Product details
Overview
1.5SMC82CAH from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 77.9–86.1 V, clamping voltage of 113 V at 13.9 A peak pulse current, and DO-214AB (SMC) package. It provides ESD and surge protection for automotive power lines, industrial I/O ports, and telecom interfaces requiring robust ISO 7637-2 Pulse 1/2a/2b/3a/3b immunity.
For engineers reviewing the 1.5SMC82CAH datasheet, 1.5SMC82CAH pinout, 1.5SMC82CAH application, or 1.5SMC82CAH equivalent, key selection criteria include bidirectional clamping capability, 113 V VC rating at 13.9 A, AEC-Q101 qualification, moisture sensitivity level 1, and compliance with IEC 61249-2-21 halogen-free requirements.
Technical Context
The 1.5SMC82CAH employs a glass-passivated silicon junction optimized for fast transient response (<1.0 ps), low leakage (<1 µA at 70.1 V), and stable bidirectional clamping in both polarities. Its thermal design supports 150 °C maximum junction temperature with RθJC = 15 °C/W and RθJA = 50 °C/W.
Designed for unidirectional and bidirectional surge suppression, it meets ISO 7637-2 test pulses without polarity dependence - electrical characteristics apply identically in forward and reverse directions per manufacturer specification. The device operates across -55 °C to +150 °C ambient and storage ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | 600 W rating, 85 V nominal VBR, SMB package (smaller footprint, lower PPK) | Lower power handling limits use to sub-1 kV surge environments; not suitable for ISO 7637-2 Pulse 1 | Select when board space is constrained and peak surge energy is ≤600 W |
| 1.5KE82CA | Through-hole TO-204AA (DO-41) package, same 1500 W rating and 82 V VBR range | Requires wave soldering or hand assembly; incompatible with automated SMT lines | Select only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with 1.5SMC82CAH, SMBJ85CA offers smaller size but reduced surge capacity, while 1.5KE82CA matches power rating but sacrifices SMT manufacturability - the 1.5SMC82CAH uniquely balances AEC-Q101 qualification, SMC package automation readiness, and full ISO 7637-2 compliance.

FAQ
What does the "CAH" suffix indicate in 1.5SMC82CAH?
The "CAH" suffix in 1.5SMC82CAH denotes a bidirectional configuration with AEC-Q101 qualification and halogen-free construction. Unlike unidirectional "H" variants, the CAH version provides symmetrical clamping in both polarities and meets automotive reliability standards per JESD22 and AEC-Q101 test suites. This makes 1.5SMC82CAH suitable for AC-coupled or polarity-agnostic surge protection paths where reverse voltage stress is possible.
Does 1.5SMC82CAH meet ISO 7637-2 Pulse 1 requirements?
Yes, 1.5SMC82CAH is explicitly validated to meet ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) per manufacturer documentation. Its 1500 W peak power rating, 113 V clamping voltage at 13.9 A, and fast <1.0 ps response enable reliable suppression of these standardized automotive transients without degradation or failure.
What is the maximum clamping voltage of 1.5SMC82CAH and under what test condition?
The maximum clamping voltage of 1.5SMC82CAH is 113 V, measured at a peak pulse current (IPPM) of 13.9 A using the 10/1000 µs double-exponential waveform defined in Fig.5 of the datasheet. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events and is guaranteed across the full operating temperature range of -55 °C to +150 °C.
Is 1.5SMC82CAH compatible with lead-free reflow soldering processes?
Yes, 1.5SMC82CAH is fully compatible with lead-free reflow soldering. Its matte tin-plated leads comply with J-STD-002 for solderability, and its DO-214AB (SMC) package is rated for moisture sensitivity level 1 per J-STD-020 - meaning it can be stored indefinitely at ambient conditions and placed directly into reflow without baking. The device withstands peak temperatures up to 260 °C per JEDEC J-STD-020.
How does the breakdown voltage tolerance of 1.5SMC82CAH compare to similar TVS diodes?
1.5SMC82CAH has a specified breakdown voltage range of 77.9 V to 86.1 V at 10 mA test current, representing a ±5% tolerance around the nominal 82 V rating. This tighter tolerance than many general-purpose TVS diodes (which often specify ±10%) ensures more predictable turn-on behavior in precision protection circuits - especially critical in automotive applications where margin between VWM (70.1 V) and VBR must be maintained across temperature and aging.
