Product details
Overview
TSD2GH from Taiwan Semiconductor is a 2 A, 400 V glass-passivated surface-mount rectifier diode with AEC-Q101 qualification, 50 A surge capability, and ≥8 kV HBM ESD rating-designed for automotive DC-DC converters and snubber circuits.
For engineers reviewing the TSD2GH datasheet, TSD2GH pinout, TSD2GH application, or TSD2GH equivalent, key selection factors include its DO-214AA (SMB) package, low VF (0.90 V @ 2 A, 25°C), 175°C max junction temperature, and JESD201 Class 2 whisker resistance for high-reliability automotive PCB assembly.
Technical Context
The TSD2GH is a single-die, unidirectional silicon rectifier optimized for high-reliability automotive power conversion. Its glass-passivated junction ensures stable reverse leakage (<1 µA @ 25°C, <50 µA @ 125°C) and robust thermal performance (RθJL = 26°C/W).
It delivers low forward voltage drop across operating temperatures (0.75–1.00 V @ 2 A), supports 8.3 ms surge pulses up to 50 A, and meets stringent ESD immunity per AEC-Q101-001 (H3B), IEC 61000-4-2 (≥15 kV air), and ISO 10605 (L4).

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | Same DO-214AA package, 2 A/400 V, but VF = 1.15 V (max) @ 2 A; no AEC-Q101 qualification | Targeted at industrial power supplies-not validated for automotive temperature cycling or ESD stress | Acceptable for cost-sensitive non-automotive designs where ESD immunity and 125°C IR stability are not required |
| SB240-E3/5BT | DO-214AA, 2 A/40 V - significantly lower VRRM; VF = 0.54 V @ 2 A; RoHS/halogen-free | Limited to 12 V systems; unsuitable for 24/48 V automotive bus or snubber use | Only viable for low-voltage LED drivers or consumer adapters where 400 V blocking is unnecessary |
Compared with STTH2R04 and SB240-E3/5BT, the TSD2GH uniquely combines AEC-Q101 qualification, 400 V VRRM, and ≤1.00 V VF in a single SMB package-making it the only option qualified for under-hood DC-DC and snubber roles requiring both high voltage and high ESD robustness.

FAQ
What is the maximum junction temperature rating for the TSD2GH?
The TSD2GH has a maximum junction temperature (TJ) of +175°C, verified per AEC-Q101 thermal stress testing. This enables reliable operation in under-hood automotive environments where ambient temperatures exceed 125°C. The device maintains specified electrical parameters-including reverse leakage and forward voltage-up to this limit when properly mounted on a 10 mm × 10 mm copper pad per JEDEC standards. Thermal design must account for RθJA = 73°C/W in still air.
Does the TSD2GH meet AEC-Q101 qualification, and what tests does that include?
Yes, the TSD2GH is AEC-Q101 qualified per version A2102. Certification covers HTOL (1000 hrs @ 175°C), temperature cycling (−55°C to +175°C, 1000 cycles), unbiased HAST (96 hrs @ 130°C/85% RH), and ESD per AEC-Q101-001 (H3B class, ≥8 kV HBM). Full qualification reports are available upon request from Taiwan Semiconductor and are referenced in the official TSD2GH datasheet revision A2102.
What is the marking code printed on the TSD2GH device body?
Each TSD2GH device is laser-marked with "TSD2G" on the cathode end, followed by green compound indicator "G", date code "YW", and factory code "F". The full orderable part number TSD2GH does not appear on the device; only the shortened marking "TSD2G" is used for identification on the DO-214AA (SMB) package body per standard semiconductor marking conventions.
How does the TSD2GH's ESD performance compare to standard industrial rectifiers?
The TSD2GH achieves ≥8 kV HBM (AEC-Q101 H3B), ≥15 kV IEC 61000-4-2 contact, and ≥25 kV ISO 10605 air discharge-far exceeding typical industrial rectifiers (often ≤2 kV HBM). This is enabled by proprietary junction passivation and leadframe design. In automated SMT lines, this eliminates post-placement ESD screening and reduces field return rates in automotive assembly, unlike non-qualified alternatives such as STTH2R04.
Is the TSD2GH suitable for snubber circuit applications, and why?
Yes, the TSD2GH is explicitly recommended for snubber circuits per its official applications list. Its 50 A IFSM (8.3 ms), low junction capacitance (20 pF @ 4 V), and fast recovery characteristics enable effective clamping of MOSFET/FET turn-off spikes in automotive DC-DC and motor drivers. Combined with AEC-Q101 qualification and 175°C TJ rating, it sustains repeated high-energy transients without parameter drift-critical for snubbers in safety-critical power stages.
