Taiwan Semiconductor Corporation TSD2JAL

Overview

TSD2JAL from Taiwan Semiconductor is a 2A, 600V glass-passivated ESD-hardened rectifier diode in Thin SMA package, featuring 1.1V max forward voltage at 2A/25°C, ≤1µA reverse leakage at 25°C, and ≥10kV IEC 61000-4-2 contact-mode ESD immunity-used for polarity protection in industrial power supplies and DC input stages.

For engineers reviewing the TSD2JAL datasheet, TSD2JAL pinout, TSD2JAL application, or TSD2JAL equivalent, key selection criteria include its 600V V_RRM, 40A I_FSM surge rating, 15°C/W R_θJL, JESD201 Class 2 whisker resistance, and UL 94V-0 molding compound compliance.

Technical Context

The TSD2JAL is a single-die, unidirectional silicon rectifier with cathode-band polarity marking and glass-passivated junction for enhanced reliability under thermal cycling and humidity stress. Its 600V repetitive peak reverse voltage and 420V rms reverse voltage rating support use in 380VAC-derived DC bus applications.

Thermal performance is characterized with R_θJL = 15°C/W and R_θJA = 75°C/W on a 5mm × 5mm Cu pad PCB, enabling 2A continuous operation up to +125°C ambient when properly mounted. Junction temperature range spans −40°C to +175°C.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) specified for the TSD2JAL?

The TSD2JAL has a maximum repetitive peak reverse voltage (V_RRM) of 600 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2309). This rating applies under standard test conditions (T_A = 25°C) and defines the highest reverse voltage the device can block repeatedly without breakdown. The TSD2JAL is therefore suitable for rectifying 380VAC mains-derived supplies where peak line voltage reaches ~537V.

Does the TSD2JAL meet industry-standard ESD immunity requirements?

Yes, the TSD2JAL is certified to ≥10 kV contact discharge per IEC 61000-4-2 and ≥15 kV air discharge, as documented in the Immunity to Electrical Static Discharge section of its datasheet. It also achieves AEC-Q101-001 Human Body Model Class H3B (≥8 kV). These ratings are measured on the packaged device-not just the die-making the TSD2JAL suitable for use in systems requiring certified board-level ESD robustness without additional protection components.

What is the forward voltage drop (V_F) of the TSD2JAL at 2A and 25°C?

The TSD2JAL exhibits a maximum forward voltage drop (V_F) of 1.1 V at 2 A and 25°C, as specified in the Electrical Specifications table. At 1 A and 25°C, V_F is typically 0.89 V with a maximum of 1.1 V. This low conduction loss helps minimize power dissipation-critical for thermally constrained designs-and is achieved via optimized silicon geometry and glass passivation in the TSD2JAL.

Is the TSD2JAL compatible with lead-free reflow soldering processes?

Yes, the TSD2JAL features matte tin-plated leads that are fully compatible with lead-free reflow soldering per J-STD-002. Its moisture sensitivity level is rated at Level 1 (per J-STD-020), meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. The device's UL 94V-0 compliant molding compound also withstands peak reflow temperatures up to 260°C for 10 seconds, meeting IPC/JEDEC J-STD-020D.3 requirements.

What thermal resistance values are specified for the TSD2JAL in its Thin SMA package?

The TSD2JAL specifies R_θJL = 15°C/W (junction-to-lead), R_θJC = 15°C/W (junction-to-case), and R_θJA = 75°C/W (junction-to-ambient) when mounted on a 5 mm × 5 mm copper pad PCB, as stated in the Thermal Performance section. These values enable accurate thermal modeling: at 2 A continuous current and 25°C ambient, junction temperature rise is approximately 33°C above ambient (based on R_θJL and typical lead power dissipation), keeping T_J well within its −40°C to +175°C operating range.
