Product details
Overview
TLD5S13AH from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-218AB package, rated for 13.0 V working stand-off voltage, 14.4–15.9 V breakdown voltage at 5 mA, and 3600 W peak pulse power (10/1000 µs). It operates from −55 °C to +175 °C and meets AEC-Q101, ISO 7637-2, ISO 16750-2, IEC 61000-4-2 Level 4, and ISO 10605 Level L4 for automotive load dump surge protection.
For engineers reviewing the TLD5S13AH datasheet, TLD5S13AH pinout, TLD5S13AH application, or TLD5S13AH equivalent, key selection criteria include its 21.5 V clamping voltage at 167 A peak current, 0.9 °C/W junction-to-case thermal resistance, unidirectional polarity, 10 µA max leakage at VWM, and DO-218AB mechanical compatibility with high-power automotive PCB layouts.
Technical Context
The TLD5S13AH employs junction passivation optimized design technology to sustain 175 °C junction temperature under sustained transients, enabling use in under-hood automotive environments. Its DO-218AB package supports high thermal dissipation with ideal heatsink mounting and delivers 3600 W non-repetitive peak impulse power using 10/1000 µs waveform.
It is specified for unidirectional operation only, with 2 V max forward voltage at 100 A and 500 A peak forward surge current (8.3 ms half-sine). Clamping performance is validated per ISO 7637-2 load dump testing, and it complies with moisture sensitivity level 1 per J-STD-020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Lower PPPM (400 W), SMA package, RθJC ≈ 50 °C/W, VC = 21.2 V @ 19.9 A | Not suitable for load dump; limited to low-energy ESD/surge events in infotainment or lighting | Select only for cost-sensitive non-automotive applications with <500 W surge exposure |
| SMCJ13A | Higher PPPM (1500 W), SMC package, RθJC ≈ 12 °C/W, VC = 21.5 V @ 70 A | Meets ISO 7637-2 Pulse 5a but not full load dump; insufficient for 3600 W requirement | Acceptable for mid-tier automotive modules where full load dump margin is relaxed |
Compared with SMAJ13A and SMCJ13A, the TLD5S13AH delivers 2.4× and 2.4× higher peak power handling respectively, with superior thermal resistance enabling direct integration into high-temperature engine bay designs without external heatsinking.

FAQ
What is the maximum clamping voltage of the TLD5S13AH under standard test conditions?
The TLD5S13AH has a maximum clamping voltage (VC) of 21.5 V when subjected to a 10/1000 µs peak pulse current of 167 A. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuits during worst-case transients. The TLD5S13AH maintains this clamping performance across its full operating temperature range, making it suitable for automotive environments where voltage overshoot must be tightly constrained.
Is the TLD5S13AH suitable for bidirectional transient protection?
No, the TLD5S13AH is a unidirectional TVS diode and is not rated for bidirectional surge suppression. Its electrical characteristics-including breakdown voltage, clamping behavior, and leakage-are specified only for reverse-biased operation. For applications requiring protection against both positive and negative transients (e.g., data lines or AC-coupled signals), a dedicated bidirectional TVS such as the TLD5S13AH-BD variant-or a separate pair-must be used instead of relying on the TLD5S13AH alone.
Does the TLD5S13AH meet AEC-Q101 reliability standards?
Yes, the TLD5S13AH is explicitly qualified to AEC-Q101 Rev D for stress testing including HTGB, HTRB, TST, and mechanical shock. This qualification confirms its suitability for automotive electronic systems where long-term reliability under thermal cycling, humidity, and vibration is mandatory. The TLD5S13AH's 175 °C junction rating and DO-218AB construction further support its deployment in engine control, transmission, and ADAS modules certified to ASIL-B or ASIL-C functional safety levels.
What is the thermal resistance from junction to case for the TLD5S13AH?
The TLD5S13AH has a typical junction-to-case thermal resistance (RθJC) of 0.9 °C/W when mounted on an ideal heatsink. This low value reflects the DO-218AB package's enhanced thermal path and enables efficient heat transfer from the silicon die to the PCB copper pour or external heatsink. In practice, achieving this value requires proper solder coverage, thermal pad design per TSC's suggested layout, and adequate copper area-critical for sustaining repeated 3600 W surges in automotive load dump scenarios.
How does the TLD5S13AH compare to the TLD5S13A variant?
The TLD5S13AH and TLD5S13A share identical electrical specifications, package (DO-218AB), and marking code (TLD5S13A), but differ in packaging format: "H" denotes tape-and-reel (750 pcs/reel), while non-H variants may ship in bulk or different reels. No parametric, reliability, or performance differences exist between them-the "H" suffix is purely a logistics designation per Taiwan Semiconductor's ordering code convention.
