Product details

Overview

HS2JAL from Taiwan Semiconductor is a 600 V, 2 A glass-passivated surface-mount fast recovery rectifier in Thin SMA package, with 75 ns reverse recovery time, 1.10 V forward voltage at 2 A/25°C, and 17 pF junction capacitance - deployed in DC-DC converters and switching inverters requiring high efficiency and low profile.

For engineers reviewing the HS2JAL datasheet, HS2JAL pinout, HS2JAL application, or HS2JAL equivalent, key selection criteria include peak reverse voltage (600 V), thermal resistance (R_θJL = 17 °C/W), junction temperature range (–55 to +150 °C), and moisture sensitivity level (MSL 1).

Technical Context

This single-die, unidirectional fast recovery rectifier uses a glass-passivated PN junction for stable high-voltage blocking and low leakage. Its 75 ns trr and 17 pF CJ support high-frequency switching up to several hundred kHz in SMPS topologies.

Designed for automated SMT placement, the Thin SMA package features matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and polarity indicated by cathode band - enabling reliable reflow soldering without whisker risk (JESD 201 Class 2).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input stages of 400 V AC-derived DC bus or 300 V DC systems with safety margin
I_F	2 A continuous - suitable for medium-power output rectification in 25–50 W SMPS
t_rr	75 ns - enables efficient operation in 100–500 kHz switching converters with reduced switching loss
V_F @ 2A/25°C	1.10 V max - contributes to <1.5 W conduction loss at full load, aiding thermal management
C_J	17 pF - minimizes capacitive coupling noise and EMI in high-dv/dt gate-drive or snubber circuits
R_θJL	17 °C/W - allows direct PCB copper pad heat sinking for sustained 2 A operation without heatsink
I_FSM (8.3 ms)	60 A - withstands typical inrush and transient surge events in offline power supplies

IC Role / Device Role / Timing Role: Unidirectional current valve converting high-frequency AC from transformer to regulated DC output. Use Value: 600 V V_RRM accommodates reflected voltage spikes; 1.10 V V_F limits conduction loss to <2.2 W at full load.

Use Value: 600 V V_RRM provides >80 % safety margin over peak line voltage; MSL 1 simplifies manufacturing flow.	Use Scenario: Clamp diode in RCD snubber network across MOSFETs in industrial 3-phase inverters operating at 400–690 V bus.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R06	600 V, 2 A, 60 ns trr, TO-220AC package, higher R_θJA (50 °C/W)	Requires heatsink above ~1 A; unsuitable for ultra-thin designs	Prefer HS2JAL for SMT density and thermal performance on PCB; STTH2R06 only where through-hole mounting or higher surge tolerance needed
ES2J	600 V, 2 A, 35 ns trr, SMA package, but VF = 1.7 V @ 2 A/25°C	Higher conduction loss; lower C_J (12 pF)	Choose ES2J when fastest recovery is critical and thermal headroom exists; HS2JAL preferred for balanced VF/trr trade-off in general-purpose SMPS

Compared with STTH2R06 and ES2J, HS2JAL delivers optimal balance of low forward drop (1.10 V), moderate recovery speed (75 ns), and superior thermal resistance (17 °C/W) in a low-profile SMT package - making it ideal for space- and thermally constrained 2 A power conversion stages.

FAQ

What is the maximum junction temperature rating for HS2JAL?

The HS2JAL has a maximum junction temperature (T_J) of +150 °C and a minimum of –55 °C, allowing operation in industrial environments with ambient temperatures up to +105 °C when mounted on a 5 mm × 5 mm copper pad. This rating is confirmed in the Absolute Maximum Ratings table of the official TSC C2103 datasheet for HS2JAL.

Does HS2JAL have a specified reverse recovery time, and how is it measured?

Yes, HS2JAL has a reverse recovery time (t_rr) of 75 ns maximum, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, as stated in the Electrical Specifications section of the TSC C2103 datasheet. This value applies across the full operating temperature range and supports high-frequency switching designs.

What is the forward voltage of HS2JAL at 2 A and 125 °C?

The forward voltage of HS2JAL is 0.92 V typical and 1.10 V maximum at 2 A and 125 °C, per the Electrical Specifications table in the TSC C2103 datasheet. This lower V_F at elevated temperature improves thermal stability compared to silicon rectifiers with positive temperature coefficients above 100 °C.

Is HS2JAL compatible with lead-free reflow soldering processes?

Yes, HS2JAL is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its MSL 1 rating per J-STD-020 means it can be stored indefinitely and processed using standard JEDEC-compliant reflow profiles without baking.

What does the marking code 'HS2JAL' indicate on the device body?

The marking code 'HS2JAL' on the device body directly identifies the part as the 600 V variant of the HS2xAL family. Per the Ordering Information section of the TSC C2103 datasheet, 'J' corresponds to 600 V V_RRM, confirming this is the exact HS2JAL device - not a generic family placeholder.
