Product details
Overview
HS15JLW from Taiwan Semiconductor is a 1.5A, 600V high-efficiency surface-mount silicon rectifier diode in SOD-123W package, featuring 75 ns reverse recovery time, 1.31 V forward voltage at 1.5 A and 25°C, and 9 pF junction capacitance. It serves as a freewheeling or output rectifier in DC-DC converters and switching-mode inverters.
For engineers reviewing the HS15JLW datasheet, HS15JLW pinout, HS15JLW application, or HS15JLW equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, thermal resistance of 43 °C/W (junction-to-lead), low-profile SOD-123W footprint, and verified performance at 125°C junction temperature.
Technical Context
The HS15JLW is a single-die, glass-passivated PN junction rectifier optimized for high-voltage switching applications. Its 600 V VRRM, 40 A IFSM, and 75 ns trr support fast transient response in SMPS output stages and flyback snubbers.
Thermal design is enabled by RθJL = 43 °C/W and RθJA = 84 °C/W on a 5 mm × 5 mm Cu pad, with operation rated from –55°C to +150°C. The cathode band marking and matte tin-plated leads ensure reliable automated assembly per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input/output isolation in 48 V–400 V DC-DC systems |
| IF | 1.5 A continuous - suitable for medium-power converter outputs up to ~30 W |
| trr | 75 ns - enables efficient operation at 100–500 kHz switching frequencies |
| VF @ 1.5 A, 25°C | 1.31 V typical - contributes ~2.0 W conduction loss at full load |
| CJ | 9 pF - minimizes capacitive coupling and EMI in high-dv/dt nodes |
| RθJL | 43 °C/W - allows direct PCB heat sinking without external heatsink |
| IFSM | 40 A - withstands inrush and short-circuit surge events in power supplies |

Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24–48 V input, 5–12 V output flyback or forward converters. IC Role / Device Role / Timing Role: Unidirectional current path enabling energy transfer from transformer secondary to output capacitor. Use Value: 600 V rating accommodates reflected voltage spikes; 75 ns trr reduces switching losses versus slower general-purpose rectifiers. | Use Scenario: Freewheeling path across inductive loads (e.g., motor windings, relay coils) in half-bridge inverters. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when main switches turn off. Use Value: 40 A IFSM handles inductive kickback surges; 1.31 V VF limits conduction loss during extended freewheeling intervals. |
| AC-DC Adapter Secondary Rectifier | Industrial Power Supply Snubber Diode |
Use Scenario: Output rectification in compact wall adapters delivering 12–24 V/1.5 A for IoT gateways and PoE injectors. IC Role / Device Role / Timing Role: Converts transformer AC output to regulated DC, filtering ripple with bulk capacitor. Use Value: SOD-123W footprint fits tight layouts; 9 pF CJ suppresses high-frequency ringing at rectifier turn-off. | Use Scenario: Clamp diode in RCD snubber networks across MOSFETs in 3 kW industrial SMPS. IC Role / Device Role / Timing Role: Absorbs voltage overshoot during MOSFET turn-off by conducting transient energy into RC network. Use Value: 600 V VRRM ensures margin against 400 V bus transients; glass passivation improves snubber reliability over 10-year life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L60S | 600 V VRRM, 1.1 A IF, 50 ns trr, DO-214AC package | Lower current rating; faster recovery but requires larger footprint | Select if <1.1 A average current suffices and faster trr is prioritized over size |
| ON Semi MUR160 | 600 V VRRM, 1.0 A IF, 75 ns trr, DO-41 through-hole | Through-hole mounting; lower current and no SMT compatibility | Select only for legacy through-hole designs where rework to SMT is not feasible |
Compared with STTH1L60S and MUR160, the HS15JLW uniquely delivers 1.5 A current handling in the ultra-compact SOD-123W package while maintaining 75 ns recovery - optimizing power density and thermal performance in space-constrained SMPS.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the HS15JLW?
The HS15JLW has a maximum repetitive peak reverse voltage (VRRM) of 600 V, as specified in the absolute maximum ratings table. This rating is confirmed across all official documentation and applies under standard test conditions (TA = 25°C). The 600 V value distinguishes HS15JLW from other variants in the HS15xLW series such as HS15DLW (200 V) and HS15MLW (1000 V). Designers must ensure system transient voltages remain below this limit with appropriate safety margin.
Does the HS15JLW support automated SMT placement?
Yes, the HS15JLW supports automated surface-mount placement. Its SOD-123W package features matte tin-plated leads compliant with J-STD-002 solderability standards, and it carries moisture sensitivity level 1 per J-STD-020 - meaning it can be used directly from dry pack without baking. The low-profile, symmetrical geometry and cathode band marking further enhance machine vision recognition and placement accuracy in high-volume manufacturing.
What is the forward voltage (VF) of the HS15JLW at 1.5 A and 125°C?
At 1.5 A forward current and 125°C junction temperature, the HS15JLW exhibits a typical forward voltage of 1.09 V and a maximum of 1.30 V, as documented in the electrical specifications table. This elevated temperature performance is critical for thermal design validation, confirming that conduction losses remain manageable even under worst-case ambient conditions. The HS15JLW's VF increases less than 0.25 V from 25°C to 125°C, indicating stable silicon characteristics.
Is the HS15JLW halogen-free and RoHS compliant?
Yes, the HS15JLW is both halogen-free in accordance with IEC 61249-2-21 and RoHS compliant, as explicitly stated in the FEATURES section of the official datasheet. These compliance attributes are verified for the SOD-123W package construction, including molding compound and lead finish. No exemptions apply, and full declaration documentation is available upon request for end-product regulatory submissions.
What is the junction-to-lead thermal resistance (RθJL) of the HS15JLW?
The HS15JLW has a typical junction-to-lead thermal resistance (RθJL) of 43 °C/W, measured with the device mounted on a 5 mm × 5 mm copper pad per JEDEC standards. This parameter enables accurate thermal modeling of PCB-level heat dissipation without requiring external heatsinks. It is lower than the junction-to-ambient value (84 °C/W), confirming that thermal transfer through the leads dominates over convection/radiation in typical layout configurations.
