Product details
Overview
RS2DAH from Taiwan Semiconductor is a 200 V, 1.5 A fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the RS2DAH datasheet, RS2DAH pinout, RS2DAH application, or RS2DAH equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (RθJL = 18 °C/W), junction temperature range (–55 to +175 °C), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The RS2DAH employs a glass-passivated single-die silicon junction optimized for fast switching in high-frequency DC/DC converters and snubber circuits. Its 150 ns trr and low 50 pF junction capacitance support efficient operation up to several hundred kHz.
Designed for automotive-grade reliability, the device meets AEC-Q101 stress tests and features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band on the DO-214AC body.
Key Specifications

Applications
| Automotive LED Lighting | DC/DC Converter Output Rectification |
|---|---|
Use Scenario: High-brightness LED headlamp modules requiring compact, thermally robust rectification in space-constrained housings. IC Role / Device Role / Timing Role: Freewheeling diode in buck-derived constant-current drivers; handles 1.5 A pulsed output with minimal voltage overshoot. Use Value: 150 ns trr and 200 V VRRM suppress inductive kickback during MOSFET turn-off, improving LED lifetime and EMI profile. | Use Scenario: Secondary-side synchronous rectification replacement in isolated 12 V → 3.3 V/5 V flyback converters for infotainment ECUs. IC Role / Device Role / Timing Role: Output rectifier conducting continuous 1.5 A load; operates at 100–300 kHz switching frequency. Use Value: Low 1.3 V VF and 18 °C/W RθJL reduce conduction loss and enable direct thermal coupling to PCB ground plane. |
| Snubber Network Clamp | General-Purpose AC/DC Bridge Leg |
Use Scenario: RCD snubber across primary-side MOSFETs in automotive OBC pre-regulators to absorb leakage inductance energy. IC Role / Device Role / Timing Role: Fast-recovery clamp diode absorbing high dv/dt transients; must recover before next switching cycle. Use Value: 150 ns trr ensures full recovery within typical 500 ns dead-time windows, preventing voltage doubling and MOSFET overstress. | Use Scenario: Single-leg rectification in low-power auxiliary AC/DC supplies for body control modules. IC Role / Device Role / Timing Role: Half-wave rectifier handling 1.5 A average current from 24 V AC transformer secondaries. Use Value: DO-214AC footprint and J-STD-020 Level 1 allow direct placement into existing SMA-reflow lines without process change. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06F | 600 V VRRM, 1.1 A IF, 75 ns trr, TO-277 package | Higher voltage rating but lower current; faster recovery; different thermal path | Preferred where higher VRRM margin or faster switching is required, but requires layout revision due to TO-277 footprint |
| MBR15200CT | 200 V VRRM, 15 A total (dual 7.5 A), Schottky, TO-220AB | Higher current, zero Qrr, but no AEC-Q101 qualification and higher VF at elevated TJ | Suitable for non-automotive 200 V systems needing higher current; not recommended for under-hood use due to lack of AEC-Q101 and thermal derating limitations |
Compared with STTH1L06F and MBR15200CT, the RS2DAH uniquely balances 200 V rating, 1.5 A current, 150 ns recovery, AEC-Q101 compliance, and DO-214AC manufacturability-making it optimal for cost-sensitive, space-constrained automotive power stages where full Schottky performance isn't required.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for RS2DAH?
The RS2DAH has a VRRM of 200 V, verified per the Taiwan Semiconductor datasheet Version B2304. This rating defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions. Exceeding this value risks avalanche failure, especially at elevated junction temperatures. The RS2DAH is part of a family spanning 50 V to 1000 V, with RS2DAH specifically designated for 200 V applications.
Is RS2DAH qualified for automotive applications?
Yes, RS2DAH is AEC-Q101 qualified, as explicitly stated in the official Taiwan Semiconductor documentation. This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST). The device is intended for automotive subsystems such as LED lighting and DC/DC converters where reliability under thermal and mechanical stress is critical. RS2DAH maintains its full specification over –55 to +175 °C junction temperature range.
What is the reverse recovery time (trr) of RS2DAH and how is it measured?
The RS2DAH has a maximum reverse recovery time (trr) of 150 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Taiwan Semiconductor datasheet. This parameter reflects the time required for the diode to transition from forward conduction to reverse blocking state. The 150 ns value enables efficient operation in switching frequencies up to ~300 kHz, making RS2DAH suitable for high-frequency DC/DC converters and snubber circuits.
What package type does RS2DAH use and what are its key mechanical features?
RS2DAH uses the DO-214AC (SMA) surface-mount package, confirmed by mechanical drawings and ordering information in the Taiwan Semiconductor datasheet. Key features include UL 94V-0 flammability-rated molding compound, matte tin-plated leads compliant with J-STD-002, cathode polarity indicated by a molded band, and a weight of approximately 0.060 g. The package outline matches JEDEC DO-214AC standards, with defined pad layout recommendations for reliable reflow soldering.
Does RS2DAH have RoHS and halogen-free compliance?
Yes, RS2DAH is RoHS compliant and halogen-free, as documented in the "Features" section of the Taiwan Semiconductor datasheet. Compliance is verified per EU Directive 2011/65/EU and IEC 61249-2-21:2013. The halogen-free status means bromine and chlorine content are each below 900 ppm, and total halogens are below 1500 ppm-supporting environmental safety and compatibility with lead-free reflow processes. This applies to the RS2DAH device itself, not just the packaging materials.
