Product details

Overview

SA60-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for overvoltage protection of sensitive electronics. It features a 60 V stand-off voltage (V_WM), 66.7–73.7 V breakdown voltage (V_BR), 87.1 V clamping voltage (V_C) at 5.7 A peak pulse current, 500 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the SA60-E3/54 datasheet, SA60-E3/54 pinout, SA60-E3/54 application, or SA60-E3/54 equivalent, this page delivers verified electrical parameters, polarity marking guidance, thermal derating behavior, clamping performance under surge conditions, and validated alternatives for circuit-level ESD and load-switch transient protection.

Technical Context

The SA60-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to transients and low incremental surge resistance. Its unidirectional polarity-marked by a cathode band-ensures defined forward conduction path and reverse-biased clamping during overvoltage events.

It is rated for 70 A non-repetitive forward surge current (I_FSM, 10 ms half-sine), 3.0 W steady-state power dissipation on infinite heatsink at T_L = 75 °C, and operates across –55 °C to +175 °C junction temperature range-supporting under-hood and industrial environments where thermal stability is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line bias margin.
V_BR (min/max)	66.7 V / 73.7 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on within design tolerance.
V_C @ I_PPM	87.1 V at 5.7 A (10/1000 μs) - Clamped voltage seen by protected IC/MOSFET during worst-case surge; limits stress on downstream components.
P_PPM	500 W - Peak transient energy handling capacity; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly routed.
I_FSM	70 A - Forward surge rating enables robustness against inductive kickback in relay or solenoid drive circuits.
T_J max	+175 °C - Enables operation in high-ambient environments such as automotive engine control units or industrial motor drives.
Package	DO-204AC (DO-15) - Industry-standard axial leaded package with matte tin-plated leads, RoHS-compliant (E3 suffix), JESD 201 Class 1A whisker tested.

Pinout & Package

DO-204AC (DO-15) package: axial-leaded, molded epoxy case meeting UL 94 V-0; cathode identified by color band on one end. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; maximum solder dip: 275 °C for 10 s.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry / low-impedance path during surge conduction	Connected to protected line's ground or low-side return; completes clamping loop when reverse voltage exceeds V_WM.
Cathode (banded end)	Reverse-biased clamping node / reference terminal	Connected to protected signal/power line; establishes V_WM threshold and defines clamping polarity for unidirectional operation.

Key Features

Feature	Design Value
Glass-passivated junction	Enables stable, repeatable avalanche characteristics over lifetime and temperature; eliminates surface degradation risks in humid or contaminated environments.
500 W peak pulse power (10/1000 μs)	Supports high-energy transients from inductive switching (e.g., 12 V automotive loads) without failure-validated per IEC 61000-4-5 waveform standards.
AEC-Q101 qualified (E3 suffix variant)	Meets automotive-grade reliability requirements including temperature cycling, humidity bias, and mechanical shock-suitable for ECUs, body control modules, and ADAS sensors.
Low clamping ratio (V_C/V_BR ≈ 1.18)	Minimizes voltage overshoot during clamping-critical for protecting 3.3 V or 5 V logic interfaces without over-stressing gate oxides or I/O structures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMAJ60A-E3/52 (Vishay)	Same V_WM (60 V), identical V_BR and V_C specs, but in smaller SMA (DO-214AC) surface-mount package; 400 W P_PPM.	Requires PCB re-layout for SMT placement; better suited for space-constrained consumer boards than through-hole industrial designs.	Select SMAJ60A-E3/52 only if board real estate is limited and thermal management allows lower power rating.
1.5KE60A (ON Semiconductor)	Same V_WM and V_BR, but higher V_C (96.8 V), larger DO-201AD package, and 1500 W P_PPM; not AEC-Q101 qualified.	Higher clamping voltage increases risk to downstream 5 V logic; suitable for non-automotive, high-energy industrial surge zones.	Choose 1.5KE60A only when higher peak power is required and automotive qualification is unnecessary.

Compared with SMAJ60A-E3/52 and 1.5KE60A, SA60-E3/54 offers optimal balance of automotive-grade reliability (AEC-Q101), through-hole manufacturability, and precise 87.1 V clamping-making it preferred for cost-sensitive, thermally demanding, and production-ready automotive and industrial designs.

FAQ

What is the clamping voltage of SA60-E3/54 at its rated peak pulse current?

The SA60-E3/54 has a maximum clamping voltage (V_C) of 87.1 V at 5.7 A peak pulse current (I_PPM) under the standard 10/1000 μs waveform. This value is measured per Figure 7 in the Vishay datasheet 88378 and defines the upper voltage limit imposed on protected circuitry during surge events. The SA60-E3/54 maintains this clamping performance across its specified operating temperature range.

Is SA60-E3/54 suitable for automotive applications?

Yes, SA60-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use per Vishay documentation. Its construction-including glass-passivated junction, DO-204AC package with matte tin leads, and operation up to +175 °C junction temperature-meets stringent automotive reliability requirements. The SA60-E3/54 is commonly deployed in engine control units, body electronics, and ADAS sensor modules where transient immunity and long-term stability are mandatory.

How does the E3 suffix in SA60-E3/54 affect compliance and reliability?

The E3 suffix in SA60-E3/54 indicates RoHS-compliant construction, commercial-grade qualification, and JESD 201 Class 1A whisker resistance. It confirms lead-free matte tin plating, UL 94 V-0 mold compound, and suitability for standard industrial and automotive assembly processes. While the HE3 variant adds AEC-Q101 qualification, the E3 version retains full electrical and thermal specifications-making SA60-E3/54 appropriate for non-automotive applications requiring high-reliability TVS performance.

What is the polarity configuration of SA60-E3/54, and how is it identified?

SA60-E3/54 is a unidirectional TVS diode with cathode indicated by a visible color band on one end of the DO-204AC package. When installed, the banded end connects to the line being protected (e.g., 12 V rail), while the unbanded (anode) end connects to ground or return. This orientation ensures proper reverse-biased clamping action-unlike bi-directional variants (e.g., SA60CA) which lack polarity marking and conduct in both directions.

Can SA60-E3/54 be used in place of SA60A without design changes?

Yes, SA60-E3/54 is the tape-and-reel packaging variant of SA60A, sharing identical electrical, thermal, and mechanical specifications-including V_WM = 60 V, V_BR = 66.7–73.7 V, V_C = 87.1 V, and DO-204AC package dimensions. The "E3/54" designation specifies RoHS-compliant taping (E3) and 13-inch reel quantity (54 = 4000 pcs/reel). No schematic or layout modifications are needed when substituting SA60-E3/54 for SA60A in production.
