Product details
Overview
1.5SMC160CAHE3_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 with 10/1000 μs waveform, 160 V standoff voltage (VWM), and clamping voltage of 219 V at 6.8 A peak pulse current - used to protect automotive sensor signal lines, industrial I/O ports, and telecom interface circuits against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5SMC160CAHE3_A/H datasheet, 1.5SMC160CAHE3_A/H pinout, 1.5SMC160CAHE3_A/H application, or 1.5SMC160CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C maximum junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This device operates as a voltage-clamped transient protector: under normal conditions it presents high impedance (>1 MΩ at 136 V), but switches to low-impedance conduction within <1 ns when reverse voltage exceeds its breakdown threshold (152–168 V). Its bidirectional symmetry enables protection of AC-coupled or differential signal paths without polarity constraints.
Thermal performance is defined by RθJA = 75 °C/W (on 8 mm × 8 mm copper pads) and RθJL = 15 °C/W, supporting sustained 6.5 W power dissipation at 50 °C ambient. It meets J-STD-020 MSL Level 1 and passes JESD201 Class 2 whisker testing with matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 136 V - maximum continuous reverse operating voltage before significant leakage; defines safe operating margin below clamping onset |
| VBR (Breakdown) | 152–168 V at 1 mA - guaranteed voltage range where device transitions from high- to low-impedance state |
| VC (Clamping) | 219 V at IPPM = 6.8 A - peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress |
| PPPM | 1500 W - peak transient energy absorption capacity per single 10/1000 μs pulse; supports robust lightning surge immunity |
| ID (Leakage) | 1.0 μA max at VWM - ensures minimal standby power loss and signal integrity in high-impedance interfaces |
| TJ max | +150 °C - enables operation in under-hood automotive and industrial environments without thermal derating penalties |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC specification |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile plastic case with matte tin-plated leads; dimensions 7.75 mm × 6.22 mm × 2.62 mm (L × W × H); UL 94 V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Terminal 1 | One side of bidirectional junction; no polarity marking required - interchangeable with cathode in AC protection |
| Cathode | Terminal 2 | Other side of bidirectional junction; symmetric conduction eliminates orientation dependency during PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC, differential, or floating signal lines without external polarity management |
| 1500 W peak pulse rating | Meets IEC 61000-4-5 Level 4 (4 kV line-to-line) surge immunity requirements with margin |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, ADAS sensors, and infotainment interfaces |
| MSL Level 1 handling | Allows unlimited floor life and reflow at 260 °C peak without baking - simplifies SMT manufacturing flow |
| Glass-passivated junction | Ensures stable VBR over time and temperature; reduces parameter drift vs. epoxy-passivated alternatives |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN FD and LIN bus transceivers in vehicle body control modules from load-dump and ISO 7637-2 pulses.

IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp limiting output voltage overshoot during hot-plug events. Use Value: Maintains <0.5 pF junction capacitance at 0 V bias - avoids signal distortion in 3 A/20 V output regulation loop. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient 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) | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive load-dump scenarios | Select when board space is constrained and surge threat level is ≤2 kV. |
| 1.5KE160CA | Through-hole DO-201 package; identical electrical specs but incompatible with SMT assembly and higher thermal resistance | Requires manual or wave-solder process; not viable for high-volume automated production | Choose only for legacy repair or prototyping where rework flexibility outweighs production efficiency. |
Compared with SMBJ160CA and 1.5KE160CA, the 1.5SMC160CAHE3_A/H delivers full 1500 W surge handling in an AEC-Q101-qualified SMT package - enabling automotive-grade reliability, automated placement, and thermal performance unattainable with smaller or through-hole alternatives.

FAQ
What is the clamping voltage of the 1.5SMC160CAHE3_A/H under a 10/1000 μs surge?
The 1.5SMC160CAHE3_A/H clamps to a maximum of 219 V when subjected to its rated peak pulse current of 6.8 A using the standardized 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 transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC160CAHE3_A/H suitable for automotive applications?
Yes, the 1.5SMC160CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" suffix and "_A/H" revision code. It has passed stress tests including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D, making it appropriate for engine control units, ADAS camera modules, and body electronics where reliability under thermal and electrical stress is mandatory.
What does the "CA" suffix indicate in 1.5SMC160CAHE3_A/H?
The "CA" suffix in 1.5SMC160CAHE3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities. Unlike unidirectional variants (e.g., "A" suffix), it has no cathode marking and functions identically regardless of voltage polarity, enabling simplified design for AC-coupled, differential, or floating signal lines.
What is the maximum operating temperature for the 1.5SMC160CAHE3_A/H?
The 1.5SMC160CAHE3_A/H has a maximum junction temperature (TJ) of +150 °C, verified per Vishay's thermal characterization in document 88303. This allows continuous operation in under-hood automotive environments and industrial enclosures without forced cooling, provided PCB copper pad layout follows the recommended 8.0 mm × 8.0 mm minimum per terminal.
How does the 1.5SMC160CAHE3_A/H differ from the 1.5SMC160AHE3_A/H?
The 1.5SMC160CAHE3_A/H is bidirectional (CA), while the 1.5SMC160AHE3_A/H is unidirectional (A). Their VWM (136 V), VBR (152–168 V), and VC (219 V) match, but the unidirectional version requires correct polarity orientation during placement and conducts forward current only in one direction - making the CA variant preferable for differential buses like CAN or RS-485 where polarity reversal may occur.
