Product details
Overview
TSD2JALH from Taiwan Semiconductor is a 2A, 600V glass-passivated ESD-hardened rectifier diode in Thin SMA package, featuring 40A surge current rating, 15°C/W junction-to-lead thermal resistance, and AEC-Q101 qualification for automotive-grade reliability. It serves as a polarity protection and general-purpose rectification device in DC power rails of engine control units and body electronics.
For engineers reviewing the TSD2JALH datasheet, TSD2JALH pinout, TSD2JALH application, or TSD2JALH equivalent, key selection criteria include its 600V VRRM, 0.94V forward voltage at 2A/25°C, -40°C to +175°C operating junction temperature, ESD immunity ≥10kV (IEC 61000-4-2 contact), and Thin SMA mechanical compatibility with automated SMT placement.
Technical Context
This single-die standard recovery rectifier uses glass passivation for stable junction integrity under thermal cycling and humidity stress. Its 15°C/W RθJL enables direct PCB heat conduction via copper pad mounting, supporting continuous 2A operation up to 125°C ambient when derated per curve data.
The device meets AEC-Q101 stress test requirements including HBM ESD ≥8kV (Class H3B), IEC 61000-4-2 contact discharge ≥10kV, and ISO 10605 contact mode ≥10kV - confirming robustness against assembly and field electrostatic events without external protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking capability in 48V–60V automotive systems. |
| IF | 2 A - Continuous forward current rating; supports steady-state power rail protection in ECUs and lighting modules. |
| IFSM | 40 A - Non-repetitive surge current (8.3ms); handles load dump transients without failure. |
| VF @ 2A, 25°C | 0.94 V max - Low conduction loss reduces power dissipation and thermal stress in compact layouts. |
| RθJL | 15 °C/W - Enables efficient heat transfer to PCB copper; allows 2A operation with minimal heatsinking. |
| TJ max | +175 °C - High junction temperature rating supports under-hood deployment without derating penalties. |
| ESD Rating | ≥10 kV IEC 61000-4-2 contact - Eliminates need for discrete TVS in many board-level ESD protection schemes. |
Pinout & Package
Thin SMA package: surface-mount, single-anode/single-cathode configuration with cathode band marking; dimensions per JEDEC DO-221AC (5.35 × 4.40 × 2.10 mm); matte tin-plated leads, MSL Level 1, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to positive side of input source during conduction; must withstand full surge current path. |
| Cathode | Forward current exit / reverse voltage blocking terminal | Marked by band; ties to system ground or return path; blocks 600V reverse potential during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use across temperature, humidity, and mechanical shock profiles - eliminates qualification overhead for Tier 1 suppliers. |
| Glass passivated junction | Prevents moisture ingress and ion migration at high temperature/humidity - ensures long-term parametric stability in under-hood environments. |
| Low VF (0.94V @ 2A) | Reduces conduction loss by ~15% vs. legacy 1N5822-class diodes - lowers thermal footprint in space-constrained modules. |
| ESD immunity ≥10kV (IEC contact) | Withstands ESD events during handling and assembly without screening or retest - improves manufacturing yield. |
| Thin SMA package | Enables high-density layout with 4.4mm × 5.35mm footprint - compatible with standard SMA pick-and-place nozzles and reflow profiles. |
Applications
| Engine Control Unit Power Input | LED Headlamp Polarity Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS2L60 | 60V VRRM, 2A, Schottky; lower VF (0.55V) but limited to ≤125°C TJ | Not suitable for 48V+ systems or under-hood ambient >105°C | Select only for low-voltage, low-temperature consumer-grade designs. |
| SB260-E3/54 | 60V VRRM, 2A, Schottky; 125°C max TJ, no AEC-Q101 or ESD rating | Lacks automotive qualification and ESD hardening - requires external TVS for IEC 61000-4-2 compliance | Acceptable for cost-sensitive industrial non-automotive applications only. |
Compared with STPS2L60 and SB260-E3/54, the TSD2JALH delivers higher voltage blocking (600V), extended temperature range (+175°C), and integrated ESD protection - making it uniquely suited for automotive power input stages where reliability and system-level ESD immunity are mandatory.

FAQ
What is the maximum repetitive peak reverse voltage rating for TSD2JALH?
The TSD2JALH has a VRRM rating of 600 V, verified per JEDEC JESD201 and AEC-Q101 stress testing. This value is specified at TA = 25°C and remains valid up to +125°C ambient when derated per the forward current derating curve in the official TSC datasheet revision B2312. The TSD2JALH maintains reliable blocking behavior without avalanche conduction under this voltage.
Is TSD2JALH qualified for automotive applications?
Yes, the TSD2JALH is AEC-Q101 qualified per test condition H3B (HBM ≥8kV), with full validation across temperature cycling, humidity bias, and mechanical shock. It is explicitly intended for automotive power input protection in ECUs, BCMs, and lighting modules - confirmed by Taiwan Semiconductor's product family documentation and qualification reports referenced in version B2312.
What is the forward voltage drop of TSD2JALH at 2A and 25°C?
The TSD2JALH exhibits a maximum forward voltage (VF) of 1.1 V at IF = 2 A and TJ = 25°C, with typical value 0.94 V. This is measured under pulse conditions (PW = 0.3 ms) and reflects conduction loss in real-world 2A DC applications such as polarity protection in 12V/48V automotive subsystems.
Does TSD2JALH have ESD protection built-in?
Yes, the TSD2JALH integrates ESD hardening per multiple standards: ≥8kV HBM (AEC-Q101-001), ≥10kV IEC 61000-4-2 contact discharge, ≥15kV air discharge, and ≥10kV ISO 10605 contact mode. These ratings are measured on the packaged device and do not require external TVS diodes for basic board-level ESD compliance in automotive modules.
What package type does TSD2JALH use and what are its key mechanical features?
The TSD2JALH uses the Thin SMA package per JEDEC DO-221AC (variation AC). Key features include 5.35 mm × 4.40 mm × 2.10 mm outline, matte tin-plated leads compliant with J-STD-002, MSL Level 1 rating, UL 94V-0 flammability, and cathode band polarity marking - all verified in TSC's mechanical drawings HQ2SD07-TSMA-074 REV A.
