Product details
Overview
1.5KE10CAHE3_B/C from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage (VC) at 103 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the 1.5KE10CAHE3_B/C datasheet, 1.5KE10CAHE3_B/C pinout, 1.5KE10CAHE3_B/C application, or 1.5KE10CAHE3_B/C equivalent, this device delivers verified bidirectional surge suppression with AEC-Q101 qualification, low clamping ratio, and RoHS-compliant HE3 packaging for high-reliability embedded designs.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), critical for suppressing ESD and lightning-induced surges before sensitive circuitry sustains damage.
The device uses a DO-201AD package with axial leads and is rated for -55 °C to +175 °C operating junction temperature. Thermal resistance from junction to lead is 15.4 °C/W, supporting robust surge handling under transient conditions when mounted with adequate lead length (0.375″/9.5 mm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VWM) | 10 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| Breakdown Voltage (VBR) | 9.5–10.5 V at 1 mA - precise voltage threshold where avalanche conduction initiates reliably across production lot. |
| Clamping Voltage (VC) | 14.5 V at 103 A (10/1000 µs) - limits transient voltage seen by protected circuitry; clamping ratio = 1.45. |
| Peak Pulse Power (PPPM) | 1500 W - energy-handling capacity for standardized 10/1000 µs surge; enables protection against IEC 61000-4-5 Level 4 events. |
| Operating Temperature | -55 °C to +175 °C - supports under-hood automotive and industrial environments without derating loss. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per JEDEC standard. |
| Package | DO-201AD (Case Style 1.5KE) - axial-leaded, epoxy-molded package with UL 94 V-0 flammability rating and matte tin plating. |
Pinout & Package
1.5KE10CAHE3_B/C is housed in a DO-201AD (Case Style 1.5KE) axial-leaded package with no polarity marking - consistent with bidirectional operation. Leads are matte tin-plated and solderable per J-STD-002/JESD 22-B102; meets JESD 201 Class 2 whisker test (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No functional distinction between terminals; either lead may connect to line or ground - simplifies PCB layout for AC or differential lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | DO-214AA package; lower 600 W PPPM; 17 V VC at 35.3 A; higher clamping ratio (1.7). | Preferred for space-constrained PCBs where 1500 W rating is not required; less effective for high-energy load dump. | Select SMBJ10CA only if board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3. |
| 1.5KE10CAHE3_A | Same electrical specs and DO-201AD package; differs only in revision code (A vs. B/C); identical AEC-Q101 qualification status. | No functional difference; B/C denotes updated manufacturing lot traceability and whisker test compliance (JESD 201 Class 2). | 1.5KE10CAHE3_A remains viable, but 1.5KE10CAHE3_B/C offers enhanced process control documentation for automotive OEM audits. |
Compared with SMBJ10CA, 1.5KE10CAHE3_B/C delivers 2.5× higher surge power handling and tighter clamping - essential for automotive and industrial mains-connected systems; versus 1.5KE10CAHE3_A, it provides updated reliability validation without design change.

FAQ
What is the clamping voltage of the 1.5KE10CAHE3_B/C at its rated peak pulse current?
The 1.5KE10CAHE3_B/C has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated 103 A peak pulse current with a 10/1000 µs waveform. This value is measured per JEDEC standard test conditions and reflects worst-case voltage seen by downstream circuitry during surge events. The 1.5KE10CAHE3_B/C maintains this clamping performance across its full operating temperature range (-55 °C to +175 °C), making it suitable for under-hood automotive use.
Is the 1.5KE10CAHE3_B/C suitable for bidirectional signal line protection?
Yes - the "CA" suffix explicitly denotes bidirectional configuration, meaning the 1.5KE10CAHE3_B/C functions identically in both polarities and requires no orientation during placement. It is commonly deployed across differential pairs (e.g., RS-485, CAN FD), AC-coupled audio paths, and ungrounded sensor bridges where polarity reversal or common-mode transients occur. Its symmetrical VBR (9.5–10.5 V) and matched clamping ensure balanced protection without introducing DC bias.
Does the 1.5KE10CAHE3_B/C meet automotive qualification standards?
Yes - the "HE3_B/C" suffix confirms AEC-Q101 qualification per Vishay's documentation (Document Number 88301, Note 2). This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and surge endurance. The 1.5KE10CAHE3_B/C is approved for use in automotive powertrain, chassis, and body electronics where sustained reliability under thermal and electrical stress is mandatory.
How does the 1.5KE10CAHE3_B/C compare to unidirectional variants like 1.5KE10AHE3_B/C?
The 1.5KE10CAHE3_B/C differs from unidirectional 1.5KE10AHE3_B/C solely in polarity configuration: the "CA" version provides symmetrical breakdown and clamping in both directions, while the "A" version has a defined cathode band and conducts only in reverse. Electrically, their VWM, VBR, and VC values are identical, but the 1.5KE10CAHE3_B/C eliminates polarity-dependent layout constraints - critical for AC signal paths and floating grounds where directionality cannot be assumed.
What is the thermal resistance and maximum power dissipation of the 1.5KE10CAHE3_B/C?
The 1.5KE10CAHE3_B/C has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W and a steady-state power dissipation (PD) of 6.5 W at TL = 75 °C (lead temperature). Its junction-to-ambient resistance is 75 °C/W, but this value is highly dependent on PCB copper area and airflow. For reliable long-term operation, the 1.5KE10CAHE3_B/C should be mounted with ≥0.375″ (9.5 mm) lead length to maintain thermal performance during repetitive surge events.
