Product details

Overview

TSD1JLW from Taiwan Semiconductor is a 1 A, 600 V repetitive peak reverse voltage (V_RRM) glass-passivated ESD-hardened rectifier diode in SOD-123W package, featuring 30 A surge current capability, 15 °C/W junction-to-lead thermal resistance, and ≥10 kV IEC 61000-4-2 contact-mode ESD immunity - used for polarity protection in industrial power supplies and DC input stages.

For engineers reviewing the TSD1JLW datasheet, TSD1JLW pinout, TSD1JLW application, or TSD1JLW equivalent, key selection criteria include its 600 V V_RRM, 1.10 V max forward voltage at 1.0 A/25°C, SOD-123W footprint compatibility, -40°C to +175°C operating range, and AEC-Q101-001 H3B-class ESD robustness.

Technical Context

This device is a single-die, unidirectional silicon rectifier with glass-passivated junction for enhanced reliability under thermal cycling and humidity stress. Its 600 V V_RRM rating enables use in higher-voltage DC bus conditioning where legacy 400 V parts like TSD1GLW are insufficient.

The SOD-123W package delivers 15 °C/W R_θJL and supports automated placement per J-STD-002 solderability standards. ESD immunity meets AEC-Q101-001 H3B (≥8 kV HBM) and IEC 61000-4-2 (≥10 kV contact, ≥15 kV air), confirming suitability for harsh-environment automotive and industrial interfaces.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports DC input rails up to 420 V RMS or 600 V transient spikes without breakdown
I_F	1 A continuous - rated for steady-state operation in low-power AC/DC front-end and battery-input protection
I_FSM	30 A (8.3 ms) - withstands inrush surges from capacitive loads or hot-plug events
V_F max	1.10 V @ 1.0 A, 25°C - limits conduction loss to ≤1.1 W at full rated current
T_J max	+175°C - enables operation in sealed enclosures or near heat-generating components
R_θJL	15 °C/W - allows direct PCB copper pad thermal coupling for passive cooling without heatsink
ESD (IEC 61000-4-2)	≥10 kV contact - eliminates need for external TVS in many board-level ESD protection schemes

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STPS1H60S	600 V V_RRM, 1 A I_F, but Schottky architecture → lower V_F (~0.65 V) yet higher leakage (≤50 µA @ 25°C)	Not suitable where low IR is critical (e.g., battery backup paths); better for efficiency-sensitive low-V_F apps	Select STPS1H60S only if forward-loss reduction outweighs leakage sensitivity and ESD immunity requirements
1N4007G	1 A/1000 V, but DO-41 through-hole, no ESD rating, 3 A I_FSM, 100 °C T_J max	Requires PCB rework for SMT transition; unsuitable for automotive or high-reliability industrial use	Choose 1N4007G only for cost-driven, non-automotive, non-ESD-critical prototyping with through-hole assembly

Compared with STPS1H60S and 1N4007G, TSD1JLW uniquely combines 600 V rating, SOD-123W SMT compatibility, AEC-Q101 ESD robustness, and +175°C operation - making it the only option qualified for automotive-grade DC input protection without layout or reliability trade-offs.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) specified for TSD1JLW?

The TSD1JLW 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 distinguishes it from the TSD1GLW variant (400 V) and defines its use in higher-voltage DC input circuits. The 600 V rating is tested and guaranteed under standard conditions per JEDEC guidelines.

Does TSD1JLW meet AEC-Q101 reliability standards?

Yes, TSD1JLW is qualified to AEC-Q101-001 under Human Body Model (HBM) testing, achieving Class H3B with ≥8 kV ESD immunity. This qualification is explicitly stated in the Immunity to Electrical Static Discharge section of the datasheet. TSD1JLW's AEC-Q101 compliance supports its use in automotive body electronics and industrial control units requiring certified component reliability.

What is the forward voltage (V_F) of TSD1JLW at 1.0 A and 25°C?

The forward voltage (V_F) of TSD1JLW is specified as a maximum of 1.10 V at 1.0 A and 25°C, with a typical value of 0.90 V under the same conditions. This parameter is listed in the Electrical Specifications table and reflects conduction loss under nominal operating conditions. Pulse test conditions (PW = 0.3 ms) apply, consistent with industry-standard diode characterization methods.

Is TSD1JLW compatible with lead-free reflow soldering processes?

Yes, TSD1JLW features matte tin-plated leads compliant with J-STD-002 solderability requirements and is rated for lead-free reflow. Its moisture sensitivity level is MSL Level 1 (per J-STD-020), meaning it can be stored indefinitely at ambient conditions without baking prior to assembly. The SOD-123W package is fully compatible with standard IPC-7095-compliant SMT processes.

What thermal resistance values are specified for TSD1JLW?

TSD1JLW 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 test board. These values are published in the Thermal Performance section and enable accurate thermal modeling for PCB-level heat dissipation without external heatsinks.
