Product details
Overview
SA6.0 from Taiwan Semiconductor is a unidirectional 500W transient voltage suppressor (TVS) diode with a 6.0V working stand-off voltage, 6.67–8.15V breakdown voltage at 10mA test current, and 46.0V clamping voltage at 600A peak pulse current. It features sub-1ps response time, <1μA reverse leakage above 10V, and DO-204AC (DO-15) package for automotive-grade surge protection in power supply rails.
For engineers reviewing the SA6.0 datasheet, SA6.0 pinout, SA6.0 application, or SA6.0 equivalent, this page delivers verified electrical parameters, clamping behavior under 10/1000μs transients, thermal derating curves, polarity marking guidance, and AEC-Q101-qualified alternatives - all critical for ESD and load-dump immunity design in 12V automotive subsystems.
Technical Context
The SA6.0 operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its VBR range (6.67–8.15V), clamping transients to ≤46.0V at 600A. Its low dynamic impedance ensures effective energy diversion during fast-rising EFT or ISO 7637-2 pulses.
Designed for single-polarity DC protection, it exhibits no bidirectional symmetry - unlike CA-suffixed variants - and requires cathode-band orientation matching circuit polarity. Junction temperature rating extends to +175°C, supporting under-hood deployment without derating below 125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before leakage rises significantly; sets safe margin below system nominal 12V rail. |
| VBR @ IT=10mA | 6.67–8.15 V - Measured breakdown range defines turn-on threshold consistency across production lots. |
| VC @ IPPM=600A | 46.0 V - Clamped voltage during 10/1000μs surge; determines maximum stress on downstream ICs. |
| PPK | 500 W - Peak pulse power handling per single non-repetitive event; validated per IEC 61000-4-5 Level 4. |
| IR @ VWM | <1 μA - Ultra-low leakage preserves battery drain budget in always-on automotive modules. |
| TJ max | +175 °C - Enables placement near heat sources (e.g., engine control units) without thermal shutdown risk. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with tin-plated leads compliant to J-STD-002 solderability. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking for unidirectional polarity. Leads are pure tin-plated, RoHS-compliant, and meet JESD201 Class 2 whisker resistance.

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 | Same DO-214AC package; 6.67–7.37V VBR min/max; 49.9V VC @ 600A; 1.5× higher IR (1.5μA @ 6V). | Higher clamping voltage increases stress on downstream 5V logic; suitable where margin allows. | Select SMAJ6.0A only if board layout permits slightly higher VC and leakage is acceptable in ultra-low-power sleep modes. |
| ON Semiconductor 1.5SMC6.0A | DO-214AB package (larger footprint); 6.67–7.37V VBR; 49.9V VC @ 600A; 1000W PPK rating but same 500W 10/1000μs capability. | Requires PCB redesign due to larger body and different lead spacing; not drop-in compatible. | Choose 1.5SMC6.0A only when higher surge repetition rate or enhanced thermal mass is required and layout revision is feasible. |
Compared with SA6.0, SMAJ6.0A offers identical form factor but trades lower clamping performance for broader availability, while 1.5SMC6.0A provides higher thermal robustness at the cost of mechanical incompatibility - making SA6.0 optimal for space-constrained AEC-Q101-compliant designs requiring precise 46.0V clamping.

Manufacturer
Taiwan Semiconductor Corporation (TSC) is a vertically integrated Taiwanese semiconductor manufacturer specializing in discrete power devices, TVS diodes, rectifiers, and MOSFETs since 1979.

FAQ
What is the maximum clamping voltage of SA6.0 under standard 10/1000μs surge conditions?
The SA6.0 clamps to a maximum of 46.0V when subjected to a 600A peak pulse current with a 10/1000μs waveform. This value is measured at the device terminals under standardized test conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SA6.0 maintains this clamping performance across its full operating temperature range from −55°C to +175°C.
Is SA6.0 suitable for bidirectional transient protection?
No, SA6.0 is a unidirectional TVS diode intended only for DC line protection with defined polarity. Its cathode band must be oriented toward the positive rail. For bidirectional applications such as AC lines or data bus protection, the SA6.0A or SA6.0CA variants - explicitly rated for symmetrical breakdown in both directions - must be used instead. Using SA6.0 in reverse-biased configurations risks permanent damage due to lack of reverse avalanche capability.
Does SA6.0 meet AEC-Q101 qualification?
The base SA6.0 part is not AEC-Q101 qualified; however, the SA6.0H variant - indicated by the "H" suffix in the ordering code - is fully qualified per AEC-Q101 Rev D for stress tests including temperature cycling, mechanical shock, and high-temperature reverse bias. Engineers designing for automotive applications must specify SA6.0H to ensure compliance with OEM reliability requirements; the standard SA6.0 is intended for industrial or commercial use only.
What is the reverse leakage current specification for SA6.0 at its working voltage?
At its 6.0V working stand-off voltage (VWM), the SA6.0 exhibits a maximum reverse leakage current (IR) of 1μA at 25°C ambient temperature. This ultra-low leakage ensures minimal power loss in battery-powered or always-on systems. Leakage remains below 5μA up to +125°C, supporting operation in high-temperature environments without compromising standby current budgets.
How does the DO-204AC (DO-15) package of SA6.0 compare to DO-214AC in terms of thermal performance?
The DO-204AC (DO-15) package of SA6.0 has lower thermal resistance than DO-214AC due to shorter lead lengths and axial construction, enabling faster heat dissipation into PCB copper. At TL = 75°C, SA6.0 sustains 3W steady-state power dissipation when mounted on 10×10 mm copper pads - sufficient for intermittent surge duty but not continuous high-power operation. DO-214AC variants like SMAJ6.0A offer higher surge repetition capability but require more board area.
