Product details
Overview
SA160CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 160 V stand-off voltage (VWM), 209 V maximum breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), 1.9 A peak pulse current (IPPM), and AEC-Q101 qualification for automotive use.
For engineers reviewing the SA160CAHE3/54 datasheet, SA160CAHE3/54 pinout, SA160CAHE3/54 application, or SA160CAHE3/54 equivalent, this device serves as a robust overvoltage protection component in automotive ECUs, industrial sensor interfaces, and telecom line cards where bidirectional surge immunity and high-temperature operation up to 175 °C are required.
Technical Context
The SA160CAHE3/54 operates as a bidirectional avalanche diode with symmetrical clamping behavior in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while its 10/1000 µs waveform rating reflects standardized surge immunity testing per R.E.A. definitions.
Designed for repetitive transient suppression, it supports 0.01% duty cycle operation and derates linearly above 25 °C ambient - maintaining 3.0 W steady-state power dissipation at 75 °C lead temperature. The device exhibits a +196 mV/°C temperature coefficient of VBR, consistent with high-voltage TVS diodes in the SAxxCA family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR (min/max) | 178 V / 209 V at 1.0 mA - Ensures reliable avalanche conduction onset across manufacturing lot and temperature variation. |
| VC @ IPPM | 259 V - Clamped voltage during 1.9 A 10/1000 µs surge; determines maximum stress imposed on downstream components. |
| IPPM | 1.9 A - Peak surge current capability under standard 10/1000 µs waveform; directly limits protected line impedance. |
| PPPM | 500 W - Surge energy handling capacity; enables compliance with IEC 61000-4-5 Level 3 (1 kV/2 Ω) when combined with series impedance. |
| TJ max | +175 °C - Junction temperature limit supporting under-hood automotive deployment and high-ambient industrial environments. |
| Leakage @ VWM | <1.0 µA - Minimal standby power loss and negligible loading on 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 |
|---|---|---|---|
| SMAJ160A-E3/54 | Unidirectional; same VWM/VBR/PPPM, but requires polarity-aware layout and lacks bidirectional symmetry. | Suitable only for DC-biased lines where polarity is fixed; not usable on AC or floating nodes. | Select SMAJ160A-E3/54 only if circuit topology guarantees unidirectional surge direction and space constraints favor SMC package. |
| 1.5KE160CA | Same bidirectional function and VWM, but larger DO-201AD package (higher IPPM = 2.2 A, higher PPPM = 1500 W). | Better suited for high-energy surge zones (e.g., AC mains input), but incompatible with DO-15 footprint. | Choose 1.5KE160CA when system-level surge testing exceeds 500 W requirements and PCB layout allows larger package. |
Compared with SMAJ160A-E3/54 and 1.5KE160CA, the SA160CAHE3/54 uniquely balances AEC-Q101 qualification, DO-15 compactness, and true bidirectional symmetry - making it optimal for space-constrained automotive and industrial signal-line protection where polarity cannot be assumed.

FAQ
What is the clamping voltage of SA160CAHE3/54 at its rated peak pulse current?
The SA160CAHE3/54 has a maximum clamping voltage (VC) of 259 V at its rated peak pulse current (IPPM) of 1.9 A under the standard 10/1000 µs waveform. This value is measured per Figure 9 in the Vishay datasheet 88378 and defines the upper voltage limit imposed on protected circuitry during surge events. The SA160CAHE3/54 maintains this clamping performance across its full operating temperature range.
Is SA160CAHE3/54 suitable for automotive applications?
Yes, the SA160CAHE3/54 is AEC-Q101 qualified, as confirmed by the HE3 suffix and Note (1) in the Vishay datasheet 88378. It is rated for operation from –55 °C to +175 °C and tested for reliability under automotive stress conditions including high-temperature operating life and thermal cycling. The SA160CAHE3/54 is commonly deployed in engine control units, body electronics, and infotainment systems requiring bidirectional surge protection.
Does SA160CAHE3/54 have polarity markings on its DO-15 package?
No, the SA160CAHE3/54 does not feature polarity markings such as a cathode band because it is a bidirectional TVS diode. Both terminals are functionally identical and symmetric - either can serve as anode or cathode depending on transient polarity. This eliminates orientation errors during placement and simplifies layout for AC-coupled or floating circuits. The SA160CAHE3/54's bidirectional nature is explicitly defined in the "DEVICES FOR BIDIRECTION APPLICATIONS" section of the datasheet.
What is the maximum steady-state power dissipation of SA160CAHE3/54?
The SA160CAHE3/54 has a maximum steady-state power dissipation (PD) of 3.0 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C, as specified in the "MAXIMUM RATINGS" table of datasheet 88378. This rating decreases linearly above 25 °C ambient per the derating curve in Figure 2. The SA160CAHE3/54 is intended for transient suppression, not continuous power dissipation - normal operation involves near-zero DC power draw due to sub-µA leakage at VWM.
How does SA160CAHE3/54 differ from SA160AHE3/54?
The SA160CAHE3/54 is bidirectional, whereas SA160AHE3/54 is unidirectional - indicated by the "CA" vs. "A" suffix per Vishay's naming convention. The SA160CAHE3/54 clamps surges of either polarity symmetrically and has no cathode marking; the SA160AHE3/54 clamps only in reverse bias and requires correct orientation. Their VWM, VBR, and PPPM ratings are identical, but the SA160CAHE3/54 is required for AC, differential, or floating node protection where polarity is undefined.
