Product details
Overview
1.5SMC180CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 154 V standoff voltage (VWM), and clamping to 246 V at 6.1 A peak pulse current. It protects automotive-grade sensor signal lines and power rails against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5SMC180CAHM3_A/H datasheet, 1.5SMC180CAHM3_A/H pinout, 1.5SMC180CAHM3_A/H application, or 1.5SMC180CAHM3_A/H equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS offers verified bidirectional clamping, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive and industrial PCB designs.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both directions due to its bidirectional construction. Its glass-passivated junction enables fast response time (<1 ns) and stable clamping under repetitive 10/1000 μs surges at 0.01% duty cycle.
Thermal performance is defined by RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.), with maximum junction temperature of +150 °C. It requires no polarity marking on the case and mounts on 8.0 mm × 8.0 mm copper pads per terminal for rated power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 154 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown, min/max) | 171 V / 189 V at 1 mA - Confirmed symmetric breakdown threshold in both directions; ensures predictable turn-on. |
| VC (Clamping, at IPPM) | 246 V at 6.1 A - Measured peak voltage during 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM | 1500 W - Peak pulse power handling capability under standard waveform; supports robust surge immunity per IEC 61000-4-5. |
| IPPM | 6.1 A - Peak pulse current corresponding to VC; used to size upstream fusing and trace routing. |
| TJ max. | +150 °C - Maximum junction temperature; sets thermal derating limits for sustained operation in enclosed environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180CA | Lower peak power (600 W), same VWM/VC, SMB package (smaller footprint, higher RθJA = 110 °C/W). | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy transients in space-constrained consumer ports. | Select when board area is critical and surge threat level is ≤Level 3; verify thermal margin at 600 W. |
| 1.5KE180CA | Through-hole DO-201 package, same electrical specs, but not AEC-Q101 qualified or MSL Level 1 rated. | Excludes automotive and high-volume SMT production; requires wave soldering and manual inspection. | Choose only for legacy through-hole designs or prototyping where reflow compatibility and automotive qualification are not required. |
Compared with SMBJ180CA and 1.5KE180CA, the 1.5SMC180CAHM3_A/H delivers higher surge robustness in an automotive-qualified SMT package - enabling single-source compliance for Tier 1 suppliers needing AEC-Q101, MSL-1, and halogen-free requirements without layout or process changes.

FAQ
What is the clamping voltage of the 1.5SMC180CAHM3_A/H at its rated peak pulse current?
The 1.5SMC180CAHM3_A/H clamps to a maximum of 246 V when subjected to its specified peak pulse current of 6.1 A under the 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC180CAHM3_A/H maintains this clamping performance across its full operating temperature range of -65 °C to +150 °C.
Is the 1.5SMC180CAHM3_A/H suitable for automotive applications?
Yes, the 1.5SMC180CAHM3_A/H is AEC-Q101 qualified and explicitly designated for automotive use via the "HM3" suffix, indicating halogen-free, RoHS-compliant construction and qualification to automotive reliability stress tests. It is deployed in engine control units, body electronics, and ADAS sensor interfaces where compliance with ISO 7637-2 and ISO 16750-2 is required. The 1.5SMC180CAHM3_A/H meets these standards when mounted per the recommended 8.0 mm × 8.0 mm copper pad layout.
What does the "CA" suffix indicate in 1.5SMC180CAHM3_A/H?
The "CA" suffix in 1.5SMC180CAHM3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities without polarity dependence. Unlike unidirectional variants (e.g., "A" suffix), the 1.5SMC180CAHM3_A/H has no cathode band marking and functions identically whether installed in either orientation across a protected line pair. This makes it ideal for differential signal protection such as CAN, RS-485, or USB data lines.
What is the maximum operating temperature for the 1.5SMC180CAHM3_A/H?
The 1.5SMC180CAHM3_A/H has a maximum junction temperature (TJ) rating of +150 °C, with storage temperature extending from -65 °C to +150 °C. Its thermal resistance from junction to ambient (RθJA) is 75 °C/W under standard mounting conditions (0.31″ × 0.31″ copper pads). Derating curves in Figure 2 of datasheet 88303 show that at 100 °C ambient, the device retains >60% of its 1500 W peak pulse capability - confirming suitability for under-hood automotive environments.
How does the 1.5SMC180CAHM3_A/H differ from the non-HM3 version?
The 1.5SMC180CAHM3_A/H differs from non-HM3 versions (e.g., 1.5SMC180CA-E3) by being halogen-free, RoHS-compliant, and AEC-Q101 qualified - confirmed by the "HM3" suffix. It also meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability. Electrically and thermally, the 1.5SMC180CAHM3_A/H matches the base series, but its material composition and qualification scope make it mandatory for automotive Tier 1 supply chains and green manufacturing programs.
