Product details
Overview
HS2JALH from Taiwan Semiconductor is a 2 A, 600 V glass-passivated surface-mount rectifier in Thin SMA package, featuring 1.10 V forward voltage at 2 A / 25°C, 75 ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC/DC converters where high efficiency and thermal robustness are required.
For engineers reviewing the HS2JALH datasheet, HS2JALH pinout, HS2JALH application, or HS2JALH equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, 17 pF junction capacitance at 1 MHz/4 V, 150°C maximum junction temperature, and compatibility with automated SMT placement on standard PCB layouts.
Technical Context
The HS2JALH is a single-die, unidirectional silicon rectifier optimized for fast switching and low conduction loss in medium-voltage power conversion stages. Its glass-passivated junction ensures stable leakage performance across temperature, while the Thin SMA package enables compact board layout with J-STD-020 Level 1 moisture sensitivity.
Designed for operation up to 150°C junction temperature, it delivers 1.10 V forward drop at rated 2 A load and 25°C, dropping to 0.92 V at 125°C - supporting thermally demanding environments without derating penalties typical of higher-VF alternatives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rails up to 420 VRMS in AC-DC front-ends or 600 V bus clamping in industrial DC/DC converters |
| IF | 2 A continuous - sufficient for mid-power auxiliary supplies or gate-drive snubbers in 1–3 kW systems |
| trr | 75 ns - enables operation at switching frequencies up to ~500 kHz with minimal turn-off loss in hard-switched topologies |
| CJ | 17 pF at 1 MHz / 4 V - reduces capacitive coupling noise in high-dv/dt gate drive or snubber circuits |
| RθJA | 53 °C/W - allows 2 A operation on standard 5 mm × 5 mm Cu pad without forced air or heatsink in ambient ≤50°C |
| IFSM | 60 A (8.3 ms) - withstands inrush or fault currents in automotive load-dump or motor-control freewheeling paths |
Pinout & Package
Package: Thin SMA - low-profile surface-mount package with matte tin-plated leads, UL 94V-0 molding compound, and cathode band polarity marking. Weight: 0.029 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to lower-potential node (e.g., switch node in buck converter or motor winding return) |
| Cathode | Current exit terminal during forward conduction; marked by band | Connected to higher-potential rail (e.g., output capacitor positive or supply rail in freewheeling path) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control modules and ADAS power supplies |
| Glass-passivated junction | Ensures <1 µA reverse leakage at 25°C and <80 µA at 125°C - critical for low-power standby and precision snubbing |
| Low profile Thin SMA | Enables stacking with adjacent components in space-constrained modules such as OBCs and DC-DC bricks |
| J-STD-020 Level 1 moisture sensitivity | Eliminates bake requirements before reflow - compatible with standard SMT assembly lines without process modification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same 2 A / 600 V rating; TO-220AC package; 65 ns trr; 1.15 V VF @ 2 A | Through-hole mounting; higher RθJA (~70 °C/W); unsuitable for dense SMT layouts | Prefer HS2JALH for space-constrained SMT designs; STTH2R06 only where through-hole mechanical retention is required. |
| ON Semi MUR260 | 2 A / 600 V; DO-201AD package; 75 ns trr; 1.10 V VF @ 2 A; no AEC-Q101 qualification | Larger footprint; not qualified for automotive; higher RθJA (~65 °C/W) | Acceptable for industrial non-automotive use; HS2JALH preferred when AEC-Q101 compliance or thinner profile is mandatory. |
Compared with STTH2R06 and MUR260, the HS2JALH provides identical voltage/current ratings but adds AEC-Q101 qualification, Thin SMA form factor, and superior thermal resistance - making it the optimal choice for automotive and high-density power modules where reliability and board space are critical.

FAQ
What is the maximum junction temperature rating for HS2JALH?
The HS2JALH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows continuous operation in under-hood automotive environments or enclosed industrial enclosures without thermal derating below full 2 A current, provided PCB thermal design meets the 5 mm × 5 mm copper pad requirement specified in the thermal performance note.
Is HS2JALH suitable for automotive applications?
Yes, HS2JALH is AEC-Q101 qualified and explicitly listed in the Applications section for automotive use. Its glass-passivated junction, 150°C TJ rating, and JESD201 Class 2 whisker resistance make it appropriate for engine control units, body electronics, and ADAS power supplies where reliability under thermal cycling and vibration is mandatory.
What is the forward voltage of HS2JALH at 2 A and 125°C?
The forward voltage of HS2JALH is 0.92 V (typical) and 1.10 V (maximum) at 2 A and 125°C, as specified in the Electrical Specifications table. This reduced VF at elevated temperature improves system efficiency in thermally stressed conditions compared to diodes with positive VF temperature coefficients.
Does HS2JALH have a defined reverse recovery time?
Yes, HS2JALH has a specified reverse recovery time (trr) of 75 ns maximum, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table and applies to all variants from HS2JALH through HS2MALH, enabling predictable switching loss calculation in high-frequency power topologies.
What package type does HS2JALH use, and what are its key mechanical features?
HS2JALH uses the Thin SMA package: a low-profile surface-mount outline with matte tin-plated leads, UL 94V-0 compliant molding compound, cathode band polarity marking, and J-STD-020 Level 1 moisture sensitivity. Its 0.029 g weight and compact dimensions support high-density PCB layouts and automated placement without special handling.
