Product details
Overview
HS2DAH from Taiwan Semiconductor is a 200V, 1.5A surface-mount fast recovery rectifier diode in DO-214AC (SMA) package, featuring 50 ns reverse recovery time, 1.0 V forward voltage at 1.5 A, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC-DC converters and car lighting systems.
For engineers reviewing the HS2DAH datasheet, HS2DAH pinout, HS2DAH application, or HS2DAH equivalent, key selection criteria include repetitive peak reverse voltage (200 V), junction-to-ambient thermal resistance (80 °C/W), moisture sensitivity level (MSL 1), and compliance with JESD201 Class 2 whisker testing.
Technical Context
The HS2DAH employs a glass-passivated single-die silicon junction optimized for fast switching and low conduction loss. Its 50 ns trr and 1.0 V VF at 1.5 A enable high-efficiency operation in medium-voltage power conversion stages where thermal management and dynamic losses are critical.
Designed for automotive environments, the device meets AEC-Q101 stress test requirements and operates across –55°C to +150°C junction temperature range. Its DO-214AC (SMA) package supports automated placement and provides UL 94V-0 flammability rating with matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VRRM | 200 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in snubber/freewheeling circuits |
| IF | 1.5 A - Continuous forward current rating; determines steady-state power handling capability |
| trr | 50 ns - Reverse recovery time; directly impacts switching losses and EMI in high-frequency DC-DC topologies |
| VF @ 1.5 A | 1.0 V - Forward voltage drop at rated current; sets conduction loss and thermal dissipation (1.5 W typical) |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance; used to calculate max ambient temperature for 150°C TJ limit |
| IFSM | 50 A - Non-repetitive surge current (8.3 ms); supports inrush and fault-current tolerance |
| MSL | Level 1 - No floor life limitation; allows unlimited exposure to ambient conditions prior to reflow |

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, 1.0 A IF, 65 ns trr, TO-277 package | Higher voltage rating but lower current; requires layout change due to different footprint | Preferred when system needs >300 V standoff or space-constrained TO-277 mounting |

FAQ
What is the maximum junction temperature rating for HS2DAH?
The HS2DAH has a maximum junction temperature (TJ MAX) of +150°C, verified per AEC-Q101 thermal stress testing. This rating enables reliable operation in under-hood automotive environments where ambient temperatures reach +105°C, provided thermal design maintains junction temperature below 150°C using the specified RθJA of 80 °C/W. The HS2DAH datasheet confirms this limit applies across its full operating voltage range.
Is HS2DAH suitable for use in automotive lighting applications?
Yes, HS2DAH is explicitly qualified to AEC-Q101 and listed in the Applications section for car lighting. Its 200 V VRRM, 50 ns trr, and glass-passivated junction provide robust performance against load dump transients and thermal cycling in LED driver modules. The HS2DAH's DO-214AC package supports automated assembly in high-volume automotive lighting production lines.
What does the marking code 'HS2DAH' indicate on the device body?
The marking code 'HS2DAH' on the HS2DAH device corresponds directly to its part number and denotes the 200 V variant within the HS2xAH family. Per the ordering information table, 'D' specifies VRRM = 200 V, and the 'H' suffix indicates halogen-free construction compliant with IEC 61249-2-21. The cathode band identifies the cathode terminal.
How does HS2DAH compare to HS2FAH in terms of forward voltage and recovery time?
Both HS2DAH and HS2FAH share identical electrical specifications for VF (1.0 V at 1.5 A) and trr (50 ns), as confirmed in the Electrical Specifications table. The only difference is VRRM: HS2DAH is rated at 200 V, while HS2FAH is rated at 300 V. All other parameters-including IF, IFSM, RθJA, and packaging-are identical between the two devices.
Does HS2DAH require special handling during PCB assembly?
No, HS2DAH has Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions without baking or dry-pack requirements. Its DO-214AC (SMA) package uses matte tin-plated leads solderable per J-STD-002, supporting standard lead-free reflow profiles. The HS2DAH datasheet confirms compatibility with automated placement and standard SMT processes.
