Product details
Overview
TSD3JALH from Taiwan Semiconductor is a 600V, 3A glass-passivated ESD-hardened rectifier diode in Thin SMA package, featuring 50A surge rating, 175°C max junction temperature, and AEC-Q101 qualification - ideal for automotive polarity protection and industrial power supply input stages.
For engineers reviewing the TSD3JALH datasheet, TSD3JALH pinout, TSD3JALH application, or TSD3JALH equivalent, key selection criteria include its 600V VRRM, 0.96V forward voltage at 3A/25°C, 15°C/W junction-to-lead thermal resistance, and ≥15kV IEC 61000-4-2 air-discharge ESD immunity.
Technical Context
This single-die standard recovery rectifier uses glass passivation to ensure stable reverse leakage (<1µA @ 25°C) and high-temperature operation up to 175°C. Its Thin SMA package (JEDEC DO-221AC) enables automated placement while maintaining low thermal resistance (RθJL = 15°C/W).
The device meets AEC-Q101 stress requirements including HBM ≥8kV (Class H3B), ISO 10605 ≥15kV (Contact), and IEC 61000-4-2 ≥15kV (Air). Reverse recovery behavior is not specified; it is not a fast- or ultrafast-recovery diode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage; defines safe blocking capability in DC-link or AC-input applications |
| IF | 3 A - continuous forward current rating at TA=25°C; derates linearly above 25°C ambient |
| IFSM | 50 A - non-repetitive surge current (8.3ms sine); supports inrush current handling in power supplies |
| VF @ 3A, 25°C | 0.96 V - forward voltage drop; determines conduction loss and thermal load under full-rated DC current |
| RθJL | 15 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pad heat sinking without heatsink |
| ESD (IEC 61000-4-2 Air) | ≥15 kV - immunity level; eliminates need for external TVS in many automotive body electronics designs |
| TJ max | 175 °C - maximum operating junction temperature; supports under-hood automotive environments |
Pinout & Package
Thin SMA package (JEDEC DO-221AC variation), surface-mount, cathode-indicated by band. Dimensions: 4.40 × 2.70 × 1.20 mm (L × W × H), matte tin-plated leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or return path) in polarity protection configurations |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; connected to input rail in reverse-polarity protection; carries full system voltage when reverse-biased |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements - enables deployment in engine control, lighting, and body modules without additional qualification |
| Glass passivated junction | Enhances long-term reliability and humidity resistance vs. epoxy-passivated alternatives - critical for under-hood and outdoor industrial enclosures |
| High ESD immunity (≥15kV air) | Reduces risk of field failure during handling or system-level ESD events - lowers warranty cost in automotive assembly lines |
| Thin SMA package | Enables high-density PCB layouts and compatibility with standard SMT reflow profiles - supports automated manufacturing at scale |
| Low VF (0.96V @ 3A) | Minimizes conduction loss and self-heating at rated current - extends thermal margin in compact power supplies |
Applications
| Automotive Polarity Protection | Industrial DC Power Input |
|---|---|
Use Scenario: Protecting vehicle infotainment ECUs against battery reverse connection during service or jump-start events. IC Role / Device Role / Timing Role: Standalone unidirectional blocking element placed in series with main power rail. Use Value: Withstands 600V reverse transients and delivers <1µA leakage at 125°C - ensures zero false shutdowns in hot under-hood conditions. | Use Scenario: Input rectification stage in DIN-rail mounted 24V/48V industrial power supplies. IC Role / Device Role / Timing Role: Main AC-to-DC conversion diode in bridge or single-phase configuration. Use Value: 50A surge rating handles capacitor inrush; 175°C TJ max allows operation in sealed enclosures without forced airflow. |

Use Scenario: Reverse-voltage clamp on constant-current LED driver inputs exposed to field wiring errors. IC Role / Device Role / Timing Role: Polarity guard before bulk capacitance and switching controller. Use Value: 0.96V forward drop minimizes power loss across protection path; AEC-Q101 grade supports commercial + industrial LED fixtures. | Use Scenario: Supply rail protection on brushed DC motor control boards subject to back-EMF spikes and ESD from operator contact. IC Role / Device Role / Timing Role: Clamp diode across H-bridge supply rails to absorb inductive kickback. Use Value: ≥15kV air-discharge ESD rating prevents latch-up or degradation during bench testing and field maintenance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V, 3A, TO-220AC package; faster recovery (trr = 50ns), higher VF (1.15V @ 3A) | Requires heatsink mounting; unsuitable for space-constrained SMT-only designs | Choose when fast recovery is required and board area permits through-hole or heatsinked layout |
| SS36-E3/57T | 60V, 3A Schottky; VF = 0.7V @ 3A but VRRM too low for 600V systems | Not suitable for line-voltage or automotive battery applications due to 60V rating | Only viable in low-voltage DC-DC input stages where reverse voltage ≤60V |
Compared with STTH3L06S and SS36-E3/57T, the TSD3JALH uniquely combines 600V blocking, SMT Thin SMA footprint, AEC-Q101 qualification, and ≥15kV ESD immunity - making it the only drop-in option for space-limited, high-reliability automotive and industrial rectification where both voltage rating and robustness are mandatory.

FAQ
What is the maximum junction temperature rating for TSD3JALH?
The TSD3JALH has a maximum junction temperature (TJ) of +175°C, verified per AEC-Q101 thermal stress testing. This allows reliable operation in under-hood automotive environments and sealed industrial enclosures without active cooling. The device maintains <1µA reverse leakage at 125°C, confirming thermal stability across its full rated range.
Is TSD3JALH pin-compatible with TSD3GALH?
Yes, TSD3JALH and TSD3GALH share identical Thin SMA package dimensions, pinout, and marking layout - differing only in VRRM (600V vs. 400V) and marking code (D3JAL vs. D3GAL). Both use the same anode/cathode terminal configuration and solder pad footprint, enabling direct voltage-rating upgrades without PCB revision.
Does TSD3JALH have a specified reverse recovery time (trr)?
No, reverse recovery time (trr) is not specified in the official TSD3JALH datasheet. The device is characterized as a standard recovery rectifier - optimized for ESD robustness and thermal performance rather than fast switching. For trr-critical applications, consult alternative ultrafast or soft-recovery diodes.
What ESD standards does TSD3JALH meet, and at what levels?
TSD3JALH meets AEC-Q101-001 (HBM ≥8kV, Class H3B), IEC 61000-4-2 (≥15kV air discharge, ≥10kV contact), and ISO 10605 (≥15kV contact mode). These ratings are measured per standardized test conditions and confirm suitability for automotive assembly lines and industrial field-deployed equipment.
Can TSD3JALH be used in place of a Schottky diode in low-VF applications?
TSD3JALH has a typical VF of 0.96V at 3A/25°C - higher than most Schottky diodes (e.g., 0.7V). While it offers superior 600V blocking and ESD immunity, it is not a Schottky device and exhibits higher reverse leakage at elevated temperatures. Use only where 600V rating and ruggedness outweigh ultra-low VF requirements.
