Product details
Overview
1.5KE220CAHA0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 220 V, clamping voltage 344 V at 4.5 A peak pulse current, and working stand-off voltage 175 V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE220CAHA0G datasheet, 1.5KE220CAHA0G pinout, 1.5KE220CAHA0G application, or 1.5KE220CAHA0G equivalent, this part delivers AEC-Q101-qualified surge immunity for 12 V/24 V vehicle subsystems, high-reliability industrial I/O protection, and ESD-hardened DC power interfaces requiring sub-5 ns response and <1 µA leakage above 10 V.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown voltage specified as 198–242 V at 1 mA test current and clamping voltage of 344 V under 10/1000 µs waveform. Its low dynamic impedance ensures stable clamping during fast transients, and junction temperature range spans −55 °C to +175 °C for under-hood deployment.
It meets ISO 7637-2 immunity requirements for automotive electronics, including load dump suppression and inductive switching spike absorption. The device uses silicon avalanche technology with pure tin-plated leads compliant to J-STD-002 and passes JESD 201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | 600 W rating, SMC package, lower clamping voltage (328 V), higher leakage (≤5 µA) | Better suited for space-constrained PCBs but limited to lower-energy transients | Select SMBJ220CA only if system-level surge energy is ≤600 W and board area is critical |
| 1.5SMC220CA | Same 1500 W rating, SMC package, identical VBR/VC, but non-AEC-Q101 rated | Applicable in industrial/commercial designs where automotive qualification is not required | Choose 1.5SMC220CA for cost-sensitive non-automotive applications needing same electrical performance |
Compared with 1.5KE220CAHA0G, SMBJ220CA offers smaller footprint but reduced surge capacity, while 1.5SMC220CA matches power and clamping specs but lacks AEC-Q101 validation-making 1.5KE220CAHA0G the sole choice for automotive-critical nodes requiring certified reliability.

FAQ
What does the 'CA' suffix indicate in 1.5KE220CAHA0G?
The 'CA' suffix in 1.5KE220CAHA0G denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. This differs from 'A' suffix parts (unidirectional), and is essential for protecting AC-coupled or floating signal lines where polarity reversal may occur during surge events. The 1.5KE220CAHA0G maintains identical VBR, VC, and PPK specifications in both directions.
Is 1.5KE220CAHA0G AEC-Q101 qualified, and what does the 'H' in the part number signify?
Yes, 1.5KE220CAHA0G is AEC-Q101 qualified-the 'H' in the ordering code explicitly indicates full compliance with the AEC-Q101 stress test standard for discrete semiconductors. This includes qualification for temperature cycling, high-temperature operating life, and mechanical shock, making 1.5KE220CAHA0G suitable for automotive powertrain, chassis, and body electronics where reliability under extreme conditions is mandatory.
What is the maximum clamping voltage of 1.5KE220CAHA0G, and under what test condition is it measured?
The maximum clamping voltage of 1.5KE220CAHA0G is 344 V, measured at a peak pulse current (IPP) of 4.5 A using the standardized 10/1000 µs double-exponential surge waveform. This value represents the upper limit of voltage seen by downstream circuitry during worst-case transient events, and is guaranteed across the full operating temperature range and production lot.
How does the DO-201 package of 1.5KE220CAHA0G affect thermal performance compared to surface-mount alternatives?
The DO-201 axial package of 1.5KE220CAHA0G provides superior thermal dissipation versus small SMD packages like SMA or SMC due to its larger copper lead mass and ability to mount directly to heatsinks or metal chassis. At TL = 75 °C, it sustains 5 W steady-state power, enabling reliable operation in high-ambient environments where SMD equivalents would require derating or additional thermal relief.
Can 1.5KE220CAHA0G be used in place of unidirectional TVS diodes like 1.5KE220A?
No-1.5KE220CAHA0G is strictly bidirectional and cannot replace unidirectional parts such as 1.5KE220A in circuits requiring polarity-specific clamping, like DC power rail protection with defined anode/cathode orientation. Substituting introduces risk of forward conduction during normal operation. For unidirectional applications, use 1.5KE220AHA0G instead; the 1.5KE220CAHA0G must only be deployed where symmetrical transient suppression is required and circuit topology supports bidirectional conduction.
