Product details

Overview

SA6.0-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 500 W peak pulse power (10/1000 µs), 6.0 V stand-off voltage (V_WM), 6.67–7.37 V breakdown voltage (V_BR at 10 mA), 48.5 V clamping voltage (V_C) at 600 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the SA6.0-E3/54 datasheet, SA6.0-E3/54 pinout, SA6.0-E3/54 application, or SA6.0-E3/54 equivalent, this device serves as a robust, RoHS-compliant, lead-free transient suppressor for automotive infotainment power inputs, industrial sensor I/O protection, and telecom line interface surge immunity - with verified clamping performance, low incremental surge resistance, and fast sub-nanosecond response.

Technical Context

The SA6.0-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling precise bidirectional clamping behavior in unidirectional configuration. Its 6.0 V stand-off voltage supports 5 V rail protection while maintaining low leakage (<600 µA at V_WM) and stable temperature coefficient (5 %/°C).

It delivers 500 W peak pulse power under standardized 10/1000 µs waveform, with 48.5 V clamping at 600 A IPPM and 3.5 V forward voltage at 100 A - confirming suitability for high-energy transients in automotive load-dump and inductive switching scenarios.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	6.0 V - Maximum continuous reverse operating voltage before conduction; sets safe margin above 5 V nominal supply.
V_BR (min/max)	6.67 V / 7.37 V at 10 mA - Confirmed avalanche onset range ensures predictable turn-on during overvoltage events.
V_C @ I_PPM	48.5 V at 600 A - Clamped voltage limits downstream IC stress during 500 W transient surges.
P_PPM	500 W - Peak pulse power rating per 10/1000 µs waveform defines maximum transient energy absorption capability.
I_PPM	600 A - Peak pulse current capacity validates robustness against ISO 7637-2 Pulse 5a/b load-dump events.
T_J max	175 °C - Maximum junction temperature enables operation in under-hood automotive environments.
Package	DO-204AC (DO-15) - Standard axial-leaded through-hole package with matte tin-plated leads, UL 94 V-0 molding.

Pinout & Package

DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking on one end. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards. E3 suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry / low-side connection	Connected to ground or low-potential node in unidirectional TVS configuration.
Cathode (banded end)	Reverse-biased clamping node	Connected to protected line (e.g., 5 V rail); conducts avalanche current when V_LINE exceeds V_BR.

Key Features

Feature	Design Value
Glass-passivated junction	Ensures stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress.
500 W peak pulse power (10/1000 µs)	Supports compliance with ISO 7637-2 and IEC 61000-4-5 Level 4 surge immunity requirements.
AEC-Q101 qualified (E3 variant is commercial; HE3 is AEC-Q101)	SA6.0-E3/54 is RoHS-compliant commercial grade; AEC-Q101 version requires HE3 suffix - critical for automotive OEM designs.
Low clamping ratio (V_C/V_BR ≈ 6.9)	Minimizes voltage overshoot during clamping, reducing risk of damage to downstream 5 V logic and interface ICs.
Fast response time (<1 ns)	Engages before transient-induced damage occurs in sensitive CMOS and MOSFET gate circuits.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMAJ6.0A	Same V_WM (6.0 V), identical DO-214AC (SMA) package; slightly higher V_C (49.9 V @ 600 A) and lower P_PPM (400 W).	Surface-mount alternative requiring PCB re-layout; better suited for space-constrained designs but lacks axial-leaded mechanical robustness.	Select SMAJ6.0A only if SMT assembly and footprint reduction outweigh need for through-hole mounting strength and thermal mass.
1.5KE6.8A	Higher V_WM (6.8 V), larger DO-201AD package, same 500 W rating; V_C = 11.2 V @ 44.2 A - not comparable at same current level due to lower IPPM (44.2 A vs. 600 A).	Designed for lower-energy transients; unsuitable for ISO 7637-2 load-dump where SA6.0-E3/54's 600 A IPPM is essential.	1.5KE6.8A is not a functional substitute for SA6.0-E3/54 in high-current surge applications - use only for low-energy ESD or signal-line clamping.

Compared with SMAJ6.0A and 1.5KE6.8A, SA6.0-E3/54 uniquely combines 600 A peak pulse current capability, DO-204AC mechanical stability, and 48.5 V clamping in a commercial RoHS-compliant axial package - making it optimal for automotive and industrial through-hole surge protection where high IPPM and proven thermal endurance are mandatory.

FAQ

What is the clamping voltage of SA6.0-E3/54 at its rated peak pulse current?

The SA6.0-E3/54 has a maximum clamping voltage (V_C) of 48.5 V at 600 A peak pulse current (I_PPM) under the standard 10/1000 µs waveform. This value is measured per Figure 7 in Vishay document 88378 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The SA6.0-E3/54 maintains this clamping performance consistently across its operating temperature range.

Is SA6.0-E3/54 AEC-Q101 qualified?

No - SA6.0-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial-grade construction. For AEC-Q101 qualification, the correct part is SA6.0HE3/54 (HE3 suffix). The SA6.0-E3/54 datasheet explicitly states that AEC-Q101 qualification applies only to HE3 variants, and the E3 version is intended for non-automotive industrial and consumer applications where full automotive qualification is not required.

What does the "/54" in SA6.0-E3/54 signify?

The "/54" in SA6.0-E3/54 is Vishay's preferred package code denoting 13-inch diameter paper tape and reel packaging with a base quantity of 4000 units per reel. It is not a revision or variant identifier - all electrical and mechanical specifications of SA6.0-E3/54 match those of SA6.0A-E3 in the SA5.0A–SA170A family datasheet (Document Number 88378, Revision 18-Sep-12). The SA6.0-E3/54 is functionally identical to SA6.0A-E3.

Can SA6.0-E3/54 be used for bidirectional transient protection?

No - SA6.0-E3/54 is a unidirectional TVS diode, indicated by the "A" suffix (e.g., SA6.0A). Bidirectional versions use the "CA" suffix (e.g., SA6.0CA). The SA6.0-E3/54 has a cathode band and conducts only in reverse avalanche mode; applying significant reverse voltage to its anode will cause permanent failure. For AC or symmetrical transient protection, SA6.0CA-E3/54 must be selected instead.

What is the maximum leakage current of SA6.0-E3/54 at its stand-off voltage?

The maximum reverse leakage current (I_D) of SA6.0-E3/54 is 600 µA at its rated stand-off voltage (V_WM) of 6.0 V and ambient temperature of 25 °C. This value is specified in the Electrical Characteristics table of Vishay document 88378 and remains below 1 mA across the full operating temperature range, ensuring minimal impact on low-power sensor or standby circuits powered by the protected rail.
