Product details
Overview
TSD3JAL from Taiwan Semiconductor is a 600V, 3A glass-passivated ESD-hardened rectifier diode in Thin SMA package, featuring 15°C/W junction-to-lead thermal resistance, ≤1.1V forward voltage at 3A/25°C, and ≥10kV IEC 61000-4-2 contact-mode ESD immunity - deployed in automotive body control modules for reverse-polarity protection.
For engineers reviewing the TSD3JAL datasheet, TSD3JAL pinout, TSD3JAL application, or TSD3JAL equivalent, key selection criteria include its 600V VRRM, 50A IFSM, JESD201 Class 2 whisker resistance, UL 94V-0 molding compound, and cathode-band polarity marking on the Thin SMA case.
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 175°C and exhibits 18pF junction capacitance at 1MHz/4V. Its thermal design enables sustained 3A average forward current on a 5mm × 5mm copper pad PCB layout.
The device meets AEC-Q101-001 H3B-class human-body-model ESD (≥8kV) and exceeds IEC 61000-4-2 air-discharge requirements (≥15kV), with reverse leakage limited to 1µA at 25°C and 6µA at 125°C under rated VR.
Key Specifications

| VRRM | 600 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in 48V+ automotive power rails |
| IF | 3 A - Continuous average forward current rating; supports stable operation without heatsink at ≤70°C ambient |
| IFSM | 50 A - Non-repetitive surge current (8.3ms); withstands load dump transients in vehicle electrical systems |
| VF @ 3A/25°C | ≤1.1 V - Forward voltage drop; limits conduction loss to <3.3W at full rated current |
| RθJL | 15 °C/W - Junction-to-lead thermal resistance; enables direct thermal path to PCB copper for passive cooling |
| ESD Rating | ≥10 kV (IEC 61000-4-2 contact) - Robust handling during automated SMT assembly and field service |
| Junction Temp | −40°C to +175°C - Full automotive temperature range support without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3A IF, but 1.3V VF @ 3A - +18% conduction loss vs. TSD3JAL | Higher thermal rise in compact layouts; requires larger copper area for same current | Select when legacy ST design reuse is prioritized over efficiency optimization |
| SB360-E3/5BT | 60V VRRM, 3A IF, Schottky architecture - lower VF (0.65V), but insufficient for 48V+ systems | Not suitable for automotive 24V/48V or telecom 48V PoE inputs due to voltage rating mismatch | Only viable in low-voltage (<30V) consumer electronics where ESD robustness is secondary |
Compared with STTH3L06S and SB360-E3/5BT, the TSD3JAL delivers optimal balance of 600V rating, 1.1V forward drop, and ≥10kV ESD immunity - making it uniquely suited for space-constrained, high-reliability 24–48V industrial and automotive rectification where thermal and surge margins are critical.

FAQ
What is the maximum repetitive peak reverse voltage rating for TSD3JAL?
The TSD3JAL has a specified VRRM of 600 V, verified per JEDEC test conditions at TA = 25°C. This rating allows safe operation in 48V automotive and telecom systems with ≥2.5× voltage margin over nominal rail levels, and is confirmed in the Absolute Maximum Ratings table of Taiwan Semiconductor's A2309 datasheet revision.
Does TSD3JAL meet AEC-Q101 stress testing requirements?
Yes, the TSD3JAL is qualified to AEC-Q101-001 H3B class for human-body-model ESD (≥8 kV), as documented in the Immunity to Electrical Static Discharge section of its official datasheet. It also passes JESD201 Class 2 whisker testing and UL 94V-0 flammability requirements - all verified for the Thin SMA packaged TSD3JAL variant.
What is the forward voltage drop of TSD3JAL at 3A and 25°C?
The TSD3JAL exhibits a maximum forward voltage drop of 1.1 V at IF = 3 A and TJ = 25°C, per the Electrical Specifications table. At 1.5 A and 25°C, typical VF is 0.90 V. These values are measured using 0.3 ms pulse width to avoid self-heating effects.
Is TSD3JAL compatible with lead-free reflow soldering processes?
Yes, the TSD3JAL uses matte tin-plated leads compliant with J-STD-002 solderability standards and rated for lead-free reflow profiles. Its moisture sensitivity level is J-STD-020 Level 1, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly.
What package type does TSD3JAL use, and what are its key mechanical dimensions?
The TSD3JAL uses the Thin SMA package per JEDEC DO-221AC variation, with overall dimensions of 4.40 mm × 2.70 mm × 1.45 mm. The cathode is marked by a visible band, and the device weighs approximately 0.030 g. Pad layout recommendations and mechanical drawings are provided in the Package Outline Dimensions section of the datasheet.
