Product details
Overview
PU2DLSH from Taiwan Semiconductor is a 2 A, 200 V ultra-fast surface-mount rectifier diode in SOD-123HE package, featuring 25 ns reverse recovery time, 0.87 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency freewheeling or snubber diode in DC/DC converters operating up to several hundred kHz.
For engineers reviewing the PU2DLSH datasheet, PU2DLSH pinout, PU2DLSH application, or PU2DLSH equivalent, key selection criteria include its 200 V VRRM, 50 A IFSM, 175 °C TJMAX, low Qrr of 31 nC, and SOD-123HE thermal performance (RθJL = 14 °C/W).
Technical Context
This device is a single-die, planar-junction silicon rectifier optimized for high-frequency switching applications. Its ultra-fast recovery (trr ≤ 25 ns) and low reverse recovery charge (Qrr = 31 nC) minimize switching losses in hard-switched topologies, while the 200 V VRRM rating supports 150 V bus designs with margin.
The SOD-123HE package delivers enhanced thermal performance over standard SOD-123 - RθJL = 14 °C/W and RθJA = 79 °C/W on 5 mm × 5 mm Cu pad - enabling sustained 2 A conduction at elevated ambient temperatures without forced cooling.
Key Specifications

| VRRM | 200 V - supports 150 V nominal DC bus with 33% safety margin for transient spikes |
| IF | 2 A continuous - rated for steady-state conduction in compact power stages |
| trr | 25 ns - enables efficient operation in 200–500 kHz DC/DC converters |
| Qrr | 31 nC - reduces turn-on loss in synchronous rectifier or MOSFET-based topologies |
| VF @ 2 A, 25°C | 0.87 V - contributes to <1.74 W conduction loss per diode at full load |
| TJMAX | 175 °C - allows operation in under-hood automotive environments |
| RθJL | 14 °C/W - enables direct PCB heat sinking via cathode pad for thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02DJF | Same SOD-123HE package, 200 V VRRM, but trr = 35 ns and Qrr = 42 nC | Higher switching loss in >250 kHz designs; less suitable for GaN-driven topologies | Preferred where cost sensitivity outweighs 10 ns trr advantage and layout allows minor thermal margin increase |
| ES2D-E3/57T | DO-214AA package, 200 V VRRM, trr = 35 ns, Qrr = 45 nC, RθJA = 100 °C/W | Larger footprint and inferior thermal resistance limit usable current density in space-constrained boards | Applicable when legacy DO-214AA layout exists and 2 A average current is derated to 1.5 A at 70 °C ambient |
Compared with STTH2R02DJF and ES2D-E3/57T, PU2DLSH offers the lowest Qrr and best thermal resistance in SOD-123HE, making it optimal for high-density, high-frequency automotive and telecom power stages where switching loss and junction temperature are critical constraints.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for PU2DLSH?
The PU2DLSH has a VRRM rating of 200 V, verified per Taiwan Semiconductor's B2109 datasheet. This value is explicitly assigned to PU2DLSH in the Absolute Maximum Ratings table and distinguishes it from the 100 V PU2BLSH variant. The 200 V rating provides design margin for 150 V bus systems subject to ISO 7637-2 load dump transients.
Is PU2DLSH qualified for automotive applications?
Yes, PU2DLSH is AEC-Q101 qualified, as confirmed in the FEATURES section of the official datasheet. This qualification covers stress tests including HTGB, HTRB, TCT, and mechanical shock, validating its suitability for automotive powertrain and body electronics where reliability under thermal cycling and vibration is critical.
What is the reverse recovery time (trr) of PU2DLSH, and under what conditions is it measured?
The PU2DLSH reverse recovery time is specified as ≤25 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the Electrical Specifications table. An alternate condition (IF = 1.0 A, di/dt = 50 A/µs, VR = 30 V) yields 30 ns - both values are documented in the same datasheet revision B2109 for PU2DLSH.
Does PU2DLSH have a halogen-free construction?
Yes, PU2DLSH is halogen-free in accordance with IEC 61249-2-21, as stated in the FEATURES section of the official datasheet. This confirms compliance with environmental standards for RoHS-compliant manufacturing and end-of-life processing without release of hazardous halogenated gases.
What is the thermal resistance from junction to lead (RθJL) for PU2DLSH?
The junction-to-lead thermal resistance (RθJL) for PU2DLSH is 14 °C/W, measured on a standard 5 mm × 5 mm copper pad PCB per the Thermal Performance table. This value is identical for both PU2BLSH and PU2DLSH variants and enables effective conduction cooling through the cathode terminal in SOD-123HE mounting.
