Product details
Overview
TLD6S30AH from Taiwan Semiconductor is a unidirectional, AEC-Q101-qualified transient voltage suppressor (TVS) in DO-218AB package, rated for 30 V working stand-off voltage, 33.3–36.8 V breakdown voltage at 5 mA, and 4600 W peak pulse power (10/1000 µs), designed for automotive load dump surge protection in 12 V/24 V systems.
For engineers reviewing the TLD6S30AH datasheet, TLD6S30AH pinout, TLD6S30AH application, or TLD6S30AH equivalent, key selection criteria include clamping voltage (48.4 V at 95 A), junction temperature capability (−55 °C to +175 °C), IEC 61000-4-2 Level 4 ESD immunity, ISO 7637-2 compliance, and DO-218AB thermal performance (RθJC = 0.85 °C/W).
Technical Context
The TLD6S30AH employs junction passivation optimized design technology to sustain 175 °C junction operation and meet stringent automotive reliability requirements. It delivers 4600 W non-repetitive peak impulse power under 10/1000 µs waveform and 3600 W under 10/10000 µs waveform, with clamping voltage tightly specified at 48.4 V at 95 A IPPM.
Its unidirectional configuration provides reverse-biased transient suppression with 10 µA max leakage at 30 V (25 °C) and 150 µA at 175 °C. Thermal performance is validated with RθJC = 0.85 °C/W under ideal heatsink conditions, supporting high-power surge handling in compact surface-mount layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Lower PPPM (400 W), SMA package, RθJC ≈ 50 °C/W, VC = 48.4 V same but lower surge current rating (62 A) | Not qualified to AEC-Q101; limited to non-automotive industrial use | Choose SMAJ30A only for cost-sensitive, non-automotive applications with lower surge energy requirements |
| TPSMD30A | Same DO-218AB package, AEC-Q101 qualified, PPPM = 4600 W, but VC = 49.9 V (higher clamping), VBR = 33.3–37.1 V | Compatible with identical PCB footprint but requires verification of downstream voltage tolerance margin | Select TPSMD30A if alternate sourcing is needed and 1.5 V higher clamping voltage is acceptable in system design |
Compared with SMAJ30A and TPSMD30A, the TLD6S30AH offers identical clamping voltage and superior thermal resistance (0.85 °C/W vs. ~1.2–1.5 °C/W), enabling higher sustained surge duty cycles in confined engine bay spaces without thermal runaway.

FAQ
What is the maximum clamping voltage of the TLD6S30AH under standard test conditions?
The TLD6S30AH has a maximum clamping voltage (VC) of 48.4 V when subjected to a 10/1000 µs peak pulse current of 95 A. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuits during surge events. The TLD6S30AH maintains this clamping performance across its full operating temperature range, making it suitable for under-hood automotive applications where ambient temperatures exceed 100 °C.
Is the TLD6S30AH qualified for automotive applications?
Yes, the TLD6S30AH is AEC-Q101 qualified and meets ISO 7637-2 and ISO 16750-2 surge specifications, as well as IEC 61000-4-2 Level 4 ESD immunity. Its construction includes junction passivation optimized design, moisture sensitivity level 1 per J-STD-020, and operates reliably from −55 °C to +175 °C junction temperature. These attributes confirm its suitability for critical automotive subsystems including ECUs, BCMs, and ADAS modules.
What package type does the TLD6S30AH use, and what are its thermal characteristics?
The TLD6S30AH uses the DO-218AB surface-mount package, featuring matte tin-plated leads and UL 94V-0 molding compound. Its junction-to-case thermal resistance (RθJC) is 0.85 °C/W under ideal heatsink conditions - significantly lower than SMA/SMB alternatives - enabling efficient heat extraction during repetitive surge events. The device weighs 2.682 g and supports reflow soldering per J-STD-002 standards.
How does the TLD6S30AH compare to the TLD6S30A variant?
The TLD6S30AH and TLD6S30A share identical electrical specifications, including VWM = 30.0 V, VBR = 33.3–36.8 V, and VC = 48.4 V. The "H" suffix denotes tape-and-reel packaging (750 pcs/reel), while TLD6S30A may refer to bulk or alternate packaging formats. Both are manufactured in the same DO-218AB package and meet identical AEC-Q101 and surge compliance requirements.
What is the leakage current specification for the TLD6S30AH at maximum operating temperature?
At VWM = 30.0 V and TJ = 175 °C, the TLD6S30AH exhibits a maximum blocking leakage current (IR) of 150 µA. At 25 °C, the leakage is ≤10 µA under the same voltage. This low, temperature-stable leakage ensures minimal power loss in always-on vehicle networks and avoids false triggering in high-impedance sensing circuits powered from protected rails.
