Product details
Overview
TSD1JLWH from Taiwan Semiconductor is a 600V, 1A glass-passivated ESD-hardened surface-mount rectifier in SOD-123W package, featuring 30A surge rating, 0.90V forward voltage at 1A/25°C, and AEC-Q101 qualification for automotive polarity protection circuits.
For engineers reviewing the TSD1JLWH datasheet, TSD1JLWH pinout, TSD1JLWH application, or TSD1JLWH equivalent, key selection criteria include its 600V repetitive peak reverse voltage, 175°C maximum junction temperature, 10kV IEC 61000-4-2 contact-mode ESD immunity, and SOD-123W mechanical compatibility with automated placement.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-reliability DC polarity protection and general-purpose AC/DC input stage clamping. Its glass-passivated junction ensures stable leakage performance across -40°C to +175°C operating range, while the SOD-123W package delivers 15°C/W junction-to-lead thermal resistance on standard PCB pads.
The TSD1JLWH meets AEC-Q101 stress test requirements including HBM ≥8kV (Class H3B), ISO 10605 ≥10kV (Class L3), and IEC 61000-4-2 ≥15kV air discharge - confirming suitability for harsh automotive environments where electrostatic robustness is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines safe operating margin in 48V–400V DC bus protection. |
| IF | 1 A continuous - Rated average forward current under defined thermal conditions; supports compact layout in space-constrained modules. |
| IFSM | 30 A (8.3ms) - Peak non-repetitive surge current handling; enables robustness against inrush and load dump transients. |
| VF @ 1A/25°C | 0.90 V max - Forward voltage drop determining conduction loss and self-heating at full rated current. |
| TJ max | +175 °C - Maximum junction temperature enabling operation in under-hood automotive locations without derating. |
| ESD immunity | ≥10 kV contact (IEC 61000-4-2) - Confirmed immunity level allowing direct integration into exposed interfaces without external ESD protection. |
| RθJL | 15 °C/W - Junction-to-lead thermal resistance measured on 5mm × 5mm Cu pad; enables accurate thermal modeling for board-level reliability. |
Pinout & Package
SOD-123W surface-mount plastic package with matte tin-plated leads, moisture sensitivity level 1 (J-STD-020), UL 94V-0 molding compound, and cathode band polarity indicator. Weight: 0.015 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of protected circuit; must be routed with adequate copper area for thermal dissipation. |
| Cathode | Forward current exit / reverse voltage blocking terminal | Marked by visible band; connects to higher-potential rail; determines direction of polarity protection function. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per JESD47. |
| 600V VRRM rating | Provides 50% voltage margin above 400V nominal DC bus systems, reducing risk of reverse breakdown during transients. |
| 175°C TJ max | Enables uninterrupted operation in engine control units and power distribution modules without thermal shutdown. |
| 10kV IEC 61000-4-2 contact ESD | Eliminates need for discrete TVS diodes in many CAN/LIN interface protection designs, simplifying BOM. |
| Low VF (0.90V @ 1A) | Reduces power loss to ≤0.9W at full load, minimizing thermal stress on adjacent components and PCB traces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | 600V, 1A, TO-277A package; VF = 1.05V @ 1A; RθJA = 90°C/W; not AEC-Q101 qualified | Larger footprint; higher thermal resistance; suitable for industrial but not automotive qualification paths | Select when cost-driven industrial design tolerates larger size and lacks automotive compliance requirements |
| ES1J | 600V, 1A, DO-214AA package; VF = 1.7V @ 1A; ESD rating not specified; RθJA = 65°C/W | Higher conduction loss; no documented ESD immunity; legacy through-hole alternative | Choose only for legacy board refresh where SOD-123W rework is impractical and ESD robustness is secondary |
Compared with STTH1R06U and ES1J, the TSD1JLWH provides superior ESD immunity (≥10kV), lower forward voltage (0.90V vs. ≥1.05V), and AEC-Q101 qualification - making it the preferred choice for new automotive designs requiring compact, robust, and compliant polarity protection.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the TSD1JLWH?
The TSD1JLWH has a VRRM of 600 V, verified per JEDEC test conditions. This rating ensures reliable blocking capability in 400V-class DC systems with transient margin. The value is explicitly assigned to TSD1JLWH in the Absolute Maximum Ratings table and distinguishes it from the 400V-rated TSD1GLWH variant.
Is the TSD1JLWH qualified for automotive applications?
Yes, the TSD1JLWH is AEC-Q101 qualified, having passed all required stress tests including HBM ESD ≥8kV (Class H3B), temperature cycling, and high-temperature reverse bias. This qualification is documented in the Features section and confirmed in the Immunity to Electrical Static Discharge table.
What package type does the TSD1JLWH use and what are its key mechanical properties?
The TSD1JLWH uses the SOD-123W package: a surface-mount outline with 2.90 mm × 1.40 mm body dimensions, matte tin-plated leads, UL 94V-0 flammability rating, and cathode band polarity marking. Its weight is 0.015 g, and it meets JESD201 Class 2 whisker resistance.
What is the forward voltage (VF) of the TSD1JLWH at 1A and 25°C?
The TSD1JLWH has a maximum forward voltage of 1.10 V and a typical value of 0.90 V at IF = 1.0 A and TJ = 25°C, as specified in the Electrical Specifications table. Pulse testing conditions (PW = 0.3 ms) apply, and the value is confirmed for the exact TSD1JLWH variant.
Does the TSD1JLWH have documented ESD immunity, and to which standards?
Yes, the TSD1JLWH has documented ESD immunity per three standards: AEC-Q101-001 (HBM ≥8kV), IEC 61000-4-2 (contact ≥10kV, air ≥15kV), and ISO 10605 (contact ≥10kV). These values are tabulated in the Immunity to Electrical Static Discharge section and apply specifically to TSD1JLWH.
