Product details
Overview
1.5SMC160CAHE3_A/I 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 with 10/1000 μs waveform, 136 V standoff voltage (VWM), and 219 V clamping voltage (VC) at 6.8 A peak pulse current - deployed for lightning and inductive-switching surge protection on automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the 1.5SMC160CAHE3_A/I datasheet, 1.5SMC160CAHE3_A/I pinout, 1.5SMC160CAHE3_A/I application, or 1.5SMC160CAHE3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), junction temperature range (–65 to +150 °C), and bidirectional clamping behavior critical for ESD/surge co-design in safety-critical embedded systems.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) of 152–168 V at 1 mA test current and maximum reverse leakage (ID) ≤1.0 μA at 136 V standoff. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, supporting repetitive surge duty cycles up to 0.01 %.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C), JESD 201 Class 2 whisker resistance, and UL 94 V-0 flammability - confirming suitability for automated high-reliability production in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 136 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown) | 152–168 V at 1 mA - Confirmed symmetrical breakdown in both directions; ensures predictable turn-on during bidirectional transients. |
| VC (Clamping) | 219 V at IPPM = 6.8 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress level. |
| PPPM | 1500 W - Peak transient power handling capability under standardized 10/1000 μs waveform; validates robustness against lightning surges. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and high-ambient industrial settings. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Same VWM (136 V) and VC (219 V), but lower PPPM (600 W); SMB package (smaller footprint, higher RθJA = 110 °C/W). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4; preferred where board space is constrained and surge severity is moderate. | Select when PCB area is critical and surge threat level is ≤1 kV line-to-ground; verify thermal margin due to higher junction temperature rise. |
| 1.5KE160CA | Same electrical ratings (VWM, VBR, VC), but axial-leaded DO-201 package; not surface-mountable; higher mechanical stress sensitivity. | Requires through-hole assembly; incompatible with automated SMT lines; used only in legacy or low-volume prototyping. | Choose only for hand-soldered repairs or non-SMT designs; avoid in new automotive or industrial production due to mounting and reliability limitations. |

FAQ
What does the "CA" suffix indicate in 1.5SMC160CAHE3_A/I?
The "CA" suffix in 1.5SMC160CAHE3_A/I denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both forward and reverse polarities, with identical breakdown and clamping characteristics across its two terminals. This eliminates polarity-dependent placement during PCB layout and supports differential or common-mode surge protection schemes without requiring separate unidirectional devices.
Is 1.5SMC160CAHE3_A/I qualified for automotive use?
Yes, 1.5SMC160CAHE3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3", which designates RoHS-compliant and AEC-Q101 qualified variants. It has passed stress tests including high-temperature operating life (HTOL), temperature cycling, and unbiased highly accelerated stress testing (UHAST), making it suitable for under-hood and cabin-mounted automotive electronics.
What is the clamping voltage of 1.5SMC160CAHE3_A/I at its rated peak pulse current?
The clamping voltage (VC) of 1.5SMC160CAHE3_A/I is 219 V at its specified peak pulse current (IPPM) of 6.8 A, measured under the standardized 10/1000 μs double-exponential surge waveform. This value represents the maximum voltage imposed on the protected circuit during worst-case transient events and is critical for ensuring downstream ICs remain within their absolute maximum voltage ratings.
How does the SMC (DO-214AB) package of 1.5SMC160CAHE3_A/I compare thermally to smaller packages like SMB?
The SMC (DO-214AB) package of 1.5SMC160CAHE3_A/I offers significantly better thermal performance than SMB: its typical junction-to-ambient thermal resistance (RθJA) is 75 °C/W versus ~110 °C/W for SMBJ devices. This allows sustained power dissipation and higher surge repetition tolerance - especially important when mounted on recommended 8.0 mm × 8.0 mm copper pads per terminal.
Can 1.5SMC160CAHE3_A/I be used in place of a unidirectional TVS like 1.5SMC160AHE3_A/I?
No - 1.5SMC160CAHE3_A/I is strictly bidirectional and cannot replace a unidirectional part like 1.5SMC160AHE3_A/I in circuits requiring DC bias or polarity-sensitive clamping (e.g., power rail protection with defined anode/cathode orientation). The "CA" variant lacks cathode band marking and conducts equally in both directions, so substitution would compromise circuit functionality unless the design explicitly requires symmetrical suppression.
