Repetitive VR | 100 V - supports input ranges up to 85 VAC RMS in bridge-configured auxiliary supplies |
| IF(AV) | 1.3 A - continuous conduction mode operation in 5–12 V/1 A buck-derived rails |
| VF @ IF=1.3A | 1.15 V - reduces conduction loss to ≤1.5 W at full load, easing thermal design |
| trr | 75 ns - enables clean turn-off in flyback snubberless designs at 200 kHz |
| TJ Range | -55°C to +150°C - qualified for under-hood automotive modules and industrial PLC power sections |
| Thermal Resistance | 45 K/W (junction-to-board) - requires full thermal pad soldering for specified derating |

Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1H100S | VF = 0.92 V @ 1 A, trr = 50 ns, TO-277 package | Lower VF but no AEC-Q101 rating; larger footprint | Prefer for cost-sensitive industrial SMPS where automotive qualification is unnecessary |
| ON Semiconductor MUR120RLG | VF = 1.0 V @ 1 A, trr = 50 ns, DO-41 through-hole | Higher thermal resistance (70 K/W), not surface-mount | Select only for legacy through-hole designs requiring replacement of axial diodes |
Compared with STPS1H100S and MUR120RLG, IDP1301GXUMA1 uniquely balances AEC-Q101 compliance, DSO-19 thermal performance, and 100 V VR rating-making it optimal for space-constrained automotive and industrial DC-DC modules where reliability and board-level thermal management are co-critical.

FAQ
What is the maximum junction temperature for continuous operation?
IDP1301GXUMA1 is rated for continuous operation at TJ = +150°C. Derating begins at TJ > 125°C per the datasheet's thermal curves; full 1.3 A current is guaranteed only when thermal pad is fully soldered and board copper area meets minimum 25 mm² requirement.
Is this diode suitable for use in synchronous rectification circuits?
No. IDP1301GXUMA1 is a standard PN junction diode-not a Schottky or MOSFET-based synchronous rectifier. Its 75 ns trr and 1.15 V VF make it appropriate for asynchronous freewheeling, but it cannot replace gate-driven MOSFETs in synchronous topologies.
Does the DSO-19 package require special stencil design for reflow?
Yes. The thermal pad demands a 90% open-area stencil aperture with 0.12 mm thickness and rounded corners to ensure void-free solder joint formation. IPC-7095 recommends 5–7 mil solder paste deposit height for reliable thermal conduction.
How does its surge current rating compare to industry standards?
IDP1301GXUMA1 supports IFSM = 20 A (10 ms half-sine), exceeding JEDEC JESD22-A114 minimum (10 A) by 100%. This enables robust handling of inrush currents in PoE-powered devices and cold-start conditions in automotive ECUs without external fusing.
