Product details
Overview
1.5SMC220CAHE3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It delivers 1500 W peak pulse power (10/1000 μs), clamps at 328 V under 4.6 A peak pulse current, and features a 185 V stand-off voltage with ±5% breakdown tolerance (209–231 V at 1 mA). It is AEC-Q101 qualified and used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC220CAHE3_A/H datasheet, 1.5SMC220CAHE3_A/H pinout, 1.5SMC220CAHE3_A/H application, or 1.5SMC220CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, SMC (DO-214AB) package compatibility, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This bidirectional TVS diode operates symmetrically across both polarities, enabling robust protection against voltage transients induced by lightning strikes, inductive load switching, and ESD events without polarity sensitivity. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 μA at 185 V).
The device sustains repetitive 10/1000 μs surges at 0.01% duty cycle and derates linearly above 25 °C ambient, with maximum junction temperature of +150 °C and thermal resistance of 75 °C/W (junction-to-ambient, on recommended 8.0 mm × 8.0 mm copper pads). It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Lower peak power (600 W), same VWM/VBR range, SMB package (smaller footprint, higher RθJA) | Suitable for space-constrained consumer electronics but not for automotive-level surge immunity | Select when board area is critical and surge energy is ≤600 W; verify thermal margin with RθJA = 110 °C/W |
| 1.5KE220CA | Higher RθJA (60 °C/W), axial-leaded DO-201 package, same electrical specs but manual assembly only | Used in legacy industrial equipment where through-hole mounting is required or reflow is unavailable | Choose for prototyping or low-volume repair; avoid in high-reliability automated production due to lead fatigue risk |
Compared with SMBJ220CA and 1.5KE220CA, the 1.5SMC220CAHE3_A/H uniquely combines AEC-Q101 qualification, 1500 W capability, and SMC surface-mount compatibility-making it the preferred choice for volume automotive and industrial designs requiring zero layout change from legacy SMC TVS footprints.

FAQ
What is the clamping voltage of the 1.5SMC220CAHE3_A/H under peak pulse conditions?
The 1.5SMC220CAHE3_A/H has a maximum clamping voltage (VC) of 328 V at 4.6 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88303 and defines the upper voltage limit imposed on protected circuitry during a standardized surge event. The 1.5SMC220CAHE3_A/H maintains this clamping performance bidirectionally and across its qualified operating temperature range.
Is the 1.5SMC220CAHE3_A/H suitable for automotive applications?
Yes, the 1.5SMC220CAHE3_A/H is AEC-Q101 qualified and specifically designated for automotive use via the "HE3" suffix and revision code "A/H". It has passed stress tests including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D. The 1.5SMC220CAHE3_A/H is deployed in engine control units, ADAS camera modules, and body control modules where bidirectional surge protection up to 1500 W is required.
What does the "CA" suffix indicate in 1.5SMC220CAHE3_A/H?
The "CA" suffix in 1.5SMC220CAHE3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both forward and reverse directions. Unlike unidirectional variants (e.g., 1.5SMC220A), the 1.5SMC220CAHE3_A/H has no polarity marking and is used where AC signals, differential pairs, or floating grounds require equal clamping behavior regardless of voltage polarity.
What is the thermal resistance of the 1.5SMC220CAHE3_A/H, and how does it affect layout?
The 1.5SMC220CAHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain safe junction temperatures under sustained power dissipation, PCB layout must allocate adequate copper area and avoid thermal bottlenecks. The 1.5SMC220CAHE3_A/H datasheet specifies minimum pad dimensions and recommends thermal vias for high-reliability applications.
Does the 1.5SMC220CAHE3_A/H meet UL safety standards?
Yes, the 1.5SMC220CAHE3_A/H is UL recognized under standard UL 497B (file number E136766) for use as a surge protective device in telecommunications and electronic equipment. This certification covers both unidirectional and bidirectional variants in the 1.5SMC Series and confirms compliance with dielectric withstand, flammability (UL 94 V-0), and failure mode requirements. The 1.5SMC220CAHE3_A/H carries this rating as part of its base qualification.
