Product details
Overview
SA10CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 500 W peak pulse power (10/1000 μs), 10 V stand-off voltage (VWM), 12.9 V maximum clamping voltage at 20.5 A (VC), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA10CAHE3/54 datasheet, SA10CAHE3/54 pinout, SA10CAHE3/54 application, or SA10CAHE3/54 equivalent, this device is selected for robust ESD and surge protection in sensor interfaces, automotive control modules, and industrial I/O circuits where bidirectional clamping and high surge current tolerance are required.
Technical Context
The SA10CAHE3/54 operates as a bidirectional avalanche diode with symmetrical breakdown characteristics in both polarities. Its 6.4–7.25 V breakdown voltage range (VBR at 10 mA) ensures precise clamping onset, while low incremental surge resistance enables effective energy diversion during fast transients like ISO 7637-2 pulses or EFT bursts.
Designed for surface-mount-compatible through-hole assembly, it leverages glass-passivated junction technology and matte tin-plated leads compliant with J-STD-002. The device sustains 175 °C maximum junction temperature and meets UL 94 V-0 flammability requirements in its molded epoxy DO-15 housing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 12 V nominal systems. |
| VBR (min/max) | 6.4 V / 7.25 V at 10 mA - Confirmed bidirectional breakdown threshold; ensures consistent clamping symmetry across polarity. |
| VC @ IPPM | 12.9 V at 20.5 A - Clamped voltage under 10/1000 μs surge; limits downstream IC stress to safe levels in automotive load-dump scenarios. |
| PPPM | 500 W - Peak pulse power handling per single transient; supports repetitive surges up to 0.01% duty cycle without degradation. |
| IPPM | 20.5 A - Maximum non-repetitive peak pulse current; validates capability against IEC 61000-4-5 Level 3 (1 Ω/2 Ω coupling). |
| TJ max. | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| Package | DO-15 (DO-204AC) - Standard axial-leaded outline with 0.242–0.258 inch body length; compatible with legacy wave-solder and hand-solder processes. |
Pinout & Package
DO-15 (DO-204AC) package: axial-leaded, molded epoxy case with no polarity marking (bidirectional configuration). Leads are matte tin-plated, solderable per J-STD-002, rated for 275 °C dip soldering (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bidirectional avalanche junction | No cathode band; terminals are electrically symmetric - either lead may connect to line or ground in AC-coupled or floating applications. |
| Lead 1 | Current path input | Accepts transient current from protected line; forms one side of the clamping loop with Lead 2. |
| Lead 2 | Current path return | Completes clamping path to reference plane (e.g., chassis ground or common rail); no directional dependency. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Enables stable, low-leakage (<1.0 μA at VWM) performance over temperature and lifetime, critical for low-power sensor bias networks. |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD-HBM/MM, supporting ASIL-B system integration. |
| 500 W peak pulse power (10/1000 μs) | Handles high-energy transients such as ISO 16750-2 load dump spikes without failure, reducing need for cascaded protection stages. |
| Low clamping ratio (VC/VBR ≈ 1.8) | Minimizes overvoltage exposure to downstream components - e.g., 12.9 V clamp protects 12 V-rated CAN transceivers during 100 V surges. |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed industrial or automotive housings, satisfying safety compliance for end-equipment certification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V) and PPPM (400 W), but SMA package (surface-mount); lower IPPM (17.4 A) and higher VC (17.0 V). | Requires PCB rework for SMT layout; less suitable for through-hole legacy designs or high-vibration mechanical mounting. | Select when board space is constrained and automated assembly is prioritized over serviceability. |
| P6KE10CA | Same DO-15 package and bidirectional function, but lower PPPM (600 W), higher VC (16.7 V), and no AEC-Q101 qualification. | Lacks automotive qualification; clamps at higher voltage, increasing risk to 12 V logic interfaces during severe transients. | Select for cost-sensitive industrial applications where AEC-Q101 is not mandated and 16.7 V clamp is acceptable. |
Compared with SMAJ10CA and P6KE10CA, SA10CAHE3/54 delivers tighter clamping (12.9 V vs. ≥16.7 V), guaranteed automotive qualification, and optimal fit for existing DO-15 through-hole production lines - making it the preferred choice for mission-critical 12 V system protection where reliability and mechanical robustness are paramount.

FAQ
What is the clamping voltage of SA10CAHE3/54 under a 10/1000 μs surge?
The SA10CAHE3/54 exhibits a maximum clamping voltage (VC) of 12.9 V at its rated peak pulse current of 20.5 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and reflects the upper limit of voltage seen by protected circuitry during worst-case transient events - a key parameter for ensuring compatibility with 12 V logic and interface ICs downstream of the SA10CAHE3/54.
Is SA10CAHE3/54 suitable for automotive applications?
Yes, SA10CAHE3/54 is AEC-Q101 qualified (denoted by the HE3 suffix), having passed rigorous stress tests including high-temperature operating life, temperature cycling, and ESD robustness. Its 175 °C maximum junction temperature, glass-passivated junction, and UL 94 V-0 package make it appropriate for under-hood and body-control module deployments where SA10CAHE3/54 serves as primary transient suppression on LIN, CAN, or sensor supply lines.
How does the bidirectional nature of SA10CAHE3/54 affect its placement in a circuit?
The SA10CAHE3/54 has no polarity marking and functions identically in both directions, allowing flexible placement across any two points needing transient suppression - such as between differential signal pairs, AC-coupled lines, or floating power domains. Unlike unidirectional TVS diodes, SA10CAHE3/54 eliminates orientation errors during assembly and supports symmetrical clamping in systems subject to bipolar voltage excursions, like automotive battery reverse-connection transients.
What is the maximum steady-state power dissipation of SA10CAHE3/54?
The SA10CAHE3/54 has a maximum steady-state power dissipation (PD) of 3.0 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C. This rating governs continuous leakage-related heating under sustained overvoltage conditions - though in normal operation, SA10CAHE3/54 remains inactive below 10 V and only dissipates significant power during transient events, where its 500 W peak rating dominates design considerations.
Does SA10CAHE3/54 require additional series impedance for optimal performance?
Yes, SA10CAHE3/54 performs best when paired with series impedance - typically a ferrite bead or small resistor (e.g., 1–10 Ω) - placed between the protected node and the SA10CAHE3/54 anode/cathode terminals. This impedance slows the transient rise time, reduces peak current demand on SA10CAHE3/54, and improves overall clamping effectiveness; data sheet Fig. 7–10 confirm lower incremental VC with added source impedance, especially for fast 8/20 μs waveforms.
