Product details
Overview
P6SMB13CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 13 V breakdown voltage (VBR min/max = 12.4–13.7 V at 1.0 mA), 11.1 V stand-off voltage (VWM), and clamps to ≤18.2 V at 33.0 A peak pulse current (10/1000 μs), delivering 600 W peak pulse power for automotive-grade ESD and surge protection.
For engineers reviewing the P6SMB13CAHM3/H datasheet, P6SMB13CAHM3/H pinout, P6SMB13CAHM3/H application, or P6SMB13CAHM3/H equivalent, this AEC-Q101-qualified, halogen-free, RoHS-compliant TVS diode supports robust transient suppression in sensor interfaces, power supply rails, and communication lines where bidirectional clamping and MSL Level 1 reflow compatibility are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions-enabling simplified layout for AC-coupled or floating signal paths. Its glass-passivated junction ensures stable leakage (<5.0 μA at VWM) and fast response time (<1.0 ns), critical for protecting sensitive analog inputs and high-speed digital receivers.
The device uses a low-inductance SMB (DO-214AA) package with matte tin-plated leads solderable per J-STD-002, and its thermal resistance (RθJA = 100 °C/W) supports operation up to +150 °C junction temperature under defined PCB pad conditions (0.2" × 0.2" copper per terminal).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 12.4–13.7 V at 1.0 mA - defines minimum clamping threshold under transient stress |
| Stand-off Voltage VWM | 11.1 V - maximum continuous reverse voltage before significant leakage begins |
| Clamping Voltage VC | ≤18.2 V at 33.0 A (10/1000 μs) - limits downstream IC voltage during surge events |
| Peak Pulse Power PPPM | 600 W - sustains short-duration surges without failure (0.01% duty cycle) |
| Maximum Leakage ID | ≤5.0 μA at VWM - negligible loading on low-power sensor or reference circuits |
| Operating Temperature | −65 °C to +150 °C - suitable for under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including temperature cycling, HTRB, and ESD |

Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting analog output pins of pressure, temperature, or position sensors exposed to load-dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed directly at connector or sensor IC input. Use Value: Limits voltage excursion to ≤18.2 V during 33 A transients, preserving sensor accuracy and preventing latch-up in 3.3 V or 5 V signal chains. |
Use Scenario: Guarding CAN_H and CAN_L lines against ESD (IEC 61000-4-2 ±8 kV contact) and burst noise in factory automation controllers. IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF), fast-response shunt protector on differential bus lines. Use Value: Maintains signal integrity with sub-ns response and <5 μA leakage, avoiding CAN bit timing distortion or false dominant detection. |
| Power Supply Rail Clamp | USB Port ESD Protection |
Use Scenario: Secondary overvoltage clamp on 12 V auxiliary rails feeding infotainment or telematics modules after primary DC/DC regulation. IC Role / Device Role / Timing Role: Standby-mode surge limiter parallel to bulk capacitance, activated only during transients >11.1 V. Use Value: Absorbs 600 W pulses without derating at +85 °C ambient, enabling compact layout with minimal thermal margin overhead. |
Use Scenario: Board-level ESD protection for USB 2.0 D+ and D− lines in portable diagnostic tools or vehicle data loggers. IC Role / Device Role / Timing Role: Symmetric bidirectional suppressor placed before USB transceiver IC, compliant with USB 2.0 eye diagram requirements. Use Value: Clamps ±15 kV ESD strikes to <18.2 V while adding <0.5 pF parasitic capacitance per line-no USB signal degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM/VBR/VC specs but lower PPPM (400 W), SMA package (larger footprint, higher RθJA) | Limited to lower-energy surges; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 600 W headroom |
| 1.5KE13CA | Through-hole TO-204AA (DO-41), 600 W rating, but slower response (>5 ns) and no MSL Level 1 support | Requires wave solder or hand-solder; unsuitable for automated SMT lines or high-reliability reflow | Choose only for legacy through-hole designs where board space and assembly process permit |
Compared with SMAJ13CA and 1.5KE13CA, P6SMB13CAHM3/H delivers AEC-Q101 validation, MSL Level 1 reflow readiness, and identical 600 W surge capability in a compact SMB footprint-making it the preferred choice for new automotive and industrial SMT designs requiring production scalability and long-term reliability assurance.

FAQ
What does the "CA" suffix indicate in P6SMB13CAHM3/H?
The "CA" suffix denotes a bidirectional configuration: P6SMB13CAHM3/H provides symmetrical clamping in both polarities, unlike unidirectional variants (e.g., P6SMB13AHM3/H). This enables use on AC-coupled lines, differential buses, or floating nodes without polarity constraints-critical for CAN, RS-485, or sensor bridge outputs where voltage polarity reverses dynamically. The CA version maintains identical VBR, VC, and PPPM ratings in either direction.
Is P6SMB13CAHM3/H suitable for IEC 61000-4-5 surge testing?
Yes, P6SMB13CAHM3/H is rated for 600 W peak pulse power with a 10/1000 μs waveform, which covers IEC 61000-4-5 Level 4 (4 kV line-to-earth, 2 kV line-to-line) when implemented with recommended PCB layout-specifically 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Its low clamping voltage (≤18.2 V) ensures protected circuitry remains within safe operating limits during standardized surge events.
How does the HM3 suffix differ from M3 or E3 in P6SMB13CAHM3/H?
The HM3 suffix indicates halogen-free, RoHS-compliant construction *and* AEC-Q101 qualification-distinguishing it from M3 (halogen-free/RoHS only) and E3 (RoHS only). P6SMB13CAHM3/H undergoes extended automotive reliability testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD qualification per AEC-Q101 Rev G, making it suitable for under-hood and safety-critical automotive applications where M3/E3 variants are not approved.
What is the maximum steady-state power dissipation for P6SMB13CAHM3/H?
P6SMB13CAHM3/H has a maximum steady-state power dissipation (PD) of 5.0 W at TA = 50 °C on an infinite heatsink. In typical SMB surface-mount layouts, derating applies above 25 °C ambient; for example, at 85 °C ambient, usable PD drops to ~3.0 W. This rating governs continuous leakage power-not transient surge energy-and must be verified against actual board thermal design using the specified 100 °C/W junction-to-ambient thermal resistance.
Does P6SMB13CAHM3/H require orientation during PCB placement?
No-P6SMB13CAHM3/H is a bidirectional device with no polarity marking or functional anode/cathode distinction. Both terminals are electrically identical, allowing unrestricted placement on PCBs. This eliminates orientation errors during automated assembly and simplifies layout for differential or AC-coupled signal paths, unlike unidirectional TVS diodes (e.g., P6SMB13AHM3/H) that require band-aligned cathode placement.
