Product details

Overview

SA6.0CA from Taiwan Semiconductor is a bidirectional 500W transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, with 6.67–7.37 V breakdown voltage (V_BR), 6.0 V working stand-off voltage (V_WM), and 50.0 A peak pulse current (I_PPM) at 10/1000 μs waveform-designed for ESD and electrical fast transient protection in automotive lighting control modules.

For engineers reviewing the SA6.0CA datasheet, SA6.0CA pinout, SA6.0CA application, or SA6.0CA equivalent, key selection criteria include bidirectional clamping capability, low leakage (<1 μA @ V_WM), AEC-Q101 qualification, DO-15 mechanical compatibility, and verified 500W surge rating per IEC 61000-4-5.

Technical Context

The SA6.0CA operates as a bidirectional avalanche diode, symmetrically clamping transients in both polarities with identical V_BR min/max (6.67–7.37 V) and V_C = 10.3 V at 50.0 A. Its junction temperature range spans –55°C to +175°C, supporting under-hood automotive environments.

It delivers 500W peak pulse power at T_A = 25°C, derated linearly above ambient per Fig.2, and exhibits <1.0 ps response time for unidirectional mode (and 5.0 ns for bidirectional operation), enabling sub-nanosecond suppression of ESD events per IEC 61000-4-2.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	6.0 V - Maximum continuous reverse voltage before conduction begins; sets system operating margin below clamping threshold.
V_BR @ I_T = 10 mA	6.67–7.37 V - Verified breakdown range ensures reliable turn-on during transients without premature leakage.
V_C @ I_PPM = 50.0 A	10.3 V - Clamped voltage during 10/1000 μs surge; limits downstream IC stress to safe levels.
I_PPM	50.0 A - Peak surge current handling capacity at rated waveform; defines maximum transient energy absorption.
P_PK	500 W - Non-repetitive peak pulse power rating; validates compliance with IEC 61000-4-5 Level 4.
I_R @ V_WM	<1 μA - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss.
T_J max	+175 °C - Extended junction temperature rating enables use in high-ambient automotive engine compartments.

Pinout & Package

Package: DO-204AC (DO-15), axial leaded, RoHS-compliant, halogen-free molding compound, pure tin-plated leads solderable per J-STD-002, polarity marked by cathode band (bidirectional symmetry eliminates functional polarity distinction).

Pin/Terminal	Circuit Role	Design Meaning
Anode / Cathode (symmetrical)	Bidirectional avalanche junction terminals	No functional polarity-either lead serves as input/output for transient suppression in AC or floating systems.
Lead 1	Current path terminal	Provides low-inductance path to ground or rail; requires minimum 9.5 mm lead length for 3 W steady-state dissipation rating.
Lead 2	Current path terminal	Matches Lead 1 electrically; bidirectional symmetry allows orientation-agnostic PCB placement.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per JESD47.
500W surge rating (10/1000 μs)	Meets IEC 61000-4-5 surge immunity requirements for Level 4 (4 kV line-to-line) in 50 Ω source impedance systems.
Bidirectional clamping	Enables single-device protection of AC-coupled or floating interfaces without external polarity management circuitry.
Fast response: ≤5.0 ns	Guarantees clamping activation before transient energy couples into sensitive analog or digital inputs.
Low IR <1 μA @ V_WM	Prevents signal distortion or bias shift in high-impedance sensor or communication lines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Littelfuse SMAJ6.0A	Unidirectional; V_C = 10.3 V @ 50.0 A; same DO-214AC package but different footprint.	Requires polarity-aware layout; unsuitable for AC or floating-bus protection without additional components.	Select only when unidirectional clamping suffices and PCB layout accommodates SMA package.
ON Semiconductor 1.5KE6.8CA	Higher P_PK = 1500 W; larger DO-201AD package; V_C = 11.5 V @ 130 A.	Over-specified for 500W needs; introduces higher parasitic inductance and board area penalty.	Choose only if legacy 1.5KE footprint reuse is mandatory and surge margin >3× is required.

Compared with SMAJ6.0A and 1.5KE6.8CA, the SA6.0CA uniquely combines bidirectional operation in DO-15, AEC-Q101 qualification, and precise 500W/10.3 V clamping-enabling compact, automotive-grade protection without polarity constraints or footprint conversion.

FAQ

What is the clamping voltage of SA6.0CA at its rated peak pulse current?

The SA6.0CA has a maximum clamping voltage (V_C) of 10.3 V when subjected to its rated peak pulse current of 50.0 A under the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream ICs experience minimal overvoltage stress during surge events. The SA6.0CA maintains this performance across its full operating temperature range.

Is SA6.0CA suitable for automotive applications?

Yes, SA6.0CA is AEC-Q101 qualified and rated for junction temperatures up to +175°C, making it suitable for under-hood and body-control module applications. Its bidirectional architecture, low leakage (<1 μA), and 500W surge rating meet ISO 7637-2 and IEC 61000-4-5 requirements. The SA6.0CA is commonly deployed in LED headlamp drivers and infotainment power rails.

How does SA6.0CA differ from SA6.0A?

The SA6.0CA is bidirectional, while SA6.0A is unidirectional. Both share identical V_BR (6.67–7.37 V), V_WM (6.0 V), and V_C (10.3 V), but SA6.0CA clamps transients equally in both directions-critical for AC-coupled or floating-bus protection. SA6.0CA replaces two unidirectional devices in symmetrical layouts, simplifying design and reducing BOM count.

What is the package type and lead finish of SA6.0CA?

The SA6.0CA uses the DO-204AC (DO-15) axial package with pure tin-plated leads compliant with J-STD-002 solderability standards. It weighs approximately 0.400 g and features UL 94V-0 flammability-rated molding compound. The cathode band marking applies only to unidirectional variants; SA6.0CA has no functional polarity marking due to bidirectional symmetry.

Does SA6.0CA meet RoHS and halogen-free requirements?

Yes, SA6.0CA is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and all materials comply with EU Directive 2011/65/EU. This ensures environmental safety and process compatibility with lead-free reflow profiles used in modern electronics assembly.
